Introduction =============== miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file: ```c #define MINIAUDIO_IMPLEMENTATION #include "miniaudio.h" ``` You can do `#include "miniaudio.h"` in other parts of the program just like any other header. miniaudio includes both low level and high level APIs. The low level API is good for those who want to do all of their mixing themselves and only require a light weight interface to the underlying audio device. The high level API is good for those who have complex mixing and effect requirements. In miniaudio, objects are transparent structures. Unlike many other libraries, there are no handles to opaque objects which means you need to allocate memory for objects yourself. In the examples presented in this documentation you will often see objects declared on the stack. You need to be careful when translating these examples to your own code so that you don't accidentally declare your objects on the stack and then cause them to become invalid once the function returns. In addition, you must ensure the memory address of your objects remain the same throughout their lifetime. You therefore cannot be making copies of your objects. A config/init pattern is used throughout the entire library. The idea is that you set up a config object and pass that into the initialization routine. The advantage to this system is that the config object can be initialized with logical defaults and new properties added to it without breaking the API. The config object can be allocated on the stack and does not need to be maintained after initialization of the corresponding object. 1.1. Low Level API ------------------ The low level API gives you access to the raw audio data of an audio device. It supports playback, capture, full-duplex and loopback (WASAPI only). You can enumerate over devices to determine which physical device(s) you want to connect to. The low level API uses the concept of a "device" as the abstraction for physical devices. The idea is that you choose a physical device to emit or capture audio from, and then move data to/from the device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a callback which you specify when initializing the device. When initializing the device you first need to configure it. The device configuration allows you to specify things like the format of the data delivered via the callback, the size of the internal buffer and the ID of the device you want to emit or capture audio from. Once you have the device configuration set up you can initialize the device. When initializing a device you need to allocate memory for the device object beforehand. This gives the application complete control over how the memory is allocated. In the example below we initialize a playback device on the stack, but you could allocate it on the heap if that suits your situation better. ```c void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) { // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than // frameCount frames. } int main() { ma_device_config config = ma_device_config_init(ma_device_type_playback); config.playback.format = ma_format_f32; // Set to ma_format_unknown to use the device's native format. config.playback.channels = 2; // Set to 0 to use the device's native channel count. config.sampleRate = 48000; // Set to 0 to use the device's native sample rate. config.dataCallback = data_callback; // This function will be called when miniaudio needs more data. config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData). ma_device device; if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) { return -1; // Failed to initialize the device. } ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually. // Do something here. Probably your program's main loop. ma_device_uninit(&device); // This will stop the device so no need to do that manually. return 0; } ``` In the example above, `data_callback()` is where audio data is written and read from the device. The idea is in playback mode you cause sound to be emitted from the speakers by writing audio data to the output buffer (`pOutput` in the example). In capture mode you read data from the input buffer (`pInput`) to extract sound captured by the microphone. The `frameCount` parameter tells you how many frames can be written to the output buffer and read from the input buffer. A "frame" is one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 samples: one for the left, one for the right. The channel count is defined by the device config. The size in bytes of an individual sample is defined by the sample format which is also specified in the device config. Multi-channel audio data is always interleaved, which means the samples for each frame are stored next to each other in memory. For example, in a stereo stream the first pair of samples will be the left and right samples for the first frame, the second pair of samples will be the left and right samples for the second frame, etc. The configuration of the device is defined by the `ma_device_config` structure. The config object is always initialized with `ma_device_config_init()`. It's important to always initialize the config with this function as it initializes it with logical defaults and ensures your program doesn't break when new members are added to the `ma_device_config` structure. The example above uses a fairly simple and standard device configuration. The call to `ma_device_config_init()` takes a single parameter, which is whether or not the device is a playback, capture, duplex or loopback device (loopback devices are not supported on all backends). The `config.playback.format` member sets the sample format which can be one of the following (all formats are native-endian): +---------------+----------------------------------------+---------------------------+ | Symbol | Description | Range | +---------------+----------------------------------------+---------------------------+ | ma_format_f32 | 32-bit floating point | [-1, 1] | | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | | ma_format_u8 | 8-bit unsigned integer | [0, 255] | +---------------+----------------------------------------+---------------------------+ The `config.playback.channels` member sets the number of channels to use with the device. The channel count cannot exceed MA_MAX_CHANNELS. The `config.sampleRate` member sets the sample rate (which must be the same for both playback and capture in full-duplex configurations). This is usually set to 44100 or 48000, but can be set to anything. It's recommended to keep this between 8000 and 384000, however. Note that leaving the format, channel count and/or sample rate at their default values will result in the internal device's native configuration being used which is useful if you want to avoid the overhead of miniaudio's automatic data conversion. In addition to the sample format, channel count and sample rate, the data callback and user data pointer are also set via the config. The user data pointer is not passed into the callback as a parameter, but is instead set to the `pUserData` member of `ma_device` which you can access directly since all miniaudio structures are transparent. Initializing the device is done with `ma_device_init()`. This will return a result code telling you what went wrong, if anything. On success it will return `MA_SUCCESS`. After initialization is complete the device will be in a stopped state. To start it, use `ma_device_start()`. Uninitializing the device will stop it, which is what the example above does, but you can also stop the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again. Note that it's important to never stop or start the device from inside the callback. This will result in a deadlock. Instead you set a variable or signal an event indicating that the device needs to stop and handle it in a different thread. The following APIs must never be called inside the callback: ```c ma_device_init() ma_device_init_ex() ma_device_uninit() ma_device_start() ma_device_stop() ``` You must never try uninitializing and reinitializing a device inside the callback. You must also never try to stop and start it from inside the callback. There are a few other things you shouldn't do in the callback depending on your requirements, however this isn't so much a thread-safety thing, but rather a real-time processing thing which is beyond the scope of this introduction. The example above demonstrates the initialization of a playback device, but it works exactly the same for capture. All you need to do is change the device type from `ma_device_type_playback` to `ma_device_type_capture` when setting up the config, like so: ```c ma_device_config config = ma_device_config_init(ma_device_type_capture); config.capture.format = MY_FORMAT; config.capture.channels = MY_CHANNEL_COUNT; ``` In the data callback you just read from the input buffer (`pInput` in the example above) and leave the output buffer alone (it will be set to NULL when the device type is set to `ma_device_type_capture`). These are the available device types and how you should handle the buffers in the callback: +-------------------------+--------------------------------------------------------+ | Device Type | Callback Behavior | +-------------------------+--------------------------------------------------------+ | ma_device_type_playback | Write to output buffer, leave input buffer untouched. | | ma_device_type_capture | Read from input buffer, leave output buffer untouched. | | ma_device_type_duplex | Read from input buffer, write to output buffer. | | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. | +-------------------------+--------------------------------------------------------+ You will notice in the example above that the sample format and channel count is specified separately for playback and capture. This is to support different data formats between the playback and capture devices in a full-duplex system. An example may be that you want to capture audio data as a monaural stream (one channel), but output sound to a stereo speaker system. Note that if you use different formats between playback and capture in a full-duplex configuration you will need to convert the data yourself. There are functions available to help you do this which will be explained later. The example above did not specify a physical device to connect to which means it will use the operating system's default device. If you have multiple physical devices connected and you want to use a specific one you will need to specify the device ID in the configuration, like so: ```c config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device. config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device. ``` To retrieve the device ID you will need to perform device enumeration, however this requires the use of a new concept called the "context". Conceptually speaking the context sits above the device. There is one context to many devices. The purpose of the context is to represent the backend at a more global level and to perform operations outside the scope of an individual device. Mainly it is used for performing run-time linking against backend libraries, initializing backends and enumerating devices. The example below shows how to enumerate devices. ```c ma_context context; if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) { // Error. } ma_device_info* pPlaybackInfos; ma_uint32 playbackCount; ma_device_info* pCaptureInfos; ma_uint32 captureCount; if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) { // Error. } // Loop over each device info and do something with it. Here we just print the name with their index. You may want // to give the user the opportunity to choose which device they'd prefer. for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) { printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name); } ma_device_config config = ma_device_config_init(ma_device_type_playback); config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id; config.playback.format = MY_FORMAT; config.playback.channels = MY_CHANNEL_COUNT; config.sampleRate = MY_SAMPLE_RATE; config.dataCallback = data_callback; config.pUserData = pMyCustomData; ma_device device; if (ma_device_init(&context, &config, &device) != MA_SUCCESS) { // Error } ... ma_device_uninit(&device); ma_context_uninit(&context); ``` The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. The first parameter is a pointer to a list of `ma_backend` values which are used to override the default backend priorities. When this is NULL, as in this example, miniaudio's default priorities are used. The second parameter is the number of backends listed in the array pointed to by the first parameter. The third parameter is a pointer to a `ma_context_config` object which can be NULL, in which case defaults are used. The context configuration is used for setting the logging callback, custom memory allocation callbacks, user-defined data and some backend-specific configurations. Once the context has been initialized you can enumerate devices. In the example above we use the simpler `ma_context_get_devices()`, however you can also use a callback for handling devices by using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer to a pointer that will, upon output, be set to a pointer to a buffer containing a list of `ma_device_info` structures. You also provide a pointer to an unsigned integer that will receive the number of items in the returned buffer. Do not free the returned buffers as their memory is managed internally by miniaudio. The `ma_device_info` structure contains an `id` member which is the ID you pass to the device config. It also contains the name of the device which is useful for presenting a list of devices to the user via the UI. When creating your own context you will want to pass it to `ma_device_init()` when initializing the device. Passing in NULL, like we do in the first example, will result in miniaudio creating the context for you, which you don't want to do since you've already created a context. Note that internally the context is only tracked by it's pointer which means you must not change the location of the `ma_context` object. If this is an issue, consider using `malloc()` to allocate memory for the context. 1.2. High Level API ------------------- The high level API consists of three main parts: * Resource management for loading and streaming sounds. * A node graph for advanced mixing and effect processing. * A high level "engine" that wraps around the resource manager and node graph. The resource manager (`ma_resource_manager`) is used for loading sounds. It supports loading sounds fully into memory and also streaming. It will also deal with reference counting for you which avoids the same sound being loaded multiple times. The node graph is used for mixing and effect processing. The idea is that you connect a number of nodes into the graph by connecting each node's outputs to another node's inputs. Each node can implement it's own effect. By chaining nodes together, advanced mixing and effect processing can be achieved. The engine encapsulates both the resource manager and the node graph to create a simple, easy to use high level API. The resource manager and node graph APIs are covered in more later sections of this manual. The code below shows how you can initialize an engine using it's default configuration. ```c ma_result result; ma_engine engine; result = ma_engine_init(NULL, &engine); if (result != MA_SUCCESS) { return result; // Failed to initialize the engine. } ``` This creates an engine instance which will initialize a device internally which you can access with `ma_engine_get_device()`. It will also initialize a resource manager for you which can be accessed with `ma_engine_get_resource_manager()`. The engine itself is a node graph (`ma_node_graph`) which means you can pass a pointer to the engine object into any of the `ma_node_graph` APIs (with a cast). Alternatively, you can use `ma_engine_get_node_graph()` instead of a cast. Note that all objects in miniaudio, including the `ma_engine` object in the example above, are transparent structures. There are no handles to opaque structures in miniaudio which means you need to be mindful of how you declare them. In the example above we are declaring it on the stack, but this will result in the struct being invalidated once the function encapsulating it returns. If allocating the engine on the heap is more appropriate, you can easily do so with a standard call to `malloc()` or whatever heap allocation routine you like: ```c ma_engine* pEngine = malloc(sizeof(*pEngine)); ``` The `ma_engine` API uses the same config/init pattern used all throughout miniaudio. To configure an engine, you can fill out a `ma_engine_config` object and pass it into the first parameter of `ma_engine_init()`: ```c ma_result result; ma_engine engine; ma_engine_config engineConfig; engineConfig = ma_engine_config_init(); engineConfig.pResourceManager = &myCustomResourceManager; // <-- Initialized as some earlier stage. result = ma_engine_init(&engineConfig, &engine); if (result != MA_SUCCESS) { return result; } ``` This creates an engine instance using a custom config. In this particular example it's showing how you can specify a custom resource manager rather than having the engine initialize one internally. This is particularly useful if you want to have multiple engine's share the same resource manager. The engine must be uninitialized with `ma_engine_uninit()` when it's no longer needed. By default the engine will be started, but nothing will be playing because no sounds have been initialized. The easiest but least flexible way of playing a sound is like so: ```c ma_engine_play_sound(&engine, "my_sound.wav", NULL); ``` This plays what miniaudio calls an "inline" sound. It plays the sound once, and then puts the internal sound up for recycling. The last parameter is used to specify which sound group the sound should be associated with which will be explained later. This particular way of playing a sound is simple, but lacks flexibility and features. A more flexible way of playing a sound is to first initialize a sound: ```c ma_result result; ma_sound sound; result = ma_sound_init_from_file(&engine, "my_sound.wav", 0, NULL, NULL, &sound); if (result != MA_SUCCESS) { return result; } ma_sound_start(&sound); ``` This returns a `ma_sound` object which represents a single instance of the specified sound file. If you want to play the same file multiple times simultaneously, you need to create one sound for each instance. Sounds should be uninitialized with `ma_sound_uninit()`. Sounds are not started by default. Start a sound with `ma_sound_start()` and stop it with `ma_sound_stop()`. When a sound is stopped, it is not rewound to the start. Use `ma_sound_seek_to_pcm_frame(&sound, 0)` to seek back to the start of a sound. By default, starting and stopping sounds happens immediately, but sometimes it might be convenient to schedule the sound the be started and/or stopped at a specific time. This can be done with the following functions: ```c ma_sound_set_start_time_in_pcm_frames() ma_sound_set_start_time_in_milliseconds() ma_sound_set_stop_time_in_pcm_frames() ma_sound_set_stop_time_in_milliseconds() ``` The start/stop time needs to be specified based on the absolute timer which is controlled by the engine. The current global time time in PCM frames can be retrieved with `ma_engine_get_time_in_pcm_frames()`. The engine's global time can be changed with `ma_engine_set_time_in_pcm_frames()` for synchronization purposes if required. Note that scheduling a start time still requires an explicit call to `ma_sound_start()` before anything will play: ```c ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2); ma_sound_start(&sound); ``` The third parameter of `ma_sound_init_from_file()` is a set of flags that control how the sound be loaded and a few options on which features should be enabled for that sound. By default, the sound is synchronously loaded fully into memory straight from the file system without any kind of decoding. If you want to decode the sound before storing it in memory, you need to specify the `MA_SOUND_FLAG_DECODE` flag. This is useful if you want to incur the cost of decoding at an earlier stage, such as a loading stage. Without this option, decoding will happen dynamically at mixing time which might be too expensive on the audio thread. If you want to load the sound asynchronously, you can specify the `MA_SOUND_FLAG_ASYNC` flag. This will result in `ma_sound_init_from_file()` returning quickly, but the sound will not start playing until the sound has had some audio decoded. The fourth parameter is a pointer to sound group. A sound group is used as a mechanism to organise sounds into groups which have their own effect processing and volume control. An example is a game which might have separate groups for sfx, voice and music. Each of these groups have their own independent volume control. Use `ma_sound_group_init()` or `ma_sound_group_init_ex()` to initialize a sound group. Sounds and sound groups are nodes in the engine's node graph and can be plugged into any `ma_node` API. This makes it possible to connect sounds and sound groups to effect nodes to produce complex effect chains. A sound can have it's volume changed with `ma_sound_set_volume()`. If you prefer decibel volume control you can use `ma_volume_db_to_linear()` to convert from decibel representation to linear. Panning and pitching is supported with `ma_sound_set_pan()` and `ma_sound_set_pitch()`. If you know a sound will never have it's pitch changed with `ma_sound_set_pitch()` or via the doppler effect, you can specify the `MA_SOUND_FLAG_NO_PITCH` flag when initializing the sound for an optimization. By default, sounds and sound groups have spatialization enabled. If you don't ever want to spatialize your sounds, initialize the sound with the `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. The spatialization model is fairly simple and is roughly on feature parity with OpenAL. HRTF and environmental occlusion are not currently supported, but planned for the future. The supported features include: * Sound and listener positioning and orientation with cones * Attenuation models: none, inverse, linear and exponential * Doppler effect Sounds can be faded in and out with `ma_sound_set_fade_in_pcm_frames()`. To check if a sound is currently playing, you can use `ma_sound_is_playing()`. To check if a sound is at the end, use `ma_sound_at_end()`. Looping of a sound can be controlled with `ma_sound_set_looping()`. Use `ma_sound_is_looping()` to check whether or not the sound is looping. 2. Building =========== miniaudio should work cleanly out of the box without the need to download or install any dependencies. See below for platform-specific details. Note that GCC and Clang require `-msse2`, `-mavx2`, etc. for SIMD optimizations. If you get errors about undefined references to `__sync_val_compare_and_swap_8`, `__atomic_load_8`, etc. you need to link with `-latomic`. 2.1. Windows ------------ The Windows build should compile cleanly on all popular compilers without the need to configure any include paths nor link to any libraries. The UWP build may require linking to mmdevapi.lib if you get errors about an unresolved external symbol for `ActivateAudioInterfaceAsync()`. 2.2. macOS and iOS ------------------ The macOS build should compile cleanly without the need to download any dependencies nor link to any libraries or frameworks. The iOS build needs to be compiled as Objective-C and will need to link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling through the command line requires linking to `-lpthread` and `-lm`. Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's notarization process. To fix this there are two options. The first is to use the `MA_NO_RUNTIME_LINKING` option, like so: ```c #ifdef __APPLE__ #define MA_NO_RUNTIME_LINKING #endif #define MINIAUDIO_IMPLEMENTATION #include "miniaudio.h" ``` This will require linking with `-framework CoreFoundation -framework CoreAudio -framework AudioToolbox`. If you get errors about AudioToolbox, try with `-framework AudioUnit` instead. You may get this when using older versions of iOS. Alternatively, if you would rather keep using runtime linking you can add the following to your entitlements.xcent file: ``` com.apple.security.cs.allow-dyld-environment-variables com.apple.security.cs.allow-unsigned-executable-memory ``` See this discussion for more info: https://github.com/mackron/miniaudio/issues/203. 2.3. Linux ---------- The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any development packages. You may need to link with `-latomic` if you're compiling for 32-bit ARM. 2.4. BSD -------- The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses sndio and FreeBSD uses OSS. You may need to link with `-latomic` if you're compiling for 32-bit ARM. 2.5. Android ------------ AAudio is the highest priority backend on Android. This should work out of the box without needing any kind of compiler configuration. Support for AAudio starts with Android 8 which means older versions will fall back to OpenSL|ES which requires API level 16+. There have been reports that the OpenSL|ES backend fails to initialize on some Android based devices due to `dlopen()` failing to open "libOpenSLES.so". If this happens on your platform you'll need to disable run-time linking with `MA_NO_RUNTIME_LINKING` and link with -lOpenSLES. 2.6. Emscripten --------------- The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. You cannot use `-std=c*` compiler flags, nor `-ansi`. You can enable the use of AudioWorkets by defining `MA_ENABLE_AUDIO_WORKLETS` and then compiling with the following options: -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY An example for compiling with AudioWorklet support might look like this: emcc program.c -o bin/program.html -DMA_ENABLE_AUDIO_WORKLETS -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY To run locally, you'll need to use emrun: emrun bin/program.html 2.7.

Definitions ============== This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity in the use of terms throughout the audio space, so this section is intended to clarify how miniaudio uses each term. 3.1. Sample ----------- A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit floating point number. 3.2. Frame / PCM Frame ---------------------- A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 samples, a mono frame is 1 sample, a 5.1 surround sound frame is 6 samples, etc. The terms "frame" and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. If ever miniaudio needs to refer to a compressed frame, such as a FLAC frame, it will always clarify what it's referring to with something like "FLAC frame". 3.3. Channel ------------ A stream of monaural audio that is emitted from an individual speaker in a speaker system, or received from an individual microphone in a microphone system. A stereo stream has two channels (a left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio systems refer to a channel as a complex audio stream that's mixed with other channels to produce the final mix - this is completely different to miniaudio's use of the term "channel" and should not be confused. 3.4. Sample Rate ---------------- The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number of PCM frames that are processed per second. 3.5. Formats ------------ Throughout miniaudio you will see references to different sample formats: +---------------+----------------------------------------+---------------------------+ | Symbol | Description | Range | +---------------+----------------------------------------+---------------------------+ | ma_format_f32 | 32-bit floating point | [-1, 1] | | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | | ma_format_u8 | 8-bit unsigned integer | [0, 255] | +---------------+----------------------------------------+---------------------------+ All formats are native-endian. 4. Data Sources =============== The data source abstraction in miniaudio is used for retrieving audio data from some source. A few examples include `ma_decoder`, `ma_noise` and `ma_waveform`. You will need to be familiar with data sources in order to make sense of some of the higher level concepts in miniaudio. The `ma_data_source` API is a generic interface for reading from a data source. Any object that implements the data source interface can be plugged into any `ma_data_source` function. To read data from a data source: ```c ma_result result; ma_uint64 framesRead; result = ma_data_source_read_pcm_frames(pDataSource, pFramesOut, frameCount, &framesRead); if (result != MA_SUCCESS) { return result; // Failed to read data from the data source. } ``` If you don't need the number of frames that were successfully read you can pass in `NULL` to the `pFramesRead` parameter. If this returns a value less than the number of frames requested it means the end of the file has been reached. `MA_AT_END` will be returned only when the number of frames read is 0. When calling any data source function, with the exception of `ma_data_source_init()` and `ma_data_source_uninit()`, you can pass in any object that implements a data source. For example, you could plug in a decoder like so: ```c ma_result result; ma_uint64 framesRead; ma_decoder decoder; // <-- This would be initialized with `ma_decoder_init_*()`. result = ma_data_source_read_pcm_frames(&decoder, pFramesOut, frameCount, &framesRead); if (result != MA_SUCCESS) { return result; // Failed to read data from the decoder. } ``` If you want to seek forward you can pass in `NULL` to the `pFramesOut` parameter. Alternatively you can use `ma_data_source_seek_pcm_frames()`. To seek to a specific PCM frame: ```c result = ma_data_source_seek_to_pcm_frame(pDataSource, frameIndex); if (result != MA_SUCCESS) { return result; // Failed to seek to PCM frame. } ``` You can retrieve the total length of a data source in PCM frames, but note that some data sources may not have the notion of a length, such as noise and waveforms, and others may just not have a way of determining the length such as some decoders. To retrieve the length: ```c ma_uint64 length; result = ma_data_source_get_length_in_pcm_frames(pDataSource, &length); if (result != MA_SUCCESS) { return result; // Failed to retrieve the length. } ``` Care should be taken when retrieving the length of a data source where the underlying decoder is pulling data from a data stream with an undefined length, such as internet radio or some kind of broadcast. If you do this, `ma_data_source_get_length_in_pcm_frames()` may never return. The current position of the cursor in PCM frames can also be retrieved: ```c ma_uint64 cursor; result = ma_data_source_get_cursor_in_pcm_frames(pDataSource, &cursor); if (result != MA_SUCCESS) { return result; // Failed to retrieve the cursor. } ``` You will often need to know the data format that will be returned after reading. This can be retrieved like so: ```c ma_format format; ma_uint32 channels; ma_uint32 sampleRate; ma_channel channelMap[MA_MAX_CHANNELS]; result = ma_data_source_get_data_format(pDataSource, &format, &channels, &sampleRate, channelMap, MA_MAX_CHANNELS); if (result != MA_SUCCESS) { return result; // Failed to retrieve data format. } ``` If you do not need a specific data format property, just pass in NULL to the respective parameter. There may be cases where you want to implement something like a sound bank where you only want to read data within a certain range of the underlying data. To do this you can use a range: ```c result = ma_data_source_set_range_in_pcm_frames(pDataSource, rangeBegInFrames, rangeEndInFrames); if (result != MA_SUCCESS) { return result; // Failed to set the range. } ``` This is useful if you have a sound bank where many sounds are stored in the same file and you want the data source to only play one of those sub-sounds. Note that once the range is set, everything that takes a position, such as cursors and loop points, should always be relatvie to the start of the range. When the range is set, any previously defined loop point will be reset. Custom loop points can also be used with data sources. By default, data sources will loop after they reach the end of the data source, but if you need to loop at a specific location, you can do the following: ```c result = ma_data_set_loop_point_in_pcm_frames(pDataSource, loopBegInFrames, loopEndInFrames); if (result != MA_SUCCESS) { return result; // Failed to set the loop point. } ``` The loop point is relative to the current range. It's sometimes useful to chain data sources together so that a seamless transition can be achieved. To do this, you can use chaining: ```c ma_decoder decoder1; ma_decoder decoder2; // ... initialize decoders with ma_decoder_init_*() ... result = ma_data_source_set_next(&decoder1, &decoder2); if (result != MA_SUCCESS) { return result; // Failed to set the next data source. } result = ma_data_source_read_pcm_frames(&decoder1, pFramesOut, frameCount, pFramesRead); if (result != MA_SUCCESS) { return result; // Failed to read from the decoder. } ``` In the example above we're using decoders. When reading from a chain, you always want to read from the top level data source in the chain. In the example above, `decoder1` is the top level data source in the chain. When `decoder1` reaches the end, `decoder2` will start seamlessly without any gaps. Note that when looping is enabled, only the current data source will be looped. You can loop the entire chain by linking in a loop like so: ```c ma_data_source_set_next(&decoder1, &decoder2); // decoder1 -> decoder2 ma_data_source_set_next(&decoder2, &decoder1); // decoder2 -> decoder1 (loop back to the start). ``` Note that setting up chaining is not thread safe, so care needs to be taken if you're dynamically changing links while the audio thread is in the middle of reading. Do not use `ma_decoder_seek_to_pcm_frame()` as a means to reuse a data source to play multiple instances of the same sound simultaneously. This can be extremely inefficient depending on the type of data source and can result in glitching due to subtle changes to the state of internal filters. Instead, initialize multiple data sources for each instance. 4.1. Custom Data Sources ------------------------ You can implement a custom data source by implementing the functions in `ma_data_source_vtable`. Your custom object must have `ma_data_source_base` as it's first member: ```c struct my_data_source { ma_data_source_base base; ... }; ``` In your initialization routine, you need to call `ma_data_source_init()` in order to set up the base object (`ma_data_source_base`): ```c static ma_result my_data_source_read(ma_data_source* pDataSource, void* pFramesOut, ma_uint64 frameCount, ma_uint64* pFramesRead) { // Read data here. Output in the same format returned by my_data_source_get_data_format(). } static ma_result my_data_source_seek(ma_data_source* pDataSource, ma_uint64 frameIndex) { // Seek to a specific PCM frame here. Return MA_NOT_IMPLEMENTED if seeking is not supported. } static ma_result my_data_source_get_data_format(ma_data_source* pDataSource, ma_format* pFormat, ma_uint32* pChannels, ma_uint32* pSampleRate, ma_channel* pChannelMap, size_t channelMapCap) { // Return the format of the data here. } static ma_result my_data_source_get_cursor(ma_data_source* pDataSource, ma_uint64* pCursor) { // Retrieve the current position of the cursor here. Return MA_NOT_IMPLEMENTED and set *pCursor to 0 if there is no notion of a cursor. } static ma_result my_data_source_get_length(ma_data_source* pDataSource, ma_uint64* pLength) { // Retrieve the length in PCM frames here. Return MA_NOT_IMPLEMENTED and set *pLength to 0 if there is no notion of a length or if the length is unknown. } static ma_data_source_vtable g_my_data_source_vtable = { my_data_source_read, my_data_source_seek, my_data_source_get_data_format, my_data_source_get_cursor, my_data_source_get_length }; ma_result my_data_source_init(my_data_source* pMyDataSource) { ma_result result; ma_data_source_config baseConfig; baseConfig = ma_data_source_config_init(); baseConfig.vtable = &g_my_data_source_vtable; result = ma_data_source_init(&baseConfig, &pMyDataSource->base); if (result != MA_SUCCESS) { return result; } // ... do the initialization of your custom data source here ... return MA_SUCCESS; } void my_data_source_uninit(my_data_source* pMyDataSource) { // ... do the uninitialization of your custom data source here ... // You must uninitialize the base data source. ma_data_source_uninit(&pMyDataSource->base); } ``` Note that `ma_data_source_init()` and `ma_data_source_uninit()` are never called directly outside of the custom data source. It's up to the custom data source itself to call these within their own init/uninit functions. 5. Engine ========= The `ma_engine` API is a high level API for managing and mixing sounds and effect processing. The `ma_engine` object encapsulates a resource manager and a node graph, both of which will be explained in more detail later. Sounds are called `ma_sound` and are created from an engine. Sounds can be associated with a mixing group called `ma_sound_group` which are also created from the engine. Both `ma_sound` and `ma_sound_group` objects are nodes within the engine's node graph. When the engine is initialized, it will normally create a device internally. If you would rather manage the device yourself, you can do so and just pass a pointer to it via the engine config when you initialize the engine. You can also just use the engine without a device, which again can be configured via the engine config. The most basic way to initialize the engine is with a default config, like so: ```c ma_result result; ma_engine engine; result = ma_engine_init(NULL, &engine); if (result != MA_SUCCESS) { return result; // Failed to initialize the engine. } ``` This will result in the engine initializing a playback device using the operating system's default device. This will be sufficient for many use cases, but if you need more flexibility you'll want to configure the engine with an engine config: ```c ma_result result; ma_engine engine; ma_engine_config engineConfig; engineConfig = ma_engine_config_init(); engineConfig.pDevice = &myDevice; result = ma_engine_init(&engineConfig, &engine); if (result != MA_SUCCESS) { return result; // Failed to initialize the engine. } ``` In the example above we're passing in a pre-initialized device. Since the caller is the one in control of the device's data callback, it's their responsibility to manually call `ma_engine_read_pcm_frames()` from inside their data callback: ```c void playback_data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) { ma_engine_read_pcm_frames(&g_Engine, pOutput, frameCount, NULL); } ``` You can also use the engine independent of a device entirely: ```c ma_result result; ma_engine engine; ma_engine_config engineConfig; engineConfig = ma_engine_config_init(); engineConfig.noDevice = MA_TRUE; engineConfig.channels = 2; // Must be set when not using a device. engineConfig.sampleRate = 48000; // Must be set when not using a device. result = ma_engine_init(&engineConfig, &engine); if (result != MA_SUCCESS) { return result; // Failed to initialize the engine. } ``` Note that when you're not using a device, you must set the channel count and sample rate in the config or else miniaudio won't know what to use (miniaudio will use the device to determine this normally). When not using a device, you need to use `ma_engine_read_pcm_frames()` to process audio data from the engine. This kind of setup is useful if you want to do something like offline processing or want to use a different audio system for playback such as SDL. When a sound is loaded it goes through a resource manager. By default the engine will initialize a resource manager internally, but you can also specify a pre-initialized resource manager: ```c ma_result result; ma_engine engine1; ma_engine engine2; ma_engine_config engineConfig; engineConfig = ma_engine_config_init(); engineConfig.pResourceManager = &myResourceManager; ma_engine_init(&engineConfig, &engine1); ma_engine_init(&engineConfig, &engine2); ``` In this example we are initializing two engines, both of which are sharing the same resource manager. This is especially useful for saving memory when loading the same file across multiple engines. If you were not to use a shared resource manager, each engine instance would use their own which would result in any sounds that are used between both engine's being loaded twice. By using a shared resource manager, it would only be loaded once. Using multiple engine's is useful when you need to output to multiple playback devices, such as in a local multiplayer game where each player is using their own set of headphones. By default an engine will be in a started state. To make it so the engine is not automatically started you can configure it as such: ```c engineConfig.noAutoStart = MA_TRUE; // The engine will need to be started manually. ma_engine_start(&engine); // Later on the engine can be stopped with ma_engine_stop(). ma_engine_stop(&engine); ``` The concept of starting or stopping an engine is only relevant when using the engine with a device. Attempting to start or stop an engine that is not associated with a device will result in `MA_INVALID_OPERATION`. The master volume of the engine can be controlled with `ma_engine_set_volume()` which takes a linear scale, with 0 resulting in silence and anything above 1 resulting in amplification. If you prefer decibel based volume control, use `ma_volume_db_to_linear()` to convert from dB to linear. When a sound is spatialized, it is done so relative to a listener. An engine can be configured to have multiple listeners which can be configured via the config: ```c engineConfig.listenerCount = 2; ``` The maximum number of listeners is restricted to `MA_ENGINE_MAX_LISTENERS`. By default, when a sound is spatialized, it will be done so relative to the closest listener. You can also pin a sound to a specific listener which will be explained later. Listener's have a position, direction, cone, and velocity (for doppler effect). A listener is referenced by an index, the meaning of which is up to the caller (the index is 0 based and cannot go beyond the listener count, minus 1). The position, direction and velocity are all specified in absolute terms: ```c ma_engine_listener_set_position(&engine, listenerIndex, worldPosX, worldPosY, worldPosZ); ``` The direction of the listener represents it's forward vector. The listener's up vector can also be specified and defaults to +1 on the Y axis. ```c ma_engine_listener_set_direction(&engine, listenerIndex, forwardX, forwardY, forwardZ); ma_engine_listener_set_world_up(&engine, listenerIndex, 0, 1, 0); ``` The engine supports directional attenuation. The listener can have a cone the controls how sound is attenuated based on the listener's direction. When a sound is between the inner and outer cones, it will be attenuated between 1 and the cone's outer gain: ```c ma_engine_listener_set_cone(&engine, listenerIndex, innerAngleInRadians, outerAngleInRadians, outerGain); ``` When a sound is inside the inner code, no directional attenuation is applied. When the sound is outside of the outer cone, the attenuation will be set to `outerGain` in the example above. When the sound is in between the inner and outer cones, the attenuation will be interpolated between 1 and the outer gain. The engine's coordinate system follows the OpenGL coordinate system where positive X points right, positive Y points up and negative Z points forward. The simplest and least flexible way to play a sound is like so: ```c ma_engine_play_sound(&engine, "my_sound.wav", pGroup); ``` This is a "fire and forget" style of function. The engine will manage the `ma_sound` object internally. When the sound finishes playing, it'll be put up for recycling. For more flexibility you'll want to initialize a sound object: ```c ma_sound sound; result = ma_sound_init_from_file(&engine, "my_sound.wav", flags, pGroup, NULL, &sound); if (result != MA_SUCCESS) { return result; // Failed to load sound. } ``` Sounds need to be uninitialized with `ma_sound_uninit()`. The example above loads a sound from a file. If the resource manager has been disabled you will not be able to use this function and instead you'll need to initialize a sound directly from a data source: ```c ma_sound sound; result = ma_sound_init_from_data_source(&engine, &dataSource, flags, pGroup, &sound); if (result != MA_SUCCESS) { return result; } ``` Each `ma_sound` object represents a single instance of the sound. If you want to play the same sound multiple times at the same time, you need to initialize a separate `ma_sound` object. For the most flexibility when initializing sounds, use `ma_sound_init_ex()`. This uses miniaudio's standard config/init pattern: ```c ma_sound sound; ma_sound_config soundConfig; soundConfig = ma_sound_config_init(); soundConfig.pFilePath = NULL; // Set this to load from a file path. soundConfig.pDataSource = NULL; // Set this to initialize from an existing data source. soundConfig.pInitialAttachment = &someNodeInTheNodeGraph; soundConfig.initialAttachmentInputBusIndex = 0; soundConfig.channelsIn = 1; soundConfig.channelsOut = 0; // Set to 0 to use the engine's native channel count. result = ma_sound_init_ex(&soundConfig, &sound); if (result != MA_SUCCESS) { return result; } ``` In the example above, the sound is being initialized without a file nor a data source. This is valid, in which case the sound acts as a node in the middle of the node graph. This means you can connect other sounds to this sound and allow it to act like a sound group. Indeed, this is exactly what a `ma_sound_group` is. When loading a sound, you specify a set of flags that control how the sound is loaded and what features are enabled for that sound. When no flags are set, the sound will be fully loaded into memory in exactly the same format as how it's stored on the file system. The resource manager will allocate a block of memory and then load the file directly into it. When reading audio data, it will be decoded dynamically on the fly. In order to save processing time on the audio thread, it might be beneficial to pre-decode the sound. You can do this with the `MA_SOUND_FLAG_DECODE` flag: ```c ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE, pGroup, NULL, &sound); ``` By default, sounds will be loaded synchronously, meaning `ma_sound_init_*()` will not return until the sound has been fully loaded. If this is prohibitive you can instead load sounds asynchronously by specifying the `MA_SOUND_FLAG_ASYNC` flag: ```c ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, NULL, &sound); ``` This will result in `ma_sound_init_*()` returning quickly, but the sound won't yet have been fully loaded. When you start the sound, it won't output anything until some sound is available. The sound will start outputting audio before the sound has been fully decoded when the `MA_SOUND_FLAG_DECODE` is specified. If you need to wait for an asynchronously loaded sound to be fully loaded, you can use a fence. A fence in miniaudio is a simple synchronization mechanism which simply blocks until it's internal counter hit's zero. You can specify a fence like so: ```c ma_result result; ma_fence fence; ma_sound sounds[4]; result = ma_fence_init(&fence); if (result != MA_SUCCESS) { return result; } // Load some sounds asynchronously. for (int iSound = 0; iSound < 4; iSound += 1) { ma_sound_init_from_file(&engine, mySoundFilesPaths[iSound], MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, &fence, &sounds[iSound]); } // ... do some other stuff here in the mean time ... // Wait for all sounds to finish loading. ma_fence_wait(&fence); ``` If loading the entire sound into memory is prohibitive, you can also configure the engine to stream the audio data: ```c ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_STREAM, pGroup, NULL, &sound); ``` When streaming sounds, 2 seconds worth of audio data is stored in memory. Although it should work fine, it's inefficient to use streaming for short sounds. Streaming is useful for things like music tracks in games. When loading a sound from a file path, the engine will reference count the file to prevent it from being loaded if it's already in memory. When you uninitialize a sound, the reference count will be decremented, and if it hits zero, the sound will be unloaded from memory. This reference counting system is not used for streams. The engine will use a 64-bit hash of the file name when comparing file paths which means there's a small chance you might encounter a name collision. If this is an issue, you'll need to use a different name for one of the colliding file paths, or just not load from files and instead load from a data source. You can use `ma_sound_init_copy()` to initialize a copy of another sound. Note, however, that this only works for sounds that were initialized with `ma_sound_init_from_file()` and without the `MA_SOUND_FLAG_STREAM` flag. When you initialize a sound, if you specify a sound group the sound will be attached to that group automatically. If you set it to NULL, it will be automatically attached to the engine's endpoint. If you would instead rather leave the sound unattached by default, you can can specify the `MA_SOUND_FLAG_NO_DEFAULT_ATTACHMENT` flag. This is useful if you want to set up a complex node graph. Sounds are not started by default. To start a sound, use `ma_sound_start()`. Stop a sound with `ma_sound_stop()`. Sounds can have their volume controlled with `ma_sound_set_volume()` in the same way as the engine's master volume. Sounds support stereo panning and pitching. Set the pan with `ma_sound_set_pan()`. Setting the pan to 0 will result in an unpanned sound. Setting it to -1 will shift everything to the left, whereas +1 will shift it to the right. The pitch can be controlled with `ma_sound_set_pitch()`. A larger value will result in a higher pitch. The pitch must be greater than 0. The engine supports 3D spatialization of sounds. By default sounds will have spatialization enabled, but if a sound does not need to be spatialized it's best to disable it. There are two ways to disable spatialization of a sound: ```c // Disable spatialization at initialization time via a flag: ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_NO_SPATIALIZATION, NULL, NULL, &sound); // Dynamically disable or enable spatialization post-initialization: ma_sound_set_spatialization_enabled(&sound, isSpatializationEnabled); ``` By default sounds will be spatialized based on the closest listener. If a sound should always be spatialized relative to a specific listener it can be pinned to one: ```c ma_sound_set_pinned_listener_index(&sound, listenerIndex); ``` Like listeners, sounds have a position. By default, the position of a sound is in absolute space, but it can be changed to be relative to a listener: ```c ma_sound_set_positioning(&sound, ma_positioning_relative); ``` Note that relative positioning of a sound only makes sense if there is either only one listener, or the sound is pinned to a specific listener. To set the position of a sound: ```c ma_sound_set_position(&sound, posX, posY, posZ); ``` The direction works the same way as a listener and represents the sound's forward direction: ```c ma_sound_set_direction(&sound, forwardX, forwardY, forwardZ); ``` Sound's also have a cone for controlling directional attenuation. This works exactly the same as listeners: ```c ma_sound_set_cone(&sound, innerAngleInRadians, outerAngleInRadians, outerGain); ``` The velocity of a sound is used for doppler effect and can be set as such: ```c ma_sound_set_velocity(&sound, velocityX, velocityY, velocityZ); ``` The engine supports different attenuation models which can be configured on a per-sound basis. By default the attenuation model is set to `ma_attenuation_model_inverse` which is the equivalent to OpenAL's `AL_INVERSE_DISTANCE_CLAMPED`. Configure the attenuation model like so: ```c ma_sound_set_attenuation_model(&sound, ma_attenuation_model_inverse); ``` The supported attenuation models include the following: +----------------------------------+----------------------------------------------+ | ma_attenuation_model_none | No distance attenuation. | +----------------------------------+----------------------------------------------+ | ma_attenuation_model_inverse | Equivalent to `AL_INVERSE_DISTANCE_CLAMPED`. | +----------------------------------+----------------------------------------------+ | ma_attenuation_model_linear | Linear attenuation. | +----------------------------------+----------------------------------------------+ | ma_attenuation_model_exponential | Exponential attenuation. | +----------------------------------+----------------------------------------------+ To control how quickly a sound rolls off as it moves away from the listener, you need to configure the rolloff: ```c ma_sound_set_rolloff(&sound, rolloff); ``` You can control the minimum and maximum gain to apply from spatialization: ```c ma_sound_set_min_gain(&sound, minGain); ma_sound_set_max_gain(&sound, maxGain); ``` Likewise, in the calculation of attenuation, you can control the minimum and maximum distances for the attenuation calculation. This is useful if you want to ensure sounds don't drop below a certain volume after the listener moves further away and to have sounds play a maximum volume when the listener is within a certain distance: ```c ma_sound_set_min_distance(&sound, minDistance); ma_sound_set_max_distance(&sound, maxDistance); ``` The engine's spatialization system supports doppler effect. The doppler factor can be configure on a per-sound basis like so: ```c ma_sound_set_doppler_factor(&sound, dopplerFactor); ``` You can fade sounds in and out with `ma_sound_set_fade_in_pcm_frames()` and `ma_sound_set_fade_in_milliseconds()`. Set the volume to -1 to use the current volume as the starting volume: ```c // Fade in over 1 second. ma_sound_set_fade_in_milliseconds(&sound, 0, 1, 1000); // ... sometime later ... // Fade out over 1 second, starting from the current volume. ma_sound_set_fade_in_milliseconds(&sound, -1, 0, 1000); ``` By default sounds will start immediately, but sometimes for timing and synchronization purposes it can be useful to schedule a sound to start or stop: ```c // Start the sound in 1 second from now. ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 1)); // Stop the sound in 2 seconds from now. ma_sound_set_stop_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2)); ``` Note that scheduling a start time still requires an explicit call to `ma_sound_start()` before anything will play. The time is specified in global time which is controlled by the engine. You can get the engine's current time with `ma_engine_get_time_in_pcm_frames()`. The engine's global time is incremented automatically as audio data is read, but it can be reset with `ma_engine_set_time_in_pcm_frames()` in case it needs to be resynchronized for some reason. To determine whether or not a sound is currently playing, use `ma_sound_is_playing()`. This will take the scheduled start and stop times into account. Whether or not a sound should loop can be controlled with `ma_sound_set_looping()`. Sounds will not be looping by default. Use `ma_sound_is_looping()` to determine whether or not a sound is looping. Use `ma_sound_at_end()` to determine whether or not a sound is currently at the end. For a looping sound this should never return true. Alternatively, you can configure a callback that will be fired when the sound reaches the end. Note that the callback is fired from the audio thread which means you cannot be uninitializing sound from the callback. To set the callback you can use `ma_sound_set_end_callback()`. Alternatively, if you're using `ma_sound_init_ex()`, you can pass it into the config like so: ```c soundConfig.endCallback = my_end_callback; soundConfig.pEndCallbackUserData = pMyEndCallbackUserData; ``` The end callback is declared like so: ```c void my_end_callback(void* pUserData, ma_sound* pSound) { ... } ``` Internally a sound wraps around a data source. Some APIs exist to control the underlying data source, mainly for convenience: ```c ma_sound_seek_to_pcm_frame(&sound, frameIndex); ma_sound_get_data_format(&sound, &format, &channels, &sampleRate, pChannelMap, channelMapCapacity); ma_sound_get_cursor_in_pcm_frames(&sound, &cursor); ma_sound_get_length_in_pcm_frames(&sound, &length); ``` Sound groups have the same API as sounds, only they are called `ma_sound_group`, and since they do not have any notion of a data source, anything relating to a data source is unavailable. Internally, sound data is loaded via the `ma_decoder` API which means by default it only supports file formats that have built-in support in miniaudio. You can extend this to support any kind of file format through the use of custom decoders. To do this you'll need to use a self-managed resource manager and configure it appropriately. See the "Resource Management" section below for details on how to set this up. 6. Resource Management ====================== Many programs will want to manage sound resources for things such as reference counting and streaming. This is supported by miniaudio via the `ma_resource_manager` API. The resource manager is mainly responsible for the following: * Loading of sound files into memory with reference counting. * Streaming of sound data. When loading a sound file, the resource manager will give you back a `ma_data_source` compatible object called `ma_resource_manager_data_source`. This object can be passed into any `ma_data_source` API which is how you can read and seek audio data. When loading a sound file, you specify whether or not you want the sound to be fully loaded into memory (and optionally pre-decoded) or streamed. When loading into memory, you can also specify whether or not you want the data to be loaded asynchronously. The example below is how you can initialize a resource manager using it's default configuration: ```c ma_resource_manager_config config; ma_resource_manager resourceManager; config = ma_resource_manager_config_init(); result = ma_resource_manager_init(&config, &resourceManager); if (result != MA_SUCCESS) { ma_device_uninit(&device); printf("Failed to initialize the resource manager."); return -1; } ``` You can configure the format, channels and sample rate of the decoded audio data. By default it will use the file's native data format, but you can configure it to use a consistent format. This is useful for offloading the cost of data conversion to load time rather than dynamically converting at mixing time. To do this, you configure the decoded format, channels and sample rate like the code below: ```c config = ma_resource_manager_config_init(); config.decodedFormat = device.playback.format; config.decodedChannels = device.playback.channels; config.decodedSampleRate = device.sampleRate; ``` In the code above, the resource manager will be configured so that any decoded audio data will be pre-converted at load time to the device's native data format. If instead you used defaults and the data format of the file did not match the device's data format, you would need to convert the data at mixing time which may be prohibitive in high-performance and large scale scenarios like games. Internally the resource manager uses the `ma_decoder` API to load sounds. This means by default it only supports decoders that are built into miniaudio. It's possible to support additional encoding formats through the use of custom decoders. To do so, pass in your `ma_decoding_backend_vtable` vtables into the resource manager config: ```c ma_decoding_backend_vtable* pCustomBackendVTables[] = { &g_ma_decoding_backend_vtable_libvorbis, &g_ma_decoding_backend_vtable_libopus }; ... resourceManagerConfig.ppCustomDecodingBackendVTables = pCustomBackendVTables; resourceManagerConfig.customDecodingBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); resourceManagerConfig.pCustomDecodingBackendUserData = NULL; ``` This system can allow you to support any kind of file format. See the "Decoding" section for details on how to implement custom decoders. The miniaudio repository includes examples for Opus via libopus and libopusfile and Vorbis via libvorbis and libvorbisfile. Asynchronicity is achieved via a job system. When an operation needs to be performed, such as the decoding of a page, a job will be posted to a queue which will then be processed by a job thread. By default there will be only one job thread running, but this can be configured, like so: ```c config = ma_resource_manager_config_init(); config.jobThreadCount = MY_JOB_THREAD_COUNT; ``` By default job threads are managed internally by the resource manager, however you can also self manage your job threads if, for example, you want to integrate the job processing into your existing job infrastructure, or if you simply don't like the way the resource manager does it. To do this, just set the job thread count to 0 and process jobs manually. To process jobs, you first need to retrieve a job using `ma_resource_manager_next_job()` and then process it using `ma_job_process()`: ```c config = ma_resource_manager_config_init(); config.jobThreadCount = 0; // Don't manage any job threads internally. config.flags = MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING; // Optional. Makes `ma_resource_manager_next_job()` non-blocking. // ... Initialize your custom job threads ... void my_custom_job_thread(...) { for (;;) { ma_job job; ma_result result = ma_resource_manager_next_job(pMyResourceManager, &job); if (result != MA_SUCCESS) { if (result == MA_NO_DATA_AVAILABLE) { // No jobs are available. Keep going. Will only get this if the resource manager was initialized // with MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING. continue; } else if (result == MA_CANCELLED) { // MA_JOB_TYPE_QUIT was posted. Exit. break; } else { // Some other error occurred. break; } } ma_job_process(&job); } } ``` In the example above, the `MA_JOB_TYPE_QUIT` event is the used as the termination indicator, but you can use whatever you would like to terminate the thread. The call to `ma_resource_manager_next_job()` is blocking by default, but can be configured to be non-blocking by initializing the resource manager with the `MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING` configuration flag. Note that the `MA_JOB_TYPE_QUIT` will never be removed from the job queue. This is to give every thread the opportunity to catch the event and terminate naturally. When loading a file, it's sometimes convenient to be able to customize how files are opened and read instead of using standard `fopen()`, `fclose()`, etc. which is what miniaudio will use by default. This can be done by setting `pVFS` member of the resource manager's config: ```c // Initialize your custom VFS object. See documentation for VFS for information on how to do this. my_custom_vfs vfs = my_custom_vfs_init(); config = ma_resource_manager_config_init(); config.pVFS = &vfs; ``` This is particularly useful in programs like games where you want to read straight from an archive rather than the normal file system. If you do not specify a custom VFS, the resource manager will use the operating system's normal file operations. To load a sound file and create a data source, call `ma_resource_manager_data_source_init()`. When loading a sound you need to specify the file path and options for how the sounds should be loaded. By default a sound will be loaded synchronously. The returned data source is owned by the caller which means the caller is responsible for the allocation and freeing of the data source. Below is an example for initializing a data source: ```c ma_resource_manager_data_source dataSource; ma_result result = ma_resource_manager_data_source_init(pResourceManager, pFilePath, flags, &dataSource); if (result != MA_SUCCESS) { // Error. } // ... // A ma_resource_manager_data_source object is compatible with the `ma_data_source` API. To read data, just call // the `ma_data_source_read_pcm_frames()` like you would with any normal data source. result = ma_data_source_read_pcm_frames(&dataSource, pDecodedData, frameCount, &framesRead); if (result != MA_SUCCESS) { // Failed to read PCM frames. } // ... ma_resource_manager_data_source_uninit(pResourceManager, &dataSource); ``` The `flags` parameter specifies how you want to perform loading of the sound file. It can be a combination of the following flags: ``` MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_WAIT_INIT ``` When no flags are specified (set to 0), the sound will be fully loaded into memory, but not decoded, meaning the raw file data will be stored in memory, and then dynamically decoded when `ma_data_source_read_pcm_frames()` is called. To instead decode the audio data before storing it in memory, use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` flag. By default, the sound file will be loaded synchronously, meaning `ma_resource_manager_data_source_init()` will only return after the entire file has been loaded. This is good for simplicity, but can be prohibitively slow. You can instead load the sound asynchronously using the `MA_RESOURCE_MANAGER_DATA_SOURCE_ASYNC` flag. This will result in `ma_resource_manager_data_source_init()` returning quickly, but no data will be returned by `ma_data_source_read_pcm_frames()` until some data is available. When no data is available because the asynchronous decoding hasn't caught up, `MA_BUSY` will be returned by `ma_data_source_read_pcm_frames()`. For large sounds, it's often prohibitive to store the entire file in memory. To mitigate this, you can instead stream audio data which you can do by specifying the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. When streaming, data will be decoded in 1 second pages. When a new page needs to be decoded, a job will be posted to the job queue and then subsequently processed in a job thread. For in-memory sounds, reference counting is used to ensure the data is loaded only once. This means multiple calls to `ma_resource_manager_data_source_init()` with the same file path will result in the file data only being loaded once. Each call to `ma_resource_manager_data_source_init()` must be matched up with a call to `ma_resource_manager_data_source_uninit()`. Sometimes it can be useful for a program to register self-managed raw audio data and associate it with a file path. Use the `ma_resource_manager_register_*()` and `ma_resource_manager_unregister_*()` APIs to do this. `ma_resource_manager_register_decoded_data()` is used to associate a pointer to raw, self-managed decoded audio data in the specified data format with the specified name. Likewise, `ma_resource_manager_register_encoded_data()` is used to associate a pointer to raw self-managed encoded audio data (the raw file data) with the specified name. Note that these names need not be actual file paths. When `ma_resource_manager_data_source_init()` is called (without the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag), the resource manager will look for these explicitly registered data buffers and, if found, will use it as the backing data for the data source. Note that the resource manager does *not* make a copy of this data so it is up to the caller to ensure the pointer stays valid for it's lifetime. Use `ma_resource_manager_unregister_data()` to unregister the self-managed data. You can also use `ma_resource_manager_register_file()` and `ma_resource_manager_unregister_file()` to register and unregister a file. It does not make sense to use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag with a self-managed data pointer. 6.1. Asynchronous Loading and Synchronization --------------------------------------------- When loading asynchronously, it can be useful to poll whether or not loading has finished. Use `ma_resource_manager_data_source_result()` to determine this. For in-memory sounds, this will return `MA_SUCCESS` when the file has been *entirely* decoded. If the sound is still being decoded, `MA_BUSY` will be returned. Otherwise, some other error code will be returned if the sound failed to load. For streaming data sources, `MA_SUCCESS` will be returned when the first page has been decoded and the sound is ready to be played. If the first page is still being decoded, `MA_BUSY` will be returned. Otherwise, some other error code will be returned if the sound failed to load. In addition to polling, you can also use a simple synchronization object called a "fence" to wait for asynchronously loaded sounds to finish. This is called `ma_fence`. The advantage to using a fence is that it can be used to wait for a group of sounds to finish loading rather than waiting for sounds on an individual basis. There are two stages to loading a sound: * Initialization of the internal decoder; and * Completion of decoding of the file (the file is fully decoded) You can specify separate fences for each of the different stages. Waiting for the initialization of the internal decoder is important for when you need to know the sample format, channels and sample rate of the file. The example below shows how you could use a fence when loading a number of sounds: ```c // This fence will be released when all sounds are finished loading entirely. ma_fence fence; ma_fence_init(&fence); // This will be passed into the initialization routine for each sound. ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); notifications.done.pFence = &fence; // Now load a bunch of sounds: for (iSound = 0; iSound < soundCount; iSound += 1) { ma_resource_manager_data_source_init(pResourceManager, pSoundFilePaths[iSound], flags, ¬ifications, &pSoundSources[iSound]); } // ... DO SOMETHING ELSE WHILE SOUNDS ARE LOADING ... // Wait for loading of sounds to finish. ma_fence_wait(&fence); ``` In the example above we used a fence for waiting until the entire file has been fully decoded. If you only need to wait for the initialization of the internal decoder to complete, you can use the `init` member of the `ma_resource_manager_pipeline_notifications` object: ```c notifications.init.pFence = &fence; ``` If a fence is not appropriate for your situation, you can instead use a callback that is fired on an individual sound basis. This is done in a very similar way to fences: ```c typedef struct { ma_async_notification_callbacks cb; void* pMyData; } my_notification; void my_notification_callback(ma_async_notification* pNotification) { my_notification* pMyNotification = (my_notification*)pNotification; // Do something in response to the sound finishing loading. } ... my_notification myCallback; myCallback.cb.onSignal = my_notification_callback; myCallback.pMyData = pMyData; ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); notifications.done.pNotification = &myCallback; ma_resource_manager_data_source_init(pResourceManager, "my_sound.wav", flags, ¬ifications, &mySound); ``` In the example above we just extend the `ma_async_notification_callbacks` object and pass an instantiation into the `ma_resource_manager_pipeline_notifications` in the same way as we did with the fence, only we set `pNotification` instead of `pFence`. You can set both of these at the same time and they should both work as expected. If using the `pNotification` system, you need to ensure your `ma_async_notification_callbacks` object stays valid. 6.2. Resource Manager Implementation Details -------------------------------------------- Resources are managed in two main ways: * By storing the entire sound inside an in-memory buffer (referred to as a data buffer) * By streaming audio data on the fly (referred to as a data stream) A resource managed data source (`ma_resource_manager_data_source`) encapsulates a data buffer or data stream, depending on whether or not the data source was initialized with the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. If so, it will make use of a `ma_resource_manager_data_stream` object. Otherwise it will use a `ma_resource_manager_data_buffer` object. Both of these objects are data sources which means they can be used with any `ma_data_source_*()` API. Another major feature of the resource manager is the ability to asynchronously decode audio files. This relieves the audio thread of time-consuming decoding which can negatively affect scalability due to the audio thread needing to complete it's work extremely quickly to avoid glitching. Asynchronous decoding is achieved through a job system. There is a central multi-producer, multi-consumer, fixed-capacity job queue. When some asynchronous work needs to be done, a job is posted to the queue which is then read by a job thread. The number of job threads can be configured for improved scalability, and job threads can all run in parallel without needing to worry about the order of execution (how this is achieved is explained below). When a sound is being loaded asynchronously, playback can begin before the sound has been fully decoded. This enables the application to start playback of the sound quickly, while at the same time allowing to resource manager to keep loading in the background. Since there may be less threads than the number of sounds being loaded at a given time, a simple scheduling system is used to keep decoding time balanced and fair. The resource manager solves this by splitting decoding into chunks called pages. By default, each page is 1 second long. When a page has been decoded, a new job will be posted to start decoding the next page. By dividing up decoding into pages, an individual sound shouldn't ever delay every other sound from having their first page decoded. Of course, when loading many sounds at the same time, there will always be an amount of time required to process jobs in the queue so in heavy load situations there will still be some delay. To determine if a data source is ready to have some frames read, use `ma_resource_manager_data_source_get_available_frames()`. This will return the number of frames available starting from the current position. 6.2.1. Job Queue ---------------- The resource manager uses a job queue which is multi-producer, multi-consumer, and fixed-capacity. This job queue is not currently lock-free, and instead uses a spinlock to achieve thread-safety. Only a fixed number of jobs can be allocated and inserted into the queue which is done through a lock-free data structure for allocating an index into a fixed sized array, with reference counting for mitigation of the ABA problem. The reference count is 32-bit. For many types of jobs it's important that they execute in a specific order. In these cases, jobs are executed serially. For the resource manager, serial execution of jobs is only required on a per-object basis (per data buffer or per data stream). Each of these objects stores an execution counter. When a job is posted it is associated with an execution counter. When the job is processed, it checks if the execution counter of the job equals the execution counter of the owning object and if so, processes the job. If the counters are not equal, the job will be posted back onto the job queue for later processing. When the job finishes processing the execution order of the main object is incremented. This system means the no matter how many job threads are executing, decoding of an individual sound will always get processed serially. The advantage to having multiple threads comes into play when loading multiple sounds at the same time. The resource manager's job queue is not 100% lock-free and will use a spinlock to achieve thread-safety for a very small section of code. This is only relevant when the resource manager uses more than one job thread. If only using a single job thread, which is the default, the lock should never actually wait in practice. The amount of time spent locking should be quite short, but it's something to be aware of for those who have pedantic lock-free requirements and need to use more than one job thread. There are plans to remove this lock in a future version. In addition, posting a job will release a semaphore, which on Win32 is implemented with `ReleaseSemaphore` and on POSIX platforms via a condition variable: ```c pthread_mutex_lock(&pSemaphore->lock); { pSemaphore->value += 1; pthread_cond_signal(&pSemaphore->cond); } pthread_mutex_unlock(&pSemaphore->lock); ``` Again, this is relevant for those with strict lock-free requirements in the audio thread. To avoid this, you can use non-blocking mode (via the `MA_JOB_QUEUE_FLAG_NON_BLOCKING` flag) and implement your own job processing routine (see the "Resource Manager" section above for details on how to do this). 6.2.2. Data Buffers ------------------- When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag is excluded at initialization time, the resource manager will try to load the data into an in-memory data buffer. Before doing so, however, it will first check if the specified file is already loaded. If so, it will increment a reference counter and just use the already loaded data. This saves both time and memory. When the data buffer is uninitialized, the reference counter will be decremented. If the counter hits zero, the file will be unloaded. This is a detail to keep in mind because it could result in excessive loading and unloading of a sound. For example, the following sequence will result in a file be loaded twice, once after the other: ```c ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer0); // Refcount = 1. Initial load. ma_resource_manager_data_source_uninit(pResourceManager, &myDataBuffer0); // Refcount = 0. Unloaded. ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer1); // Refcount = 1. Reloaded because previous uninit() unloaded it. ma_resource_manager_data_source_uninit(pResourceManager, &myDataBuffer1); // Refcount = 0. Unloaded. ``` A binary search tree (BST) is used for storing data buffers as it has good balance between efficiency and simplicity. The key of the BST is a 64-bit hash of the file path that was passed into `ma_resource_manager_data_source_init()`. The advantage of using a hash is that it saves memory over storing the entire path, has faster comparisons, and results in a mostly balanced BST due to the random nature of the hash. The disadvantages are that file names are case-sensitive and there's a small chance of name collisions. If case-sensitivity is an issue, you should normalize your file names to upper- or lower-case before initializing your data sources. If name collisions become an issue, you'll need to change the name of one of the colliding names or just not use the resource manager. When a sound file has not already been loaded and the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag is excluded, the file will be decoded synchronously by the calling thread. There are two options for controlling how the audio is stored in the data buffer - encoded or decoded. When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` option is excluded, the raw file data will be stored in memory. Otherwise the sound will be decoded before storing it in memory. Synchronous loading is a very simple and standard process of simply adding an item to the BST, allocating a block of memory and then decoding (if `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` is specified). When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag is specified, loading of the data buffer is done asynchronously. In this case, a job is posted to the queue to start loading and then the function immediately returns, setting an internal result code to `MA_BUSY`. This result code is returned when the program calls `ma_resource_manager_data_source_result()`. When decoding has fully completed `MA_SUCCESS` will be returned. This can be used to know if loading has fully completed. When loading asynchronously, a single job is posted to the queue of the type `MA_JOB_TYPE_RESOURCE_MANAGER_LOAD_DATA_BUFFER_NODE`. This involves making a copy of the file path and associating it with job. When the job is processed by the job thread, it will first load the file using the VFS associated with the resource manager. When using a custom VFS, it's important that it be completely thread-safe because it will be used from one or more job threads at the same time. Individual files should only ever be accessed by one thread at a time, however. After opening the file via the VFS, the job will determine whether or not the file is being decoded. If not, it simply allocates a block of memory and loads the raw file contents into it and returns. On the other hand, when the file is being decoded, it will first allocate a decoder on the heap and initialize it. Then it will check if the length of the file is known. If so it will allocate a block of memory to store the decoded output and initialize it to silence. If the size is unknown, it will allocate room for one page. After memory has been allocated, the first page will be decoded. If the sound is shorter than a page, the result code will be set to `MA_SUCCESS` and the completion event will be signalled and loading is now complete. If, however, there is more to decode, a job with the code `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` is posted. This job will decode the next page and perform the same process if it reaches the end. If there is more to decode, the job will post another `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` job which will keep on happening until the sound has been fully decoded. For sounds of an unknown length, each page will be linked together as a linked list. Internally this is implemented via the `ma_paged_audio_buffer` object. 6.2.3. Data Streams ------------------- Data streams only ever store two pages worth of data for each instance. They are most useful for large sounds like music tracks in games that would consume too much memory if fully decoded in memory. After every frame from a page has been read, a job will be posted to load the next page which is done from the VFS. For data streams, the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag will determine whether or not initialization of the data source waits until the two pages have been decoded. When unset, `ma_resource_manager_data_source_init()` will wait until the two pages have been loaded, otherwise it will return immediately. When frames are read from a data stream using `ma_resource_manager_data_source_read_pcm_frames()`, `MA_BUSY` will be returned if there are no frames available. If there are some frames available, but less than the number requested, `MA_SUCCESS` will be returned, but the actual number of frames read will be less than the number requested. Due to the asynchronous nature of data streams, seeking is also asynchronous. If the data stream is in the middle of a seek, `MA_BUSY` will be returned when trying to read frames. When `ma_resource_manager_data_source_read_pcm_frames()` results in a page getting fully consumed a job is posted to load the next page. This will be posted from the same thread that called `ma_resource_manager_data_source_read_pcm_frames()`. Data streams are uninitialized by posting a job to the queue, but the function won't return until that job has been processed. The reason for this is that the caller owns the data stream object and therefore miniaudio needs to ensure everything completes before handing back control to the caller. Also, if the data stream is uninitialized while pages are in the middle of decoding, they must complete before destroying any underlying object and the job system handles this cleanly. Note that when a new page needs to be loaded, a job will be posted to the resource manager's job thread from the audio thread. You must keep in mind the details mentioned in the "Job Queue" section above regarding locking when posting an event if you require a strictly lock-free audio thread. 7. Node Graph ============= miniaudio's routing infrastructure follows a node graph paradigm. The idea is that you create a node whose outputs are attached to inputs of another node, thereby creating a graph. There are different types of nodes, with each node in the graph processing input data to produce output, which is then fed through the chain. Each node in the graph can apply their own custom effects. At the start of the graph will usually be one or more data source nodes which have no inputs and instead pull their data from a data source. At the end of the graph is an endpoint which represents the end of the chain and is where the final output is ultimately extracted from. Each node has a number of input buses and a number of output buses. An output bus from a node is attached to an input bus of another. Multiple nodes can connect their output buses to another node's input bus, in which case their outputs will be mixed before processing by the node. Below is a diagram that illustrates a hypothetical node graph setup: ``` >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Data flows left to right >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> +---------------+ +-----------------+ | Data Source 1 =----+ +----------+ +----= Low Pass Filter =----+ +---------------+ | | =----+ +-----------------+ | +----------+ +----= Splitter | +----= ENDPOINT | +---------------+ | | =----+ +-----------------+ | +----------+ | Data Source 2 =----+ +----------+ +----= Echo / Delay =----+ +---------------+ +-----------------+ ``` In the above graph, it starts with two data sources whose outputs are attached to the input of a splitter node. It's at this point that the two data sources are mixed. After mixing, the splitter performs it's processing routine and produces two outputs which is simply a duplication of the input stream. One output is attached to a low pass filter, whereas the other output is attached to a echo/delay. The outputs of the the low pass filter and the echo are attached to the endpoint, and since they're both connected to the same input bus, they'll be mixed. Each input bus must be configured to accept the same number of channels, but the number of channels used by input buses can be different to the number of channels for output buses in which case miniaudio will automatically convert the input data to the output channel count before processing. The number of channels of an output bus of one node must match the channel count of the input bus it's attached to. The channel counts cannot be changed after the node has been initialized. If you attempt to attach an output bus to an input bus with a different channel count, attachment will fail. To use a node graph, you first need to initialize a `ma_node_graph` object. This is essentially a container around the entire graph. The `ma_node_graph` object is required for some thread-safety issues which will be explained later. A `ma_node_graph` object is initialized using miniaudio's standard config/init system: ```c ma_node_graph_config nodeGraphConfig = ma_node_graph_config_init(myChannelCount); result = ma_node_graph_init(&nodeGraphConfig, NULL, &nodeGraph); // Second parameter is a pointer to allocation callbacks. if (result != MA_SUCCESS) { // Failed to initialize node graph. } ``` When you initialize the node graph, you're specifying the channel count of the endpoint. The endpoint is a special node which has one input bus and one output bus, both of which have the same channel count, which is specified in the config. Any nodes that connect directly to the endpoint must be configured such that their output buses have the same channel count. When you read audio data from the node graph, it'll have the channel count you specified in the config. To read data from the graph: ```c ma_uint32 framesRead; result = ma_node_graph_read_pcm_frames(&nodeGraph, pFramesOut, frameCount, &framesRead); if (result != MA_SUCCESS) { // Failed to read data from the node graph. } ``` When you read audio data, miniaudio starts at the node graph's endpoint node which then pulls in data from it's input attachments, which in turn recursively pull in data from their inputs, and so on. At the start of the graph there will be some kind of data source node which will have zero inputs and will instead read directly from a data source. The base nodes don't literally need to read from a `ma_data_source` object, but they will always have some kind of underlying object that sources some kind of audio. The `ma_data_source_node` node can be used to read from a `ma_data_source`. Data is always in floating-point format and in the number of channels you specified when the graph was initialized. The sample rate is defined by the underlying data sources. It's up to you to ensure they use a consistent and appropriate sample rate. The `ma_node` API is designed to allow custom nodes to be implemented with relative ease, but miniaudio includes a few stock nodes for common functionality. This is how you would initialize a node which reads directly from a data source (`ma_data_source_node`) which is an example of one of the stock nodes that comes with miniaudio: ```c ma_data_source_node_config config = ma_data_source_node_config_init(pMyDataSource); ma_data_source_node dataSourceNode; result = ma_data_source_node_init(&nodeGraph, &config, NULL, &dataSourceNode); if (result != MA_SUCCESS) { // Failed to create data source node. } ``` The data source node will use the output channel count to determine the channel count of the output bus. There will be 1 output bus and 0 input buses (data will be drawn directly from the data source). The data source must output to floating-point (`ma_format_f32`) or else an error will be returned from `ma_data_source_node_init()`. By default the node will not be attached to the graph. To do so, use `ma_node_attach_output_bus()`: ```c result = ma_node_attach_output_bus(&dataSourceNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); if (result != MA_SUCCESS) { // Failed to attach node. } ``` The code above connects the data source node directly to the endpoint. Since the data source node has only a single output bus, the index will always be 0. Likewise, the endpoint only has a single input bus which means the input bus index will also always be 0. To detach a specific output bus, use `ma_node_detach_output_bus()`. To detach all output buses, use `ma_node_detach_all_output_buses()`. If you want to just move the output bus from one attachment to another, you do not need to detach first. You can just call `ma_node_attach_output_bus()` and it'll deal with it for you. Less frequently you may want to create a specialized node. This will be a node where you implement your own processing callback to apply a custom effect of some kind. This is similar to initializing one of the stock node types, only this time you need to specify a pointer to a vtable containing a pointer to the processing function and the number of input and output buses. Example: ```c static void my_custom_node_process_pcm_frames(ma_node* pNode, const float** ppFramesIn, ma_uint32* pFrameCountIn, float** ppFramesOut, ma_uint32* pFrameCountOut) { // Do some processing of ppFramesIn (one stream of audio data per input bus) const float* pFramesIn_0 = ppFramesIn[0]; // Input bus @ index 0. const float* pFramesIn_1 = ppFramesIn[1]; // Input bus @ index 1. float* pFramesOut_0 = ppFramesOut[0]; // Output bus @ index 0. // Do some processing. On input, `pFrameCountIn` will be the number of input frames in each // buffer in `ppFramesIn` and `pFrameCountOut` will be the capacity of each of the buffers // in `ppFramesOut`. On output, `pFrameCountIn` should be set to the number of input frames // your node consumed and `pFrameCountOut` should be set the number of output frames that // were produced. // // You should process as many frames as you can. If your effect consumes input frames at the // same rate as output frames (always the case, unless you're doing resampling), you need // only look at `ppFramesOut` and process that exact number of frames. If you're doing // resampling, you'll need to be sure to set both `pFrameCountIn` and `pFrameCountOut` // properly. } static ma_node_vtable my_custom_node_vtable = { my_custom_node_process_pcm_frames, // The function that will be called to process your custom node. This is where you'd implement your effect processing. NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. 2, // 2 input buses. 1, // 1 output bus. 0 // Default flags. }; ... // Each bus needs to have a channel count specified. To do this you need to specify the channel // counts in an array and then pass that into the node config. ma_uint32 inputChannels[2]; // Equal in size to the number of input channels specified in the vtable. ma_uint32 outputChannels[1]; // Equal in size to the number of output channels specified in the vtable. inputChannels[0] = channelsIn; inputChannels[1] = channelsIn; outputChannels[0] = channelsOut; ma_node_config nodeConfig = ma_node_config_init(); nodeConfig.vtable = &my_custom_node_vtable; nodeConfig.pInputChannels = inputChannels; nodeConfig.pOutputChannels = outputChannels; ma_node_base node; result = ma_node_init(&nodeGraph, &nodeConfig, NULL, &node); if (result != MA_SUCCESS) { // Failed to initialize node. } ``` When initializing a custom node, as in the code above, you'll normally just place your vtable in static space. The number of input and output buses are specified as part of the vtable. If you need a variable number of buses on a per-node bases, the vtable should have the relevant bus count set to `MA_NODE_BUS_COUNT_UNKNOWN`. In this case, the bus count should be set in the node config: ```c static ma_node_vtable my_custom_node_vtable = { my_custom_node_process_pcm_frames, // The function that will be called process your custom node. This is where you'd implement your effect processing. NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. MA_NODE_BUS_COUNT_UNKNOWN, // The number of input buses is determined on a per-node basis. 1, // 1 output bus. 0 // Default flags. }; ... ma_node_config nodeConfig = ma_node_config_init(); nodeConfig.vtable = &my_custom_node_vtable; nodeConfig.inputBusCount = myBusCount; // <-- Since the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN, the input bus count should be set here. nodeConfig.pInputChannels = inputChannels; // <-- Make sure there are nodeConfig.inputBusCount elements in this array. nodeConfig.pOutputChannels = outputChannels; // <-- The vtable specifies 1 output bus, so there must be 1 element in this array. ``` In the above example it's important to never set the `inputBusCount` and `outputBusCount` members to anything other than their defaults if the vtable specifies an explicit count. They can only be set if the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN in the relevant bus count. Most often you'll want to create a structure to encapsulate your node with some extra data. You need to make sure the `ma_node_base` object is your first member of the structure: ```c typedef struct { ma_node_base base; // <-- Make sure this is always the first member. float someCustomData; } my_custom_node; ``` By doing this, your object will be compatible with all `ma_node` APIs and you can attach it to the graph just like any other node. In the custom processing callback (`my_custom_node_process_pcm_frames()` in the example above), the number of channels for each bus is what was specified by the config when the node was initialized with `ma_node_init()`. In addition, all attachments to each of the input buses will have been pre-mixed by miniaudio. The config allows you to specify different channel counts for each individual input and output bus. It's up to the effect to handle it appropriate, and if it can't, return an error in it's initialization routine. Custom nodes can be assigned some flags to describe their behaviour. These are set via the vtable and include the following: +-----------------------------------------+---------------------------------------------------+ | Flag Name | Description | +-----------------------------------------+---------------------------------------------------+ | MA_NODE_FLAG_PASSTHROUGH | Useful for nodes that do not do any kind of audio | | | processing, but are instead used for tracking | | | time, handling events, etc. Also used by the | | | internal endpoint node. It reads directly from | | | the input bus to the output bus. Nodes with this | | | flag must have exactly 1 input bus and 1 output | | | bus, and both buses must have the same channel | | | counts. | +-----------------------------------------+---------------------------------------------------+ | MA_NODE_FLAG_CONTINUOUS_PROCESSING | Causes the processing callback to be called even | | | when no data is available to be read from input | | | attachments. When a node has at least one input | | | bus, but there are no inputs attached or the | | | inputs do not deliver any data, the node's | | | processing callback will not get fired. This flag | | | will make it so the callback is always fired | | | regardless of whether or not any input data is | | | received. This is useful for effects like | | | echos where there will be a tail of audio data | | | that still needs to be processed even when the | | | original data sources have reached their ends. It | | | may also be useful for nodes that must always | | | have their processing callback fired when there | | | are no inputs attached. | +-----------------------------------------+---------------------------------------------------+ | MA_NODE_FLAG_ALLOW_NULL_INPUT | Used in conjunction with | | | `MA_NODE_FLAG_CONTINUOUS_PROCESSING`. When this | | | is set, the `ppFramesIn` parameter of the | | | processing callback will be set to NULL when | | | there are no input frames are available. When | | | this is unset, silence will be posted to the | | | processing callback. | +-----------------------------------------+---------------------------------------------------+ | MA_NODE_FLAG_DIFFERENT_PROCESSING_RATES | Used to tell miniaudio that input and output | | | frames are processed at different rates. You | | | should set this for any nodes that perform | | | resampling. | +-----------------------------------------+---------------------------------------------------+ | MA_NODE_FLAG_SILENT_OUTPUT | Used to tell miniaudio that a node produces only | | | silent output. This is useful for nodes where you | | | don't want the output to contribute to the final | | | mix. An example might be if you want split your | | | stream and have one branch be output to a file. | | | When using this flag, you should avoid writing to | | | the output buffer of the node's processing | | | callback because miniaudio will ignore it anyway. | +-----------------------------------------+---------------------------------------------------+ If you need to make a copy of an audio stream for effect processing you can use a splitter node called `ma_splitter_node`. This takes has 1 input bus and splits the stream into 2 output buses. You can use it like this: ```c ma_splitter_node_config splitterNodeConfig = ma_splitter_node_config_init(channels); ma_splitter_node splitterNode; result = ma_splitter_node_init(&nodeGraph, &splitterNodeConfig, NULL, &splitterNode); if (result != MA_SUCCESS) { // Failed to create node. } // Attach your output buses to two different input buses (can be on two different nodes). ma_node_attach_output_bus(&splitterNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); // Attach directly to the endpoint. ma_node_attach_output_bus(&splitterNode, 1, &myEffectNode, 0); // Attach to input bus 0 of some effect node. ``` The volume of an output bus can be configured on a per-bus basis: ```c ma_node_set_output_bus_volume(&splitterNode, 0, 0.5f); ma_node_set_output_bus_volume(&splitterNode, 1, 0.5f); ``` In the code above we're using the splitter node from before and changing the volume of each of the copied streams. You can start and stop a node with the following: ```c ma_node_set_state(&splitterNode, ma_node_state_started); // The default state. ma_node_set_state(&splitterNode, ma_node_state_stopped); ``` By default the node is in a started state, but since it won't be connected to anything won't actually be invoked by the node graph until it's connected. When you stop a node, data will not be read from any of it's input connections. You can use this property to stop a group of sounds atomically. You can configure the initial state of a node in it's config: ```c nodeConfig.initialState = ma_node_state_stopped; ``` Note that for the stock specialized nodes, all of their configs will have a `nodeConfig` member which is the config to use with the base node. This is where the initial state can be configured for specialized nodes: ```c dataSourceNodeConfig.nodeConfig.initialState = ma_node_state_stopped; ``` When using a specialized node like `ma_data_source_node` or `ma_splitter_node`, be sure to not modify the `vtable` member of the `nodeConfig` object. 7.1. Timing ----------- The node graph supports starting and stopping nodes at scheduled times. This is especially useful for data source nodes where you want to get the node set up, but only start playback at a specific time. There are two clocks: local and global. A local clock is per-node, whereas the global clock is per graph. Scheduling starts and stops can only be done based on the global clock because the local clock will not be running while the node is stopped. The global clocks advances whenever `ma_node_graph_read_pcm_frames()` is called. On the other hand, the local clock only advances when the node's processing callback is fired, and is advanced based on the output frame count. To retrieve the global time, use `ma_node_graph_get_time()`. The global time can be set with `ma_node_graph_set_time()` which might be useful if you want to do seeking on a global timeline. Getting and setting the local time is similar. Use `ma_node_get_time()` to retrieve the local time, and `ma_node_set_time()` to set the local time. The global and local times will be advanced by the audio thread, so care should be taken to avoid data races. Ideally you should avoid calling these outside of the node processing callbacks which are always run on the audio thread. There is basic support for scheduling the starting and stopping of nodes. You can only schedule one start and one stop at a time. This is mainly intended for putting nodes into a started or stopped state in a frame-exact manner. Without this mechanism, starting and stopping of a node is limited to the resolution of a call to `ma_node_graph_read_pcm_frames()` which would typically be in blocks of several milliseconds. The following APIs can be used for scheduling node states: ```c ma_node_set_state_time() ma_node_get_state_time() ``` The time is absolute and must be based on the global clock. An example is below: ```c ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1); // Delay starting to 1 second. ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5); // Delay stopping to 5 seconds. ``` An example for changing the state using a relative time. ```c ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1 + ma_node_graph_get_time(&myNodeGraph)); ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5 + ma_node_graph_get_time(&myNodeGraph)); ``` Note that due to the nature of multi-threading the times may not be 100% exact. If this is an issue, consider scheduling state changes from within a processing callback. An idea might be to have some kind of passthrough trigger node that is used specifically for tracking time and handling events. 7.2. Thread Safety and Locking ------------------------------ When processing audio, it's ideal not to have any kind of locking in the audio thread. Since it's expected that `ma_node_graph_read_pcm_frames()` would be run on the audio thread, it does so without the use of any locks. This section discusses the implementation used by miniaudio and goes over some of the compromises employed by miniaudio to achieve this goal. Note that the current implementation may not be ideal - feedback and critiques are most welcome. The node graph API is not *entirely* lock-free. Only `ma_node_graph_read_pcm_frames()` is expected to be lock-free. Attachment, detachment and uninitialization of nodes use locks to simplify the implementation, but are crafted in a way such that such locking is not required when reading audio data from the graph. Locking in these areas are achieved by means of spinlocks. The main complication with keeping `ma_node_graph_read_pcm_frames()` lock-free stems from the fact that a node can be uninitialized, and it's memory potentially freed, while in the middle of being processed on the audio thread. There are times when the audio thread will be referencing a node, which means the uninitialization process of a node needs to make sure it delays returning until the audio thread is finished so that control is not handed back to the caller thereby giving them a chance to free the node's memory. When the audio thread is processing a node, it does so by reading from each of the output buses of the node. In order for a node to process data for one of it's output buses, it needs to read from each of it's input buses, and so on an so forth. It follows that once all output buses of a node are detached, the node as a whole will be disconnected and no further processing will occur unless it's output buses are reattached, which won't be happening when the node is being uninitialized. By having `ma_node_detach_output_bus()` wait until the audio thread is finished with it, we can simplify a few things, at the expense of making `ma_node_detach_output_bus()` a bit slower. By doing this, the implementation of `ma_node_uninit()` becomes trivial - just detach all output nodes, followed by each of the attachments to each of it's input nodes, and then do any final clean up. With the above design, the worst-case scenario is `ma_node_detach_output_bus()` taking as long as it takes to process the output bus being detached. This will happen if it's called at just the wrong moment where the audio thread has just iterated it and has just started processing. The caller of `ma_node_detach_output_bus()` will stall until the audio thread is finished, which includes the cost of recursively processing it's inputs. This is the biggest compromise made with the approach taken by miniaudio for it's lock-free processing system. The cost of detaching nodes earlier in the pipeline (data sources, for example) will be cheaper than the cost of detaching higher level nodes, such as some kind of final post-processing endpoint. If you need to do mass detachments, detach starting from the lowest level nodes and work your way towards the final endpoint node (but don't try detaching the node graph's endpoint). If the audio thread is not running, detachment will be fast and detachment in any order will be the same. The reason nodes need to wait for their input attachments to complete is due to the potential for desyncs between data sources. If the node was to terminate processing mid way through processing it's inputs, there's a chance that some of the underlying data sources will have been read, but then others not. That will then result in a potential desynchronization when detaching and reattaching higher-level nodes. A possible solution to this is to have an option when detaching to terminate processing before processing all input attachments which should be fairly simple. Another compromise, albeit less significant, is locking when attaching and detaching nodes. This locking is achieved by means of a spinlock in order to reduce memory overhead. A lock is present for each input bus and output bus. When an output bus is connected to an input bus, both the output bus and input bus is locked. This locking is specifically for attaching and detaching across different threads and does not affect `ma_node_graph_read_pcm_frames()` in any way. The locking and unlocking is mostly self-explanatory, but a slightly less intuitive aspect comes into it when considering that iterating over attachments must not break as a result of attaching or detaching a node while iteration is occurring. Attaching and detaching are both quite simple. When an output bus of a node is attached to an input bus of another node, it's added to a linked list. Basically, an input bus is a linked list, where each item in the list is and output bus. We have some intentional (and convenient) restrictions on what can done with the linked list in order to simplify the implementation. First of all, whenever something needs to iterate over the list, it must do so in a forward direction. Backwards iteration is not supported. Also, items can only be added to the start of the list. The linked list is a doubly-linked list where each item in the list (an output bus) holds a pointer to the next item in the list, and another to the previous item. A pointer to the previous item is only required for fast detachment of the node - it is never used in iteration. This is an important property because it means from the perspective of iteration, attaching and detaching of an item can be done with a single atomic assignment. This is exploited by both the attachment and detachment process. When attaching the node, the first thing that is done is the setting of the local "next" and "previous" pointers of the node. After that, the item is "attached" to the list by simply performing an atomic exchange with the head pointer. After that, the node is "attached" to the list from the perspective of iteration. Even though the "previous" pointer of the next item hasn't yet been set, from the perspective of iteration it's been attached because iteration will only be happening in a forward direction which means the "previous" pointer won't actually ever get used. The same general process applies to detachment. See `ma_node_attach_output_bus()` and `ma_node_detach_output_bus()` for the implementation of this mechanism. 8. Decoding =========== The `ma_decoder` API is used for reading audio files. Decoders are completely decoupled from devices and can be used independently. Built-in support is included for the following formats: +---------+ | Format | +---------+ | WAV | | MP3 | | FLAC | +---------+ You can disable the built-in decoders by specifying one or more of the following options before the miniaudio implementation: ```c #define MA_NO_WAV #define MA_NO_MP3 #define MA_NO_FLAC ``` miniaudio supports the ability to plug in custom decoders. See the section below for details on how to use custom decoders. A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with `ma_decoder_init_memory()`, or from data delivered via callbacks with `ma_decoder_init()`. Here is an example for loading a decoder from a file: ```c ma_decoder decoder; ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder); if (result != MA_SUCCESS) { return false; // An error occurred. } ... ma_decoder_uninit(&decoder); ``` When initializing a decoder, you can optionally pass in a pointer to a `ma_decoder_config` object (the `NULL` argument in the example above) which allows you to configure the output format, channel count, sample rate and channel map: ```c ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000); ``` When passing in `NULL` for decoder config in `ma_decoder_init*()`, the output format will be the same as that defined by the decoding backend. Data is read from the decoder as PCM frames. This will output the number of PCM frames actually read. If this is less than the requested number of PCM frames it means you've reached the end. The return value will be `MA_AT_END` if no samples have been read and the end has been reached. ```c ma_result result = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead, &framesRead); if (framesRead < framesToRead) { // Reached the end. } ``` You can also seek to a specific frame like so: ```c ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame); if (result != MA_SUCCESS) { return false; // An error occurred. } ``` If you want to loop back to the start, you can simply seek back to the first PCM frame: ```c ma_decoder_seek_to_pcm_frame(pDecoder, 0); ``` When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding backend. This can be unnecessarily inefficient if the type is already known. In this case you can use `encodingFormat` variable in the device config to specify a specific encoding format you want to decode: ```c decoderConfig.encodingFormat = ma_encoding_format_wav; ``` See the `ma_encoding_format` enum for possible encoding formats. The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer. 8.1. Custom Decoders -------------------- It's possible to implement a custom decoder and plug it into miniaudio. This is extremely useful when you want to use the `ma_decoder` API, but need to support an encoding format that's not one of the stock formats supported by miniaudio. This can be put to particularly good use when using the `ma_engine` and/or `ma_resource_manager` APIs because they use `ma_decoder` internally. If, for example, you wanted to support Opus, you can do so with a custom decoder (there if a reference Opus decoder in the "extras" folder of the miniaudio repository which uses libopus + libopusfile). A custom decoder must implement a data source. A vtable called `ma_decoding_backend_vtable` needs to be implemented which is then passed into the decoder config: ```c ma_decoding_backend_vtable* pCustomBackendVTables[] = { &g_ma_decoding_backend_vtable_libvorbis, &g_ma_decoding_backend_vtable_libopus }; ... decoderConfig = ma_decoder_config_init_default(); decoderConfig.pCustomBackendUserData = NULL; decoderConfig.ppCustomBackendVTables = pCustomBackendVTables; decoderConfig.customBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); ``` The `ma_decoding_backend_vtable` vtable has the following functions: ``` onInit onInitFile onInitFileW onInitMemory onUninit ``` There are only two functions that must be implemented - `onInit` and `onUninit`. The other functions can be implemented for a small optimization for loading from a file path or memory. If these are not specified, miniaudio will deal with it for you via a generic implementation. When you initialize a custom data source (by implementing the `onInit` function in the vtable) you will need to output a pointer to a `ma_data_source` which implements your custom decoder. See the section about data sources for details on how to implement this. Alternatively, see the "custom_decoders" example in the miniaudio repository. The `onInit` function takes a pointer to some callbacks for the purpose of reading raw audio data from some arbitrary source. You'll use these functions to read from the raw data and perform the decoding. When you call them, you will pass in the `pReadSeekTellUserData` pointer to the relevant parameter. The `pConfig` parameter in `onInit` can be used to configure the backend if appropriate. It's only used as a hint and can be ignored. However, if any of the properties are relevant to your decoder, an optimal implementation will handle the relevant properties appropriately. If memory allocation is required, it should be done so via the specified allocation callbacks if possible (the `pAllocationCallbacks` parameter). If an error occurs when initializing the decoder, you should leave `ppBackend` unset, or set to NULL, and make sure everything is cleaned up appropriately and an appropriate result code returned. When multiple custom backends are specified, miniaudio will cycle through the vtables in the order they're listed in the array that's passed into the decoder config so it's important that your initialization routine is clean. When a decoder is uninitialized, the `onUninit` callback will be fired which will give you an opportunity to clean up and internal data. 9. Encoding =========== The `ma_encoding` API is used for writing audio files. The only supported output format is WAV. This can be disabled by specifying the following option before the implementation of miniaudio: ```c #define MA_NO_WAV ``` An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data delivered via callbacks with `ma_encoder_init()`. Below is an example for initializing an encoder to output to a file. ```c ma_encoder_config config = ma_encoder_config_init(ma_encoding_format_wav, FORMAT, CHANNELS, SAMPLE_RATE); ma_encoder encoder; ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder); if (result != MA_SUCCESS) { // Error } ... ma_encoder_uninit(&encoder); ``` When initializing an encoder you must specify a config which is initialized with `ma_encoder_config_init()`. Here you must specify the file type, the output sample format, output channel count and output sample rate. The following file types are supported: +------------------------+-------------+ | Enum | Description | +------------------------+-------------+ | ma_encoding_format_wav | WAV | +------------------------+-------------+ If the format, channel count or sample rate is not supported by the output file type an error will be returned. The encoder will not perform data conversion so you will need to convert it before outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the example below: ```c framesWritten = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite); ``` Encoders must be uninitialized with `ma_encoder_uninit()`. 10. Data Conversion =================== A data conversion API is included with miniaudio which supports the majority of data conversion requirements. This supports conversion between sample formats, channel counts (with channel mapping) and sample rates. 10.1. Sample Format Conversion ------------------------------ Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and `ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()` to convert between two specific formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use `ma_convert_pcm_frames_format()` to convert PCM frames where you want to specify the frame count and channel count as a variable instead of the total sample count. 10.1.1. Dithering ----------------- Dithering can be set using the ditherMode parameter. The different dithering modes include the following, in order of efficiency: +-----------+--------------------------+ | Type | Enum Token | +-----------+--------------------------+ | None | ma_dither_mode_none | | Rectangle | ma_dither_mode_rectangle | | Triangle | ma_dither_mode_triangle | +-----------+--------------------------+ Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be ignored for conversions where dithering is not needed. Dithering is available for the following conversions: ``` s16 -> u8 s24 -> u8 s32 -> u8 f32 -> u8 s24 -> s16 s32 -> s16 f32 -> s16 ``` Note that it is not an error to pass something other than ma_dither_mode_none for conversions where dither is not used. It will just be ignored. 10.2. Channel Conversion ------------------------ Channel conversion is used for channel rearrangement and conversion from one channel count to another. The `ma_channel_converter` API is used for channel conversion. Below is an example of initializing a simple channel converter which converts from mono to stereo. ```c ma_channel_converter_config config = ma_channel_converter_config_init( ma_format, // Sample format 1, // Input channels NULL, // Input channel map 2, // Output channels NULL, // Output channel map ma_channel_mix_mode_default); // The mixing algorithm to use when combining channels. result = ma_channel_converter_init(&config, NULL, &converter); if (result != MA_SUCCESS) { // Error. } ``` To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so: ```c ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount); if (result != MA_SUCCESS) { // Error. } ``` It is up to the caller to ensure the output buffer is large enough to accommodate the new PCM frames. Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported. 10.2.1. Channel Mapping ----------------------- In addition to converting from one channel count to another, like the example above, the channel converter can also be used to rearrange channels. When initializing the channel converter, you can optionally pass in channel maps for both the input and output frames. If the channel counts are the same, and each channel map contains the same channel positions with the exception that they're in a different order, a simple shuffling of the channels will be performed. If, however, there is not a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed based on a mixing mode which is specified when initializing the `ma_channel_converter_config` object. When converting from mono to multi-channel, the mono channel is simply copied to each output channel. When going the other way around, the audio of each output channel is simply averaged and copied to the mono channel. In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess channels and silence extra channels. For example, converting from 4 to 2 channels, the 3rd and 4th channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and 4th channels. The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a simple distribution between input and output. Imagine sitting in the middle of a room, with speakers on the walls representing channel positions. The `MA_CHANNEL_FRONT_LEFT` position can be thought of as being in the corner of the front and left walls. Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined weights. Custom weights can be passed in as the last parameter of `ma_channel_converter_config_init()`. Predefined channel maps can be retrieved with `ma_channel_map_init_standard()`. This takes a `ma_standard_channel_map` enum as it's first parameter, which can be one of the following: +-----------------------------------+-----------------------------------------------------------+ | Name | Description | +-----------------------------------+-----------------------------------------------------------+ | ma_standard_channel_map_default | Default channel map used by miniaudio. See below. | | ma_standard_channel_map_microsoft | Channel map used by Microsoft's bitfield channel maps. | | ma_standard_channel_map_alsa | Default ALSA channel map. | | ma_standard_channel_map_rfc3551 | RFC 3551.

| | | 1: MA_CHANNEL_FRONT_RIGHT | +---------------+---------------------------------+ | 3 | 0: MA_CHANNEL_FRONT_LEFT
| | | 1: MA_CHANNEL_FRONT_RIGHT
| | | 2: MA_CHANNEL_FRONT_CENTER | +---------------+---------------------------------+ | 4 (Surround) | 0: MA_CHANNEL_FRONT_LEFT

| | | 3: MA_CHANNEL_BACK_CENTER | +---------------+---------------------------------+ | 5 | 0: MA_CHANNEL_FRONT_LEFT
| | | 1: MA_CHANNEL_FRONT_RIGHT

| | | 7: MA_CHANNEL_SIDE_RIGHT | +---------------+---------------------------------+ | Other | All channels set to 0. This | | | is equivalent to the same | | | mapping as the device. | +---------------+---------------------------------+ 10.3. Resampling ---------------- Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something like the following: ```c ma_resampler_config config = ma_resampler_config_init( ma_format_s16, channels, sampleRateIn, sampleRateOut, ma_resample_algorithm_linear); ma_resampler resampler; ma_result result = ma_resampler_init(&config, &resampler); if (result != MA_SUCCESS) { // An error occurred... } ``` Do the following to uninitialize the resampler: ```c ma_resampler_uninit(&resampler); ``` The following example shows how data can be processed ```c ma_uint64 frameCountIn = 1000; ma_uint64 frameCountOut = 2000; ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); if (result != MA_SUCCESS) { // An error occurred... } // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the // number of output frames written. ``` To initialize the resampler you first need to set up a config (`ma_resampler_config`) with `ma_resampler_config_init()`. You need to specify the sample format you want to use, the number of channels, the input and output sample rate, and the algorithm. The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format you will need to perform pre- and post-conversions yourself where necessary. Note that the format is the same for both input and output. The format cannot be changed after initialization. The resampler supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization. The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the only configuration property that can be changed after initialization. The miniaudio resampler has built-in support for the following algorithms: +-----------+------------------------------+ | Algorithm | Enum Token | +-----------+------------------------------+ | Linear | ma_resample_algorithm_linear | | Custom | ma_resample_algorithm_custom | +-----------+------------------------------+ The algorithm cannot be changed after initialization. Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process frames, use `ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek. The sample rate can be changed dynamically on the fly. You can change this with explicit sample rates with `ma_resampler_set_rate()` and also with a decimal ratio with `ma_resampler_set_rate_ratio()`. The ratio is in/out. Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with `ma_resampler_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`. Due to the nature of how resampling works, the resampler introduces some latency. This can be retrieved in terms of both the input rate and the output rate with `ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`. 10.3.1. Resampling Algorithms ----------------------------- The choice of resampling algorithm depends on your situation and requirements. 10.3.1.1. Linear Resampling --------------------------- The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, some control over the quality of the linear resampler which may make it a suitable option depending on your requirements. The linear resampler performs low-pass filtering before or after downsampling or upsampling, depending on the sample rates you're converting between. When decreasing the sample rate, the low-pass filter will be applied before downsampling. When increasing the rate it will be performed after upsampling. By default a fourth order low-pass filter will be applied. This can be configured via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering. The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of the input and output sample rates (Nyquist Frequency). The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`. 10.3.2. Custom Resamplers ------------------------- You can implement a custom resampler by using the `ma_resample_algorithm_custom` resampling algorithm and setting a vtable in the resampler config: ```c ma_resampler_config config = ma_resampler_config_init(..., ma_resample_algorithm_custom); config.pBackendVTable = &g_customResamplerVTable; ``` Custom resamplers are useful if the stock algorithms are not appropriate for your use case. You need to implement the required functions in `ma_resampling_backend_vtable`. Note that not all functions in the vtable need to be implemented, but if it's possible to implement, they should be. You can use the `ma_linear_resampler` object for an example on how to implement the vtable. The `onGetHeapSize` callback is used to calculate the size of any internal heap allocation the custom resampler will need to make given the supplied config. When you initialize the resampler via the `onInit` callback, you'll be given a pointer to a heap allocation which is where you should store the heap allocated data. You should not free this data in `onUninit` because miniaudio will manage it for you. The `onProcess` callback is where the actual resampling takes place. On input, `pFrameCountIn` points to a variable containing the number of frames in the `pFramesIn` buffer and `pFrameCountOut` points to a variable containing the capacity in frames of the `pFramesOut` buffer. On output, `pFrameCountIn` should be set to the number of input frames that were fully consumed, whereas `pFrameCountOut` should be set to the number of frames that were written to `pFramesOut`. The `onSetRate` callback is optional and is used for dynamically changing the sample rate. If dynamic rate changes are not supported, you can set this callback to NULL. The `onGetInputLatency` and `onGetOutputLatency` functions are used for retrieving the latency in input and output rates respectively. These can be NULL in which case latency calculations will be assumed to be NULL. The `onGetRequiredInputFrameCount` callback is used to give miniaudio a hint as to how many input frames are required to be available to produce the given number of output frames. Likewise, the `onGetExpectedOutputFrameCount` callback is used to determine how many output frames will be produced given the specified number of input frames. miniaudio will use these as a hint, but they are optional and can be set to NULL if you're unable to implement them. 10.4. General Data Conversion ----------------------------- The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and resampling into one operation. This is what miniaudio uses internally to convert between the format requested when the device was initialized and the format of the backend's native device. The API for general data conversion is very similar to the resampling API. Create a `ma_data_converter` object like this: ```c ma_data_converter_config config = ma_data_converter_config_init( inputFormat, outputFormat, inputChannels, outputChannels, inputSampleRate, outputSampleRate ); ma_data_converter converter; ma_result result = ma_data_converter_init(&config, NULL, &converter); if (result != MA_SUCCESS) { // An error occurred... } ``` In the example above we use `ma_data_converter_config_init()` to initialize the config, however there's many more properties that can be configured, such as channel maps and resampling quality. Something like the following may be more suitable depending on your requirements: ```c ma_data_converter_config config = ma_data_converter_config_init_default(); config.formatIn = inputFormat; config.formatOut = outputFormat; config.channelsIn = inputChannels; config.channelsOut = outputChannels; config.sampleRateIn = inputSampleRate; config.sampleRateOut = outputSampleRate; ma_channel_map_init_standard(ma_standard_channel_map_flac, config.channelMapIn, sizeof(config.channelMapIn)/sizeof(config.channelMapIn[0]), config.channelCountIn); config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER; ``` Do the following to uninitialize the data converter: ```c ma_data_converter_uninit(&converter, NULL); ``` The following example shows how data can be processed ```c ma_uint64 frameCountIn = 1000; ma_uint64 frameCountOut = 2000; ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); if (result != MA_SUCCESS) { // An error occurred... } // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number // of output frames written. ``` The data converter supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization. Sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the only configuration property that can be changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of `ma_data_converter_config` is set to `MA_TRUE`. To change the sample rate, use `ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. The resampling algorithm cannot be changed after initialization. Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process frames, use `ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek. Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with `ma_data_converter_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`. Due to the nature of how resampling works, the data converter introduces some latency if resampling is required. This can be retrieved in terms of both the input rate and the output rate with `ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`. 11. Filtering ============= 11.1. Biquad Filtering ---------------------- Biquad filtering is achieved with the `ma_biquad` API. Example: ```c ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2); ma_result result = ma_biquad_init(&config, &biquad); if (result != MA_SUCCESS) { // Error. } ... ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount); ``` Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, b1 and b2, and the denominator coefficients are a0, a1 and a2. The a0 coefficient is required and coefficients must not be pre-normalized. Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. When using `ma_format_s16` the biquad filter will use fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used. Input and output frames are always interleaved. Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so: ```c ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount); ``` If you need to change the values of the coefficients, but maintain the values in the registers you can do so with `ma_biquad_reinit()`. This is useful if you need to change the properties of the filter while keeping the values of registers valid to avoid glitching. Do not use `ma_biquad_init()` for this as it will do a full initialization which involves clearing the registers to 0. Note that changing the format or channel count after initialization is invalid and will result in an error. 11.2. Low-Pass Filtering ------------------------ Low-pass filtering is achieved with the following APIs: +---------+------------------------------------------+ | API | Description | +---------+------------------------------------------+ | ma_lpf1 | First order low-pass filter | | ma_lpf2 | Second order low-pass filter | | ma_lpf | High order low-pass filter (Butterworth) | +---------+------------------------------------------+ Low-pass filter example: ```c ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order); ma_result result = ma_lpf_init(&config, &lpf); if (result != MA_SUCCESS) { // Error. } ... ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount); ``` Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. Input and output frames are always interleaved. Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so: ```c ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount); ``` The maximum filter order is limited to `MA_MAX_FILTER_ORDER` which is set to 8. If you need more, you can chain first and second order filters together. ```c for (iFilter = 0; iFilter < filterCount; iFilter += 1) { ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount); } ``` If you need to change the configuration of the filter, but need to maintain the state of internal registers you can do so with `ma_lpf_reinit()`. This may be useful if you need to change the sample rate and/or cutoff frequency dynamically while maintaining smooth transitions. Note that changing the format or channel count after initialization is invalid and will result in an error. The `ma_lpf` object supports a configurable order, but if you only need a first order filter you may want to consider using `ma_lpf1`. Likewise, if you only need a second order filter you can use `ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient. If an even filter order is specified, a series of second order filters will be processed in a chain. If an odd filter order is specified, a first order filter will be applied, followed by a series of second order filters in a chain. 11.3. High-Pass Filtering ------------------------- High-pass filtering is achieved with the following APIs: +---------+-------------------------------------------+ | API | Description | +---------+-------------------------------------------+ | ma_hpf1 | First order high-pass filter | | ma_hpf2 | Second order high-pass filter | | ma_hpf | High order high-pass filter (Butterworth) | +---------+-------------------------------------------+ High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, `ma_hpf2` and `ma_hpf`. See example code for low-pass filters for example usage. 11.4. Band-Pass Filtering ------------------------- Band-pass filtering is achieved with the following APIs: +---------+-------------------------------+ | API | Description | +---------+-------------------------------+ | ma_bpf2 | Second order band-pass filter | | ma_bpf | High order band-pass filter | +---------+-------------------------------+ Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and `ma_hpf`. See example code for low-pass filters for example usage. Note that the order for band-pass filters must be an even number which means there is no first order band-pass filter, unlike low-pass and high-pass filters. 11.5. Notch Filtering --------------------- Notch filtering is achieved with the following APIs: +-----------+------------------------------------------+ | API | Description | +-----------+------------------------------------------+ | ma_notch2 | Second order notching filter | +-----------+------------------------------------------+ 11.6. Peaking EQ Filtering ------------------------- Peaking filtering is achieved with the following APIs: +----------+------------------------------------------+ | API | Description | +----------+------------------------------------------+ | ma_peak2 | Second order peaking filter | +----------+------------------------------------------+ 11.7. Low Shelf Filtering ------------------------- Low shelf filtering is achieved with the following APIs: +-------------+------------------------------------------+ | API | Description | +-------------+------------------------------------------+ | ma_loshelf2 | Second order low shelf filter | +-------------+------------------------------------------+ Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to just turn them down rather than eliminate them entirely. 11.8. High Shelf Filtering -------------------------- High shelf filtering is achieved with the following APIs: +-------------+------------------------------------------+ | API | Description | +-------------+------------------------------------------+ | ma_hishelf2 | Second order high shelf filter | +-------------+------------------------------------------+ The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` instead of `ma_loshelf`. Where a low shelf filter is used to adjust the volume of low frequencies, the high shelf filter does the same thing for high frequencies. 12. Waveform and Noise Generation ================================= 12.1. Waveforms --------------- miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example: ```c ma_waveform_config config = ma_waveform_config_init( FORMAT, CHANNELS, SAMPLE_RATE, ma_waveform_type_sine, amplitude, frequency); ma_waveform waveform; ma_result result = ma_waveform_init(&config, &waveform); if (result != MA_SUCCESS) { // Error. } ... ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount); ``` The amplitude, frequency, type, and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()`, `ma_waveform_set_type()`, and `ma_waveform_set_sample_rate()` respectively. You can invert the waveform by setting the amplitude to a negative value. You can use this to control whether or not a sawtooth has a positive or negative ramp, for example. Below are the supported waveform types: +---------------------------+ | Enum Name | +---------------------------+ | ma_waveform_type_sine | | ma_waveform_type_square | | ma_waveform_type_triangle | | ma_waveform_type_sawtooth | +---------------------------+ 12.2. Noise ----------- miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example: ```c ma_noise_config config = ma_noise_config_init( FORMAT, CHANNELS, ma_noise_type_white, SEED, amplitude); ma_noise noise; ma_result result = ma_noise_init(&config, &noise); if (result != MA_SUCCESS) { // Error. } ... ma_noise_read_pcm_frames(&noise, pOutput, frameCount); ``` The noise API uses simple LCG random number generation. It supports a custom seed which is useful for things like automated testing requiring reproducibility. Setting the seed to zero will default to `MA_DEFAULT_LCG_SEED`. The amplitude and seed can be changed dynamically with `ma_noise_set_amplitude()` and `ma_noise_set_seed()` respectively. By default, the noise API will use different values for different channels. So, for example, the left side in a stereo stream will be different to the right side. To instead have each channel use the same random value, set the `duplicateChannels` member of the noise config to true, like so: ```c config.duplicateChannels = MA_TRUE; ``` Below are the supported noise types. +------------------------+ | Enum Name | +------------------------+ | ma_noise_type_white | | ma_noise_type_pink | | ma_noise_type_brownian | +------------------------+ 13. Audio Buffers ================= miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can read from memory that's managed by the application, but can also handle the memory management for you internally. Memory management is flexible and should support most use cases. Audio buffers are initialised using the standard configuration system used everywhere in miniaudio: ```c ma_audio_buffer_config config = ma_audio_buffer_config_init( format, channels, sizeInFrames, pExistingData, &allocationCallbacks); ma_audio_buffer buffer; result = ma_audio_buffer_init(&config, &buffer); if (result != MA_SUCCESS) { // Error. } ... ma_audio_buffer_uninit(&buffer); ``` In the example above, the memory pointed to by `pExistingData` will *not* be copied and is how an application can do self-managed memory allocation. If you would rather make a copy of the data, use `ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`. Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure and the raw audio data in a contiguous block of memory. That is, the raw audio data will be located immediately after the `ma_audio_buffer` structure. To do this, use `ma_audio_buffer_alloc_and_init()`: ```c ma_audio_buffer_config config = ma_audio_buffer_config_init( format, channels, sizeInFrames, pExistingData, &allocationCallbacks); ma_audio_buffer* pBuffer result = ma_audio_buffer_alloc_and_init(&config, &pBuffer); if (result != MA_SUCCESS) { // Error } ... ma_audio_buffer_uninit_and_free(&buffer); ``` If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it with `ma_audio_buffer_uninit_and_free()`. In the example above, the memory pointed to by `pExistingData` will be copied into the buffer, which is contrary to the behavior of `ma_audio_buffer_init()`. An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the cursor moves forward. The last parameter (`loop`) can be used to determine if the buffer should loop. The return value is the number of frames actually read. If this is less than the number of frames requested it means the end has been reached. This should never happen if the `loop` parameter is set to true. If you want to manually loop back to the start, you can do so with with `ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an audio buffer. ```c ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping); if (framesRead < desiredFrameCount) { // If not looping, this means the end has been reached. This should never happen in looping mode with valid input. } ``` Sometimes you may want to avoid the cost of data movement between the internal buffer and the output buffer. Instead you can use memory mapping to retrieve a pointer to a segment of data: ```c void* pMappedFrames; ma_uint64 frameCount = frameCountToTryMapping; ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount); if (result == MA_SUCCESS) { // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be // less due to the end of the buffer being reached. ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels); // You must unmap the buffer. ma_audio_buffer_unmap(pAudioBuffer, frameCount); } ``` When you use memory mapping, the read cursor is increment by the frame count passed in to `ma_audio_buffer_unmap()`. If you decide not to process every frame you can pass in a value smaller than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is that it does not handle looping for you. You can determine if the buffer is at the end for the purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of `ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` as an error when returned by `ma_audio_buffer_unmap()`. 14. Ring Buffers ================ miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates on bytes, whereas the `ma_pcm_rb` operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around `ma_rb`. Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved streams. The caller can also allocate their own backing memory for the ring buffer to use internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for you. The examples below use the PCM frame variant of the ring buffer since that's most likely the one you will want to use. To initialize a ring buffer, do something like the following: ```c ma_pcm_rb rb; ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb); if (result != MA_SUCCESS) { // Error } ``` The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because it's the PCM variant of the ring buffer API. For the regular ring buffer that operates on bytes you would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes instead of frames. The fourth parameter is an optional pre-allocated buffer and the fifth parameter is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation routines. Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used. Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is offset from each other based on the stride. To manage your sub-buffers you can use `ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and `ma_pcm_rb_get_subbuffer_ptr()`. Use `ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section of the ring buffer. You specify the number of frames you need, and on output it will set to what was actually acquired. If the read or write pointer is positioned such that the number of frames requested will require a loop, it will be clamped to the end of the buffer. Therefore, the number of frames you're given may be less than the number you requested. After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the buffer and then "commit" it with `ma_pcm_rb_commit_read()` or `ma_pcm_rb_commit_write()`. This is where the read/write pointers are updated. When you commit you need to pass in the buffer that was returned by the earlier call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and `ma_pcm_rb_commit_write()` is what's used to increment the pointers, and can be less that what was originally requested. If you want to correct for drift between the write pointer and the read pointer you can use a combination of `ma_pcm_rb_pointer_distance()`, `ma_pcm_rb_seek_read()` and `ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only move the read pointer forward via the consumer thread, and the write pointer forward by the producer thread. If there is too much space between the pointers, move the read pointer forward. If there is too little space between the pointers, move the write pointer forward. You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` API. This is exactly the same, only you will use the `ma_rb` functions instead of `ma_pcm_rb` and instead of frame counts you will pass around byte counts. The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most significant bit being used to encode a loop flag and the internally managed buffers always being aligned to `MA_SIMD_ALIGNMENT`. Note that the ring buffer is only thread safe when used by a single consumer thread and single producer thread. 15. Backends ============ The following backends are supported by miniaudio. These are listed in order of default priority. When no backend is specified when initializing a context or device, miniaudio will attempt to use each of these backends in the order listed in the table below. Note that backends that are not usable by the build target will not be included in the build. For example, ALSA, which is specific to Linux, will not be included in the Windows build. +-------------+-----------------------+--------------------------------------------------------+ | Name | Enum Name | Supported Operating Systems | +-------------+-----------------------+--------------------------------------------------------+ | WASAPI | ma_backend_wasapi | Windows Vista+ | | DirectSound | ma_backend_dsound | Windows XP+ | | WinMM | ma_backend_winmm | Windows 95+ | | Core Audio | ma_backend_coreaudio | macOS, iOS | | sndio | ma_backend_sndio | OpenBSD | | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD | | OSS | ma_backend_oss | FreeBSD | | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) | | ALSA | ma_backend_alsa | Linux | | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) | | AAudio | ma_backend_aaudio | Android 8+ | | OpenSL ES | ma_backend_opensl | Android (API level 16+) | | Web Audio | ma_backend_webaudio | Web (via Emscripten) | | Custom | ma_backend_custom | Cross Platform | | Null | ma_backend_null | Cross Platform (not used on Web) | +-------------+-----------------------+--------------------------------------------------------+ Some backends have some nuance details you may want to be aware of. 15.1. WASAPI ------------ - Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the device's native sample rate. To work around this, set `wasapi.noAutoConvertSRC` to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing when the `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's internal resampler being used instead which will in turn enable the use of low-latency shared mode. 15.2. PulseAudio ---------------- - If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki: https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. Alternatively, consider using a different backend such as ALSA. 15.3. Android ------------- - To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: `` - With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES. - With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are enumerated through Java). You can however perform your own device enumeration through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init(). - The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in resampler is to take advantage of any potential device-specific optimizations the driver may implement. BSD --- - The sndio backend is currently only enabled on OpenBSD builds. - The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can use it. 15.4. UWP --------- - UWP only supports default playback and capture devices. - UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): ``` ... ``` 15.5. Web Audio / Emscripten ---------------------------- - You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build. - The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act as a factory for device objects. - Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated. - Google has implemented a policy in their browsers that prevent automatic media output without first receiving some kind of user input. The following web page has additional details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device may fail if you try to start playback without first handling some kind of user input. 16. Optimization Tips ===================== See below for some tips on improving performance. 16.1. Low Level API ------------------- - In the data callback, if your data is already clipped prior to copying it into the output buffer, set the `noClip` config option in the device config to true. This will disable miniaudio's built in clipping function. - By default, miniaudio will pre-silence the data callback's output buffer. If you know that you will always write valid data to the output buffer you can disable pre-silencing by setting the `noPreSilence` config option in the device config to true. 16.2. High Level API -------------------- - If a sound does not require doppler or pitch shifting, consider disabling pitching by initializing the sound with the `MA_SOUND_FLAG_NO_PITCH` flag. - If a sound does not require spatialization, disable it by initializing the sound with the `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. It can be re-enabled again post-initialization with `ma_sound_set_spatialization_enabled()`. - If you know all of your sounds will always be the same sample rate, set the engine's sample rate to match that of the sounds. Likewise, if you're using a self-managed resource manager, consider setting the decoded sample rate to match your sounds. By configuring everything to use a consistent sample rate, sample rate conversion can be avoided. 17. Miscellaneous Notes ======================= - Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI and Core Audio, however other backends such as PulseAudio may naturally support it, though not all have been tested. - When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This is due to 64-bit file APIs not being available. */ #ifndef miniaudio_h #define miniaudio_h #ifdef __cplusplus extern "C" { #endif #define MA_STRINGIFY(x) #x #define MA_XSTRINGIFY(x) MA_STRINGIFY(x) #define MA_VERSION_MAJOR 0 #define MA_VERSION_MINOR 11 #define MA_VERSION_REVISION 18 #define MA_VERSION_STRING MA_XSTRINGIFY(MA_VERSION_MAJOR) "."

These are typesafe structures to prevent errors as a result of forgetting to reference variables atomically. It's too easy to introduce subtle bugs where you accidentally do a regular assignment instead of an atomic load/store, etc. By using a struct we can enforce the use of atomics at compile time. These types are declared in the header section because we need to reference them in structs below, but functions for using them are only exposed in the implementation section. I do not want these to be part of the public API. There's a few downsides to this system. The first is that you need to declare a new struct for each type. Below are some macros to help with the declarations. They will be named like so: ma_atomic_uint32 - atomic ma_uint32 ma_atomic_int32 - atomic ma_int32 ma_atomic_uint64 - atomic ma_uint64 ma_atomic_float - atomic float ma_atomic_bool32 - atomic ma_bool32 The other downside is that atomic pointers are extremely messy. You need to declare a new struct for each specific type of pointer you need to make atomic. For example, an atomic ma_node* will look like this: MA_ATOMIC_SAFE_TYPE_IMPL_PTR(node) Which will declare a type struct that's named like so: ma_atomic_ptr_node Functions to use the atomic types are declared in the implementation section. All atomic functions are prefixed with the name of the struct. For example: ma_atomic_uint32_set() - Atomic store of ma_uint32 ma_atomic_uint32_get() - Atomic load of ma_uint32 etc. For pointer types it's the same, which makes them a bit messy to use due to the length of each function name, but in return you get type safety and enforcement of atomic operations. */ #define MA_ATOMIC_SAFE_TYPE_DECL(c89TypeExtension, typeSize, type) \ typedef struct \ { \ MA_ATOMIC(typeSize, ma_##type) value; \ } ma_atomic_##type; \ #define MA_ATOMIC_SAFE_TYPE_DECL_PTR(type) \ typedef struct \ { \ MA_ATOMIC(MA_SIZEOF_PTR, ma_##type*) value; \ } ma_atomic_ptr_##type; \ MA_ATOMIC_SAFE_TYPE_DECL(32, 4, uint32) MA_ATOMIC_SAFE_TYPE_DECL(i32, 4, int32) MA_ATOMIC_SAFE_TYPE_DECL(64, 8, uint64) MA_ATOMIC_SAFE_TYPE_DECL(f32, 4, float) MA_ATOMIC_SAFE_TYPE_DECL(32, 4, bool32) /* Spinlocks are 32-bit for compatibility reasons. */ typedef ma_uint32 ma_spinlock; #ifndef MA_NO_THREADING /* Thread priorities should be ordered such that the default priority of the worker thread is 0. */ typedef enum { ma_thread_priority_idle = -5, ma_thread_priority_lowest = -4, ma_thread_priority_low = -3, ma_thread_priority_normal = -2, ma_thread_priority_high = -1, ma_thread_priority_highest = 0, ma_thread_priority_realtime = 1, ma_thread_priority_default = 0 } ma_thread_priority; #if defined(MA_POSIX) typedef ma_pthread_t ma_thread; #elif defined(MA_WIN32) typedef ma_handle ma_thread; #endif #if defined(MA_POSIX) typedef ma_pthread_mutex_t ma_mutex; #elif defined(MA_WIN32) typedef ma_handle ma_mutex; #endif #if defined(MA_POSIX) typedef struct { ma_uint32 value; ma_pthread_mutex_t lock; ma_pthread_cond_t cond; } ma_event; #elif defined(MA_WIN32) typedef ma_handle ma_event; #endif #if defined(MA_POSIX) typedef struct { int value; ma_pthread_mutex_t lock; ma_pthread_cond_t cond; } ma_semaphore; #elif defined(MA_WIN32) typedef ma_handle ma_semaphore; #endif #else /* MA_NO_THREADING is set which means threading is disabled.

This callback is used for notifying the application of changes such as when the device has started, stopped, rerouted or an interruption has occurred. Note that not all backends will post all notification types. For example, some backends will perform automatic stream routing without any kind of notification to the host program which means miniaudio will never know about it and will never be able to fire the rerouted notification. You should keep this in mind when designing your program. The stopped notification will *not* get fired when a device is rerouted. Parameters ---------- pNotification (in) A pointer to a structure containing information about the event. Use the `pDevice` member of this object to retrieve the relevant device. The `type` member can be used to discriminate against each of the notification types. Remarks ------- Do not restart or uninitialize the device from the callback. Not all notifications will be triggered by all backends, however the started and stopped events should be reliable for all backends. Some backends do not have a good way to detect device stoppages due to unplugging the device which may result in the stopped callback not getting fired. This has been observed with at least one BSD variant. The rerouted notification is fired *after* the reroute has occurred. The stopped notification will *not* get fired when a device is rerouted. The following backends are known to do automatic stream rerouting, but do not have a way to be notified of the change: * DirectSound The interruption notifications are used on mobile platforms for detecting when audio is interrupted due to things like an incoming phone call.

This is called as soon as the backend asks for more data which means it may be called with inconsistent frame counts. You cannot assume the callback will be fired with a consistent frame count. Parameters ---------- pDevice (in) A pointer to the relevant device. pOutput (out) A pointer to the output buffer that will receive audio data that will later be played back through the speakers. This will be non-null for a playback or full-duplex device and null for a capture and loopback device. pInput (in) A pointer to the buffer containing input data from a recording device. This will be non-null for a capture, full-duplex or loopback device and null for a playback device. frameCount (in) The number of PCM frames to process. Note that this will not necessarily be equal to what you requested when you initialized the device. The `periodSizeInFrames` and `periodSizeInMilliseconds` members of the device config are just hints, and are not necessarily exactly what you'll get. You must not assume this will always be the same value each time the callback is fired. Remarks ------- You cannot stop and start the device from inside the callback or else you'll get a deadlock. You must also not uninitialize the device from inside the callback. The following APIs cannot be called from inside the callback: ma_device_init() ma_device_init_ex() ma_device_uninit() ma_device_start() ma_device_stop() The proper way to stop the device is to call `ma_device_stop()` from a different thread, normally the main application thread. */ typedef void (* ma_device_data_proc)(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount); /* DEPRECATED.

These callbacks are grouped into two parts: context and device. There is one context to many devices. A device is created from a context. The general flow goes like this: 1) A context is created with `onContextInit()` 1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required. 1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required. 2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was selected from device enumeration via `onContextEnumerateDevices()`. 3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()` 4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by miniaudio internally. Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the callbacks defined in this structure. Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration needs to stop and the `onContextEnumerateDevices()` function returns with a success code. Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID, and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the case when the device ID is NULL, in which case information about the default device needs to be retrieved. Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created. This is a little bit more complicated than initialization of the context due to it's more complicated configuration. When initializing a device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input, the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to the requested format. The conversion between the format requested by the application and the device's native format will be handled internally by miniaudio. On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for sample rate. For the channel map, the default should be used when `ma_channel_map_is_blank()` returns true (all channels set to `MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_descriptor` object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set). Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented. The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and `onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within it's callback. This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback. If the backend requires absolute flexibility with it's data delivery, it can optionally implement the `onDeviceDataLoop()` callback which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional. The audio thread should run data delivery logic in a loop while `ma_device_get_state() == ma_device_state_started` and no errors have been encountered. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback. The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this callback. When the device is stopped, the `ma_device_get_state() == ma_device_state_started` condition will fail and the loop will be terminated which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback, look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to wake up the audio thread. If the backend supports an optimized retrieval of device information from an initialized `ma_device` object, it should implement the `onDeviceGetInfo()` callback. This is optional, in which case it will fall back to `onContextGetDeviceInfo()` which is less efficient. */ struct ma_backend_callbacks { ma_result (* onContextInit)(ma_context* pContext, const ma_context_config* pConfig, ma_backend_callbacks* pCallbacks); ma_result (* onContextUninit)(ma_context* pContext); ma_result (* onContextEnumerateDevices)(ma_context* pContext, ma_enum_devices_callback_proc callback, void* pUserData); ma_result (* onContextGetDeviceInfo)(ma_context* pContext, ma_device_type deviceType, const ma_device_id* pDeviceID, ma_device_info* pDeviceInfo); ma_result (* onDeviceInit)(ma_device* pDevice, const ma_device_config* pConfig, ma_device_descriptor* pDescriptorPlayback, ma_device_descriptor* pDescriptorCapture); ma_result (* onDeviceUninit)(ma_device* pDevice); ma_result (* onDeviceStart)(ma_device* pDevice); ma_result (* onDeviceStop)(ma_device* pDevice); ma_result (* onDeviceRead)(ma_device* pDevice, void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesRead); ma_result (* onDeviceWrite)(ma_device* pDevice, const void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesWritten); ma_result (* onDeviceDataLoop)(ma_device* pDevice); ma_result (* onDeviceDataLoopWakeup)(ma_device* pDevice); ma_result (* onDeviceGetInfo)(ma_device* pDevice, ma_device_type type, ma_device_info* pDeviceInfo); }; struct ma_context_config { ma_log* pLog; ma_thread_priority threadPriority; size_t threadStackSize; void* pUserData; ma_allocation_callbacks allocationCallbacks; struct { ma_bool32 useVerboseDeviceEnumeration; } alsa; struct { const char* pApplicationName; const char* pServerName; ma_bool32 tryAutoSpawn; /* Enables autospawning of the PulseAudio daemon if necessary. */ } pulse; struct { ma_ios_session_category sessionCategory; ma_uint32 sessionCategoryOptions; ma_bool32 noAudioSessionActivate; /* iOS only.

The config object is initialized with `ma_context_config_init()`. Individual configuration settings can then be set directly on the structure. Below are the members of the `ma_context_config` object. pLog A pointer to the `ma_log` to post log messages to. Can be NULL if the application does not require logging. See the `ma_log` API for details on how to use the logging system. threadPriority The desired priority to use for the audio thread. Allowable values include the following: |--------------------------------------| | Thread Priority | |--------------------------------------| | ma_thread_priority_idle | | ma_thread_priority_lowest | | ma_thread_priority_low | | ma_thread_priority_normal | | ma_thread_priority_high | | ma_thread_priority_highest (default) | | ma_thread_priority_realtime | | ma_thread_priority_default | |--------------------------------------| threadStackSize The desired size of the stack for the audio thread. Defaults to the operating system's default. pUserData A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`. allocationCallbacks Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation callbacks will be used for anything tied to the context, including devices. alsa.useVerboseDeviceEnumeration ALSA will typically enumerate many different devices which can be intrusive and not user-friendly. To combat this, miniaudio will enumerate only unique card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes it so the ALSA backend includes all devices. Defaults to false. pulse.pApplicationName PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`. pulse.pServerName PulseAudio only. The name of the server to connect to with `pa_context_connect()`. pulse.tryAutoSpawn PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be intrusive for the end user. coreaudio.sessionCategory iOS only. The session category to use for the shared AudioSession instance. Below is a list of allowable values and their Core Audio equivalents. |-----------------------------------------|-------------------------------------| | miniaudio Token | Core Audio Token | |-----------------------------------------|-------------------------------------| | ma_ios_session_category_ambient | AVAudioSessionCategoryAmbient | | ma_ios_session_category_solo_ambient | AVAudioSessionCategorySoloAmbient | | ma_ios_session_category_playback | AVAudioSessionCategoryPlayback | | ma_ios_session_category_record | AVAudioSessionCategoryRecord | | ma_ios_session_category_play_and_record | AVAudioSessionCategoryPlayAndRecord | | ma_ios_session_category_multi_route | AVAudioSessionCategoryMultiRoute | | ma_ios_session_category_none | AVAudioSessionCategoryAmbient | | ma_ios_session_category_default | AVAudioSessionCategoryAmbient | |-----------------------------------------|-------------------------------------| coreaudio.sessionCategoryOptions iOS only.

When set to true, does not perform an explicit [[AVAudioSession sharedInstace] setActive:true] on initialization. coreaudio.noAudioSessionDeactivate iOS only. When set to true, does not perform an explicit [[AVAudioSession sharedInstace] setActive:false] on uninitialization. jack.pClientName The name of the client to pass to `jack_client_open()`. jack.tryStartServer Whether or not to try auto-starting the JACK server. Defaults to false. It is recommended that only a single context is active at any given time because it's a bulky data structure which performs run-time linking for the relevant backends every time it's initialized. The location of the context cannot change throughout it's lifetime. Consider allocating the `ma_context` object with `malloc()` if this is an issue. The reason for this is that a pointer to the context is stored in the `ma_device` structure. Example 1 - Default Initialization ---------------------------------- The example below shows how to initialize the context using the default configuration. ```c ma_context context; ma_result result = ma_context_init(NULL, 0, NULL, &context); if (result != MA_SUCCESS) { // Error. } ``` Example 2 - Custom Configuration -------------------------------- The example below shows how to initialize the context using custom backend priorities and a custom configuration. In this hypothetical example, the program wants to prioritize ALSA over PulseAudio on Linux. They also want to avoid using the WinMM backend on Windows because it's latency is too high. They also want an error to be returned if no valid backend is available which they achieve by excluding the Null backend. For the configuration, the program wants to capture any log messages so they can, for example, route it to a log file and user interface. ```c ma_backend backends[] = { ma_backend_alsa, ma_backend_pulseaudio, ma_backend_wasapi, ma_backend_dsound }; ma_log log; ma_log_init(&log); ma_log_register_callback(&log, ma_log_callback_init(my_log_callbac, pMyLogUserData)); ma_context_config config = ma_context_config_init(); config.pLog = &log; // Specify a custom log object in the config so any logs that are posted from ma_context_init() are captured. ma_context context; ma_result result = ma_context_init(backends, sizeof(backends)/sizeof(backends[0]), &config, &context); if (result != MA_SUCCESS) { // Error. if (result == MA_NO_BACKEND) { // Couldn't find an appropriate backend. } } // You could also attach a log callback post-initialization: ma_log_register_callback(ma_context_get_log(&context), ma_log_callback_init(my_log_callback, pMyLogUserData)); ``` See Also -------- ma_context_config_init() ma_context_uninit() */ MA_API ma_result ma_context_init(const ma_backend backends[], ma_uint32 backendCount, const ma_context_config* pConfig, ma_context* pContext); /* Uninitializes a context. Return Value ------------ MA_SUCCESS if successful; any other error code otherwise. Thread Safety ------------- Unsafe. Do not call this function across multiple threads as some backends read and write to global state. Remarks ------- Results are undefined if you call this while any device created by this context is still active.

You can attach your own logging callback to the log with `ma_log_register_callback()` Return Value ------------ A pointer to the `ma_log` object that the context uses to post log messages. If some error occurs, NULL will be returned. */ MA_API ma_log* ma_context_get_log(ma_context* pContext); /* Enumerates over every device (both playback and capture). This is a lower-level enumeration function to the easier to use `ma_context_get_devices()`. Use `ma_context_enumerate_devices()` if you would rather not incur an internal heap allocation, or it simply suits your code better. Note that this only retrieves the ID and name/description of the device. The reason for only retrieving basic information is that it would otherwise require opening the backend device in order to probe it for more detailed information which can be inefficient. Consider using `ma_context_get_device_info()` for this, but don't call it from within the enumeration callback. Returning false from the callback will stop enumeration. Returning true will continue enumeration. Parameters ---------- pContext (in) A pointer to the context performing the enumeration. callback (in) The callback to fire for each enumerated device. pUserData (in) A pointer to application-defined data passed to the callback. Return Value ------------ MA_SUCCESS if successful; any other error code otherwise. Thread Safety ------------- Safe. This is guarded using a simple mutex lock. Remarks ------- Do _not_ assume the first enumerated device of a given type is the default device. Some backends and platforms may only support default playback and capture devices. In general, you should not do anything complicated from within the callback. In particular, do not try initializing a device from within the callback. Also, do not try to call `ma_context_get_device_info()` from within the callback. Consider using `ma_context_get_devices()` for a simpler and safer API, albeit at the expense of an internal heap allocation. Example 1 - Simple Enumeration ------------------------------ ma_bool32 ma_device_enum_callback(ma_context* pContext, ma_device_type deviceType, const ma_device_info* pInfo, void* pUserData) { printf("Device Name: %s\n", pInfo->name); return MA_TRUE; } ma_result result = ma_context_enumerate_devices(&context, my_device_enum_callback, pMyUserData); if (result != MA_SUCCESS) { // Error. } See Also -------- ma_context_get_devices() */ MA_API ma_result ma_context_enumerate_devices(ma_context* pContext, ma_enum_devices_callback_proc callback, void* pUserData); /* Retrieves basic information about every active playback and/or capture device. This function will allocate memory internally for the device lists and return a pointer to them through the `ppPlaybackDeviceInfos` and `ppCaptureDeviceInfos` parameters. If you do not want to incur the overhead of these allocations consider using `ma_context_enumerate_devices()` which will instead use a callback. Parameters ---------- pContext (in) A pointer to the context performing the enumeration. ppPlaybackDeviceInfos (out) A pointer to a pointer that will receive the address of a buffer containing the list of `ma_device_info` structures for playback devices. pPlaybackDeviceCount (out) A pointer to an unsigned integer that will receive the number of playback devices. ppCaptureDeviceInfos (out) A pointer to a pointer that will receive the address of a buffer containing the list of `ma_device_info` structures for capture devices. pCaptureDeviceCount (out) A pointer to an unsigned integer that will receive the number of capture devices. Return Value ------------ MA_SUCCESS if successful; any other error code otherwise. Thread Safety ------------- Unsafe. Since each call to this function invalidates the pointers from the previous call, you should not be calling this simultaneously across multiple threads. Instead, you need to make a copy of the returned data with your own higher level synchronization. Remarks ------- It is _not_ safe to assume the first device in the list is the default device. You can pass in NULL for the playback or capture lists in which case they'll be ignored. The returned pointers will become invalid upon the next call this this function, or when the context is uninitialized. Do not free the returned pointers.

Remarks ------- Do _not_ call this from within the `ma_context_enumerate_devices()` callback. It's possible for a device to have different information and capabilities depending on whether or not it's opened in shared or exclusive mode. For example, in shared mode, WASAPI always uses floating point samples for mixing, but in exclusive mode it can be anything. Therefore, this function allows you to specify which share mode you want information for.

You will typically want to adjust the config after this function returns. See remarks. Thread Safety ------------- Safe. Callback Safety --------------- Safe, but don't try initializing a device in a callback. Remarks ------- The returned config will be initialized to defaults. You will normally want to customize a few variables before initializing the device. See Example 1 for a typical configuration which sets the sample format, channel count, sample rate, data callback and user data. These are usually things you will want to change before initializing the device. See `ma_device_init()` for details on specific configuration options. Example 1 - Simple Configuration -------------------------------- The example below is what a program will typically want to configure for each device at a minimum. Notice how `ma_device_config_init()` is called first, and then the returned object is modified directly. This is important because it ensures that your program continues to work as new configuration options are added to the `ma_device_config` structure. ```c ma_device_config config = ma_device_config_init(ma_device_type_playback); config.playback.format = ma_format_f32; config.playback.channels = 2; config.sampleRate = 48000; config.dataCallback = ma_data_callback; config.pUserData = pMyUserData; ``` See Also -------- ma_device_init() ma_device_init_ex() */ MA_API ma_device_config ma_device_config_init(ma_device_type deviceType); /* Initializes a device. A device represents a physical audio device. The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the device is done via a callback which is fired by miniaudio at periodic time intervals. The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but miniaudio's defaults should work fine for most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple media player you can make it larger. Note that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the backend is ultimately responsible for what it gives you. You cannot assume you will get exactly what you ask for. When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline. Parameters ---------- pContext (in, optional) A pointer to the context that owns the device. This can be null, in which case it creates a default context internally. pConfig (in) A pointer to the device configuration. Cannot be null. See remarks for details. pDevice (out) A pointer to the device object being initialized. Return Value ------------ MA_SUCCESS if successful; any other error code otherwise. Thread Safety ------------- Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to calling this at the same time as `ma_device_uninit()`. Callback Safety --------------- Unsafe. It is not safe to call this inside any callback. Remarks ------- Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so: ```c ma_context_init(NULL, 0, NULL, &context); ``` Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use device.pContext for the initialization of other devices. The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can then be set directly on the structure. Below are the members of the `ma_device_config` object. deviceType Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`. sampleRate The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate. periodSizeInFrames The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will be used depending on the selected performance profile. This value affects latency. See below for details. periodSizeInMilliseconds The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be used depending on the selected performance profile. The value affects latency. See below for details. periods The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured. performanceProfile A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value. noPreSilencedOutputBuffer When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data callback will write to every sample in the output buffer, or if you are doing your own clearing. noClip When set to true, the contents of the output buffer passed into the data callback will be clipped after returning. When set to false (default), the contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or not the clip. This only applies when the playback sample format is f32. noDisableDenormals By default, miniaudio will disable denormals when the data callback is called. Setting this to true will prevent the disabling of denormals. noFixedSizedCallback Allows miniaudio to fire the data callback with any frame count. When this is set to false (the default), the data callback will be fired with a consistent frame count as specified by `periodSizeInFrames` or `periodSizeInMilliseconds`. When set to true, miniaudio will fire the callback with whatever the backend requests, which could be anything. dataCallback The callback to fire whenever data is ready to be delivered to or from the device. notificationCallback The callback to fire when something has changed with the device, such as whether or not it has been started or stopped. pUserData The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`. resampling.algorithm The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`. resampling.pBackendVTable A pointer to an optional vtable that can be used for plugging in a custom resampler. resampling.pBackendUserData A pointer that will passed to callbacks in pBackendVTable. resampling.linear.lpfOrder The linear resampler applies a low-pass filter as part of it's processing for anti-aliasing. This setting controls the order of the filter. The higher the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`. playback.pDeviceID A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. playback.format The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after initialization from the device object directly with `device.playback.format`. playback.channels The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization from the device object directly with `device.playback.channels`. playback.pChannelMap The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the device object direct with `device.playback.pChannelMap`. When set, the buffer should contain `channels` items. playback.shareMode The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to ma_share_mode_shared and reinitializing. capture.pDeviceID A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. capture.format The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after initialization from the device object directly with `device.capture.format`. capture.channels The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization from the device object directly with `device.capture.channels`. capture.pChannelMap The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the device object direct with `device.capture.pChannelMap`. When set, the buffer should contain `channels` items. capture.shareMode The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to ma_share_mode_shared and reinitializing. wasapi.noAutoConvertSRC WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. wasapi.noDefaultQualitySRC WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`. You should usually leave this set to false, which is the default. wasapi.noAutoStreamRouting WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false. wasapi.noHardwareOffloading WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false. alsa.noMMap ALSA only. When set to true, disables MMap mode. Defaults to false. alsa.noAutoFormat ALSA only. When set to true, disables ALSA's automatic format conversion by including the SND_PCM_NO_AUTO_FORMAT flag. Defaults to false. alsa.noAutoChannels ALSA only. When set to true, disables ALSA's automatic channel conversion by including the SND_PCM_NO_AUTO_CHANNELS flag. Defaults to false. alsa.noAutoResample ALSA only. When set to true, disables ALSA's automatic resampling by including the SND_PCM_NO_AUTO_RESAMPLE flag. Defaults to false. pulse.pStreamNamePlayback PulseAudio only. Sets the stream name for playback. pulse.pStreamNameCapture PulseAudio only. Sets the stream name for capture. coreaudio.allowNominalSampleRateChange Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will find the closest match between the sample rate requested in the device config and the sample rates natively supported by the hardware. When set to false, the sample rate currently set by the operating system will always be used. opensl.streamType OpenSL only. Explicitly sets the stream type. If left unset (`ma_opensl_stream_type_default`), the stream type will be left unset. Think of this as the type of audio you're playing. opensl.recordingPreset OpenSL only. Explicitly sets the type of recording your program will be doing. When left unset, the recording preset will be left unchanged. aaudio.usage AAudio only. Explicitly sets the nature of the audio the program will be consuming. When left unset, the usage will be left unchanged. aaudio.contentType AAudio only. Sets the content type. When left unset, the content type will be left unchanged. aaudio.inputPreset AAudio only. Explicitly sets the type of recording your program will be doing. When left unset, the input preset will be left unchanged. aaudio.noAutoStartAfterReroute AAudio only. Controls whether or not the device should be automatically restarted after a stream reroute. When set to false (default) the device will be restarted automatically; otherwise the device will be stopped. Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device. After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`. If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or `ma_performance_profile_conservative`. If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA, for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user. Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary. When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`, `playback/capture.channels` and `sampleRate` members of the device object. When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information. ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture. If these fail it will try falling back to the "hw" device. Example 1 - Simple Initialization --------------------------------- This example shows how to initialize a simple playback device using a standard configuration. If you are just needing to do simple playback from the default playback device this is usually all you need. ```c ma_device_config config = ma_device_config_init(ma_device_type_playback); config.playback.format = ma_format_f32; config.playback.channels = 2; config.sampleRate = 48000; config.dataCallback = ma_data_callback; config.pMyUserData = pMyUserData; ma_device device; ma_result result = ma_device_init(NULL, &config, &device); if (result != MA_SUCCESS) { // Error } ``` Example 2 - Advanced Initialization ----------------------------------- This example shows how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size and period count. We also want to allow the user to be able to choose which device to output from which means we need a context so we can perform device enumeration. ```c ma_context context; ma_result result = ma_context_init(NULL, 0, NULL, &context); if (result != MA_SUCCESS) { // Error } ma_device_info* pPlaybackDeviceInfos; ma_uint32 playbackDeviceCount; result = ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, NULL, NULL); if (result != MA_SUCCESS) { // Error } // ... choose a device from pPlaybackDeviceInfos ... ma_device_config config = ma_device_config_init(ma_device_type_playback); config.playback.pDeviceID = pMyChosenDeviceID; // <-- Get this from the `id` member of one of the `ma_device_info` objects returned by ma_context_get_devices(). config.playback.format = ma_format_f32; config.playback.channels = 2; config.sampleRate = 48000; config.dataCallback = ma_data_callback; config.pUserData = pMyUserData; config.periodSizeInMilliseconds = 10; config.periods = 3; ma_device device; result = ma_device_init(&context, &config, &device); if (result != MA_SUCCESS) { // Error } ``` See Also -------- ma_device_config_init() ma_device_uninit() ma_device_start() ma_context_init() ma_context_get_devices() ma_context_enumerate_devices() */ MA_API ma_result ma_device_init(ma_context* pContext, const ma_device_config* pConfig, ma_device* pDevice); /* Initializes a device without a context, with extra parameters for controlling the configuration of the internal self-managed context.

Remarks ------- This API needs to wait on the worker thread to stop the backend device properly before returning. It also waits on a mutex for thread-safety.

Backends are required to either pause the stream in-place or drain the buffer if pausing is not possible. The reason for this is that stopping the device and the resuming it with ma_device_start() (which you might do when your program loses focus) may result in a situation where those samples are never output to the speakers or received from the microphone which can in turn result in de-syncs.

This function is used by backends for helping determine an appropriately sized buffer to use with the device depending on the values of `periodSizeInFrames` and `periodSizeInMilliseconds` in the `pDescriptor` object. Since buffer size calculations based on time depends on the sample rate, a best guess at the device's native sample rate is also required which is where `nativeSampleRate` comes in. In addition, the performance profile is also needed for cases where both the period size in frames and milliseconds are both zero. Parameters ---------- pDescriptor (in) A pointer to device descriptor whose `periodSizeInFrames` and `periodSizeInMilliseconds` members will be used for the calculation of the buffer size. nativeSampleRate (in) The device's native sample rate. This is only ever used when the `periodSizeInFrames` member of `pDescriptor` is zero. In this case, `periodSizeInMilliseconds` will be used instead, in which case a sample rate is required to convert to a size in frames. performanceProfile (in) When both the `periodSizeInFrames` and `periodSizeInMilliseconds` members of `pDescriptor` are zero, miniaudio will fall back to a buffer size based on the performance profile. The profile to use for this calculation is determine by this parameter. Return Value ------------ The calculated buffer size in frames.

If `MA_NO_SPACE` is returned, the `pBackends` buffer will be filled with `*pBackendCount` values. Thread Safety ------------- Safe. Callback Safety --------------- Safe. Remarks ------- If you want to retrieve the number of backends so you can determine the capacity of `pBackends` buffer, you can call this function with `pBackends` set to NULL. This will also enumerate the null backend. If you don't want to include this you need to check for `ma_backend_null` when you enumerate over the returned backends and handle it appropriately. Alternatively, you can disable it at compile time with `MA_NO_NULL`. The returned backends are determined based on compile time settings, not the platform it's currently running on. For example, PulseAudio will be returned if it was enabled at compile time, even when the user doesn't actually have PulseAudio installed. Example 1 --------- The example below retrieves the enabled backend count using a fixed sized buffer allocated on the stack. The buffer is given a capacity of `MA_BACKEND_COUNT` which will guarantee it'll be large enough to store all available backends.

You will notice skipping/crackling in the audio, and it'll run at a slightly faster rate. miniaudio has built-in support for sample rate conversion (albeit low quality at the moment), so disabling resampling should be fine for us. The only problem is that it won't be taking advantage of any kind of hardware-accelerated resampling and it won't be very good quality until I get a chance to improve the quality of miniaudio's software sample rate conversion. I don't currently know if the dmix plugin is the only one with this error. Indeed, this is the only one I've been able to reproduce this error with. In the future, we may want to restrict the disabling of resampling to only known bad plugins. */ ((ma_snd_pcm_hw_params_set_rate_resample_proc)pDevice->pContext->alsa.snd_pcm_hw_params_set_rate_resample)(pPCM, pHWParams, 0); sampleRate = pDescriptor->sampleRate; if (sampleRate == 0) { sampleRate = MA_DEFAULT_SAMPLE_RATE; } resultALSA = ((ma_snd_pcm_hw_params_set_rate_near_proc)pDevice->pContext->alsa.snd_pcm_hw_params_set_rate_near)(pPCM, pHWParams, &sampleRate, 0); if (resultALSA < 0) { ma_free(pHWParams, &pDevice->pContext->allocationCallbacks); ((ma_snd_pcm_close_proc)pDevice->pContext->alsa.snd_pcm_close)(pPCM); ma_log_post(ma_device_get_log(pDevice), MA_LOG_LEVEL_ERROR, "[ALSA] Sample rate not supported. snd_pcm_hw_params_set_rate_near() failed."); return ma_result_from_errno(-resultALSA); } internalSampleRate = (ma_uint32)sampleRate; } /* Periods. */ { ma_uint32 periods = pDescriptor->periodCount; resultALSA = ((ma_snd_pcm_hw_params_set_periods_near_proc)pDevice->pContext->alsa.snd_pcm_hw_params_set_periods_near)(pPCM, pHWParams, &periods, NULL); if (resultALSA < 0) { ma_free(pHWParams, &pDevice->pContext->allocationCallbacks); ((ma_snd_pcm_close_proc)pDevice->pContext->alsa.snd_pcm_close)(pPCM); ma_log_post(ma_device_get_log(pDevice), MA_LOG_LEVEL_ERROR, "[ALSA] Failed to set period count. snd_pcm_hw_params_set_periods_near() failed."); return ma_result_from_errno(-resultALSA); } internalPeriods = periods; } /* Buffer Size */ { ma_snd_pcm_uframes_t actualBufferSizeInFrames = ma_calculate_buffer_size_in_frames_from_descriptor(pDescriptor, internalSampleRate, pConfig->performanceProfile) * internalPeriods; resultALSA = ((ma_snd_pcm_hw_params_set_buffer_size_near_proc)pDevice->pContext->alsa.snd_pcm_hw_params_set_buffer_size_near)(pPCM, pHWParams, &actualBufferSizeInFrames); if (resultALSA < 0) { ma_free(pHWParams, &pDevice->pContext->allocationCallbacks); ((ma_snd_pcm_close_proc)pDevice->pContext->alsa.snd_pcm_close)(pPCM); ma_log_post(ma_device_get_log(pDevice), MA_LOG_LEVEL_ERROR, "[ALSA] Failed to set buffer size for device. snd_pcm_hw_params_set_buffer_size() failed."); return ma_result_from_errno(-resultALSA); } internalPeriodSizeInFrames = actualBufferSizeInFrames / internalPeriods; } /* Apply hardware parameters. */ resultALSA = ((ma_snd_pcm_hw_params_proc)pDevice->pContext->alsa.snd_pcm_hw_params)(pPCM, pHWParams); if (resultALSA < 0) { ma_free(pHWParams, &pDevice->pContext->allocationCallbacks); ((ma_snd_pcm_close_proc)pDevice->pContext->alsa.snd_pcm_close)(pPCM); ma_log_post(ma_device_get_log(pDevice), MA_LOG_LEVEL_ERROR, "[ALSA] Failed to set hardware parameters. snd_pcm_hw_params() failed."); return ma_result_from_errno(-resultALSA); } ma_free(pHWParams, &pDevice->pContext->allocationCallbacks); pHWParams = NULL; /* Software parameters. */ pSWParams = (ma_snd_pcm_sw_params_t*)ma_calloc(((ma_snd_pcm_sw_params_sizeof_proc)pDevice->pContext->alsa.snd_pcm_sw_params_sizeof)(), &pDevice->pContext->allocationCallbacks); if (pSWParams == NULL) { ((ma_snd_pcm_close_proc)pDevice->pContext->alsa.snd_pcm_close)(pPCM); ma_log_post(ma_device_get_log(pDevice), MA_LOG_LEVEL_ERROR, "[ALSA] Failed to allocate memory for software parameters."); return MA_OUT_OF_MEMORY; } resultALSA = ((ma_snd_pcm_sw_params_current_proc)pDevice->pContext->alsa.snd_pcm_sw_params_current)(pPCM, pSWParams); if (resultALSA < 0) { ma_free(pSWParams, &pDevice->pContext->allocationCallbacks); ((ma_snd_pcm_close_proc)pDevice->pContext->alsa.snd_pcm_close)(pPCM); ma_log_post(ma_device_get_log(pDevice), MA_LOG_LEVEL_ERROR, "[ALSA] Failed to initialize software parameters. snd_pcm_sw_params_current() failed."); return ma_result_from_errno(-resultALSA); } resultALSA = ((ma_snd_pcm_sw_params_set_avail_min_proc)pDevice->pContext->alsa.snd_pcm_sw_params_set_avail_min)(pPCM, pSWParams, ma_prev_power_of_2(internalPeriodSizeInFrames)); if (resultALSA < 0) { ma_free(pSWParams, &pDevice->pContext->allocationCallbacks); ((ma_snd_pcm_close_proc)pDevice->pContext->alsa.snd_pcm_close)(pPCM); ma_log_post(ma_device_get_log(pDevice), MA_LOG_LEVEL_ERROR, "[ALSA] snd_pcm_sw_params_set_avail_min() failed."); return ma_result_from_errno(-resultALSA); } resultALSA = ((ma_snd_pcm_sw_params_get_boundary_proc)pDevice->pContext->alsa.snd_pcm_sw_params_get_boundary)(pSWParams, &bufferBoundary); if (resultALSA < 0) { bufferBoundary = internalPeriodSizeInFrames * internalPeriods; } if (deviceType == ma_device_type_playback && !isUsingMMap) { /* Only playback devices in writei/readi mode need a start threshold. */ /* Subtle detail here with the start threshold.

This is a brief description of what's going on in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion. PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API. Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to get fun, and I don't mean that in a good way... The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is enabled through the use of a "main loop". In the asychronous API you cannot get away from the main loop, and the main loop is where almost all of PulseAudio's problems stem from. When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed. To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely specialized such as if you want to integrate it into your application's existing main loop infrastructure. (EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262. It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.) Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()` has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop. All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected. This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`. The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind. Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device. The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call `pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up. All of that just to retrieve basic information about a device! Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design choices in PulseAudio. PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified, PulseAudio will immediately fire it's write or read callback. This is *technically* correct (based on the wording in the documentation) because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback would be where a program will want to write or read data to or from the stream, but when it's called before the application has even requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been started. The device state is used for this - if the state is anything other than `ma_device_state_starting` or `ma_device_state_started`, the main data callback is not fired. This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call `pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to *not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again! This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not* write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.) Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context, only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as "corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is absolutely beyond me. Would it really be that hard to just make it run synchronously? Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that they were initialized in. That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These changes alone will change PulseAudio from one of the worst audio APIs to one of the best. */ /* It is assumed pulseaudio.h is available when linking at compile time.

#endif /* Core Audio So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose needing to figure out how this darn thing works, I'm going to outline a few things here. Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API. Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be the central APIs for retrieving information about the system and specific devices. To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a structure with three variables and is used to identify which property you are getting or setting. The first is the "selector" which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to kAudioObjectPropertyElementMain in miniaudio's case. I don't know of any cases where this would be set to anything different. Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count. */ static ma_result ma_result_from_OSStatus(OSStatus status) { switch (status) { case noErr: return MA_SUCCESS;

Typically, this means that a client can specify ANY variant of the PCM formats. Consequently, the device's sample rate should match the desired sample rate. If sample rate conversion is needed, it can be accomplished by buffering the input and converting the data on a separate thread with another AudioConverter. The important part here is the mention that it can handle *simple* conversions, which does *not* include sample rate. We therefore want to ensure the sample rate stays consistent. This document is specifically for input, but I'm going to play it safe and apply the same rule to output as well. I have tried going against the documentation by setting the sample rate anyway, but this just results in AudioUnitRender() returning a result code of -10863. I have also tried changing the format directly on the input scope on the input bus, but this just results in `ca_require: IsStreamFormatWritable(inScope, inElement) NotWritable` when trying to set the format. Something that does seem to work, however, has been setting the nominal sample rate on the deivce object. The problem with this, however, is that it actually changes the sample rate at the operating system level and not just the application. This could be intrusive to the user, however, so I don't think it's wise to make this the default. Instead I'm making this a configuration option. When the `coreaudio.allowNominalSampleRateChange` config option is set to true, changing the sample rate will be allowed. Otherwise it'll be fixed to the current sample rate. To check the system-defined sample rate, run the Audio MIDI Setup program that comes installed on macOS and observe how the sample rate changes as the sample rate is changed by miniaudio. */ if (pData->allowNominalSampleRateChange) { AudioValueRange sampleRateRange; AudioObjectPropertyAddress propAddress; sampleRateRange.mMinimum = bestFormat.mSampleRate; sampleRateRange.mMaximum = bestFormat.mSampleRate; propAddress.mSelector = kAudioDevicePropertyNominalSampleRate; propAddress.mScope = (deviceType == ma_device_type_playback) ? kAudioObjectPropertyScopeOutput : kAudioObjectPropertyScopeInput; propAddress.mElement = AUDIO_OBJECT_PROPERTY_ELEMENT; status = ((ma_AudioObjectSetPropertyData_proc)pContext->coreaudio.AudioObjectSetPropertyData)(deviceObjectID, &propAddress, 0, NULL, sizeof(sampleRateRange), &sampleRateRange); if (status != noErr) { bestFormat.mSampleRate = origFormat.mSampleRate; } } else { bestFormat.mSampleRate = origFormat.mSampleRate; } status = ((ma_AudioUnitSetProperty_proc)pContext->coreaudio.AudioUnitSetProperty)(pData->audioUnit, kAudioUnitProperty_StreamFormat, formatScope, formatElement, &bestFormat, sizeof(bestFormat)); if (status != noErr) { /* We failed to set the format, so fall back to the current format of the audio unit. */ bestFormat = origFormat; } #else bestFormat = origFormat; /* Sample rate is a little different here because for some reason kAudioUnitProperty_StreamFormat returns 0...

Not only does this feel uncomfortable, it doesn't even remotely represent the real world at all because sounds that come from your right side are still clearly audible from your left side. Setting "dMin" to 1 will result in no panning at all, which is also not ideal. By setting it to something greater than 0, the spatialization effect becomes much less dramatic and a lot more bearable.

It will be in the range of -1..1. There's two ways I can think of to calculate a panning value. The first is to simply convert it to 0..1, however this has a problem which I'm not entirely happy with. Considering a stereo system, when a sound is positioned right in front of the listener it'll result in each speaker getting a gain of 0.5. I don't know if I like the idea of having a scaling factor of 0.5 being applied to a sound when it's sitting right in front of the listener. I would intuitively expect that to be played at full volume, or close to it. The second idea I think of is to only apply a reduction in gain when the sound is on the opposite side of the speaker. That is, reduce the gain only when the dot product is negative. The problem with this is that there will not be any attenuation as the sound sweeps around the 180 degrees where the dot product is positive. The idea with this option is that you leave the gain at 1 when the sound is being played on the same side as the speaker and then you just reduce the volume when the sound is on the other side. The summarize, I think the first option should give a better sense of spatialization, but the second option is better for preserving the sound's power.

You can feel the sense of space a bit better, but you can also hear the reduction in volume when it's right in front. */ #if 1 { /* Scale the dot product from -1..1 to 0..1.

The amount of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated. Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works across 3 spatial dimensions. The first thing to do is figure out how each speaker's volume is spread over each of plane: - front/left: 2 planes (front and left) = 1/2 = half it's total volume on each plane - side/left: 1 plane (left only) = 1/1 = entire volume from left plane - back/left: 2 planes (back and left) = 1/2 = half it's total volume on each plane - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be taken by the other to produce the final contribution. */ /* Contribution = Sum(Volume to Give * Volume to Take) */ float contribution = g_maChannelPlaneRatios[channelPositionA][0] * g_maChannelPlaneRatios[channelPositionB][0] + g_maChannelPlaneRatios[channelPositionA][1] * g_maChannelPlaneRatios[channelPositionB][1] + g_maChannelPlaneRatios[channelPositionA][2] * g_maChannelPlaneRatios[channelPositionB][2] + g_maChannelPlaneRatios[channelPositionA][3] * g_maChannelPlaneRatios[channelPositionB][3] + g_maChannelPlaneRatios[channelPositionA][4] * g_maChannelPlaneRatios[channelPositionB][4] + g_maChannelPlaneRatios[channelPositionA][5] * g_maChannelPlaneRatios[channelPositionB][5]; return contribution; } MA_API ma_channel_converter_config ma_channel_converter_config_init(ma_format format, ma_uint32 channelsIn, const ma_channel* pChannelMapIn, ma_uint32 channelsOut, const ma_channel* pChannelMapOut, ma_channel_mix_mode mixingMode) { ma_channel_converter_config config; MA_ZERO_OBJECT(&config); config.format = format; config.channelsIn = channelsIn; config.channelsOut = channelsOut; config.pChannelMapIn = pChannelMapIn; config.pChannelMapOut = pChannelMapOut; config.mixingMode = mixingMode; return config; } static ma_int32 ma_channel_converter_float_to_fixed(float x) { return (ma_int32)(x * (1< 0); for (iChannel = 0; iChannel < channels; ++iChannel) { if (ma_is_spatial_channel_position(ma_channel_map_get_channel(pChannelMap, channels, iChannel))) { spatialChannelCount++; } } return spatialChannelCount; } static ma_bool32 ma_is_spatial_channel_position(ma_channel channelPosition) { int i; if (channelPosition == MA_CHANNEL_NONE || channelPosition == MA_CHANNEL_MONO || channelPosition == MA_CHANNEL_LFE) { return MA_FALSE; } if (channelPosition >= MA_CHANNEL_AUX_0 && channelPosition <= MA_CHANNEL_AUX_31) { return MA_FALSE; } for (i = 0; i < 6; ++i) { /* Each side of a cube. */ if (g_maChannelPlaneRatios[channelPosition][i] != 0) { return MA_TRUE; } } return MA_FALSE; } static ma_bool32 ma_channel_map_is_passthrough(const ma_channel* pChannelMapIn, ma_uint32 channelsIn, const ma_channel* pChannelMapOut, ma_uint32 channelsOut) { if (channelsOut == channelsIn) { return ma_channel_map_is_equal(pChannelMapOut, pChannelMapIn, channelsOut); } else { return MA_FALSE; /* Channel counts differ, so cannot be a passthrough. */ } } static ma_channel_conversion_path ma_channel_map_get_conversion_path(const ma_channel* pChannelMapIn, ma_uint32 channelsIn, const ma_channel* pChannelMapOut, ma_uint32 channelsOut, ma_channel_mix_mode mode) { if (ma_channel_map_is_passthrough(pChannelMapIn, channelsIn, pChannelMapOut, channelsOut)) { return ma_channel_conversion_path_passthrough; } if (channelsOut == 1 && (pChannelMapOut == NULL || pChannelMapOut[0] == MA_CHANNEL_MONO)) { return ma_channel_conversion_path_mono_out; } if (channelsIn == 1 && (pChannelMapIn == NULL || pChannelMapIn[0] == MA_CHANNEL_MONO)) { return ma_channel_conversion_path_mono_in; } if (mode == ma_channel_mix_mode_custom_weights) { return ma_channel_conversion_path_weights; } /* We can use a simple shuffle if both channel maps have the same channel count and all channel positions are present in both. */ if (channelsIn == channelsOut) { ma_uint32 iChannelIn; ma_bool32 areAllChannelPositionsPresent = MA_TRUE; for (iChannelIn = 0; iChannelIn < channelsIn; ++iChannelIn) { ma_bool32 isInputChannelPositionInOutput = MA_FALSE; if (ma_channel_map_contains_channel_position(channelsOut, pChannelMapOut, ma_channel_map_get_channel(pChannelMapIn, channelsIn, iChannelIn))) { isInputChannelPositionInOutput = MA_TRUE; break; } if (!isInputChannelPositionInOutput) { areAllChannelPositionsPresent = MA_FALSE; break; } } if (areAllChannelPositionsPresent) { return ma_channel_conversion_path_shuffle; } } /* Getting here means we'll need to use weights. */ return ma_channel_conversion_path_weights; } static ma_result ma_channel_map_build_shuffle_table(const ma_channel* pChannelMapIn, ma_uint32 channelCountIn, const ma_channel* pChannelMapOut, ma_uint32 channelCountOut, ma_uint8* pShuffleTable) { ma_uint32 iChannelIn; ma_uint32 iChannelOut; if (pShuffleTable == NULL || channelCountIn == 0 || channelCountOut == 0) { return MA_INVALID_ARGS; } /* When building the shuffle table we just do a 1:1 mapping based on the first occurance of a channel.

I think it's got something to do with the single- threaded nature of Web, but I'm not entirely sure. */ #if !defined(MA_NO_RESOURCE_MANAGER) && defined(MA_EMSCRIPTEN) { if (pEngine->pResourceManager != NULL) { if ((pEngine->pResourceManager->config.flags & MA_RESOURCE_MANAGER_FLAG_NO_THREADING) != 0) { ma_resource_manager_process_next_job(pEngine->pResourceManager); } } } #endif ma_engine_read_pcm_frames(pEngine, pFramesOut, frameCount, NULL); } #endif MA_API ma_result ma_engine_init(const ma_engine_config* pConfig, ma_engine* pEngine) { ma_result result; ma_node_graph_config nodeGraphConfig; ma_engine_config engineConfig; ma_spatializer_listener_config listenerConfig; ma_uint32 iListener; if (pEngine == NULL) { return MA_INVALID_ARGS; } MA_ZERO_OBJECT(pEngine); /* The config is allowed to be NULL in which case we use defaults for everything. */ if (pConfig != NULL) { engineConfig = *pConfig; } else { engineConfig = ma_engine_config_init(); } pEngine->monoExpansionMode = engineConfig.monoExpansionMode; pEngine->defaultVolumeSmoothTimeInPCMFrames = engineConfig.defaultVolumeSmoothTimeInPCMFrames; pEngine->onProcess = engineConfig.onProcess; pEngine->pProcessUserData = engineConfig.pProcessUserData; ma_allocation_callbacks_init_copy(&pEngine->allocationCallbacks, &engineConfig.allocationCallbacks); #if !defined(MA_NO_RESOURCE_MANAGER) { pEngine->pResourceManager = engineConfig.pResourceManager; } #endif #if !defined(MA_NO_DEVICE_IO) { pEngine->pDevice = engineConfig.pDevice; /* If we don't have a device, we need one. */ if (pEngine->pDevice == NULL && engineConfig.noDevice == MA_FALSE) { ma_device_config deviceConfig; pEngine->pDevice = (ma_device*)ma_malloc(sizeof(*pEngine->pDevice), &pEngine->allocationCallbacks); if (pEngine->pDevice == NULL) { return MA_OUT_OF_MEMORY; } deviceConfig = ma_device_config_init(ma_device_type_playback); deviceConfig.playback.pDeviceID = engineConfig.pPlaybackDeviceID; deviceConfig.playback.format = ma_format_f32; deviceConfig.playback.channels = engineConfig.channels; deviceConfig.sampleRate = engineConfig.sampleRate; deviceConfig.dataCallback = (engineConfig.dataCallback != NULL) ? engineConfig.dataCallback : ma_engine_data_callback_internal; deviceConfig.pUserData = pEngine; deviceConfig.notificationCallback = engineConfig.notificationCallback; deviceConfig.periodSizeInFrames = engineConfig.periodSizeInFrames; deviceConfig.periodSizeInMilliseconds = engineConfig.periodSizeInMilliseconds; deviceConfig.noPreSilencedOutputBuffer = MA_TRUE; /* We'll always be outputting to every frame in the callback so there's no need for a pre-silenced buffer. */ deviceConfig.noClip = MA_TRUE; /* The engine will do clipping itself. */ if (engineConfig.pContext == NULL) { ma_context_config contextConfig = ma_context_config_init(); contextConfig.allocationCallbacks = pEngine->allocationCallbacks; contextConfig.pLog = engineConfig.pLog; /* If the engine config does not specify a log, use the resource manager's if we have one. */ #ifndef MA_NO_RESOURCE_MANAGER { if (contextConfig.pLog == NULL && engineConfig.pResourceManager != NULL) { contextConfig.pLog = ma_resource_manager_get_log(engineConfig.pResourceManager); } } #endif result = ma_device_init_ex(NULL, 0, &contextConfig, &deviceConfig, pEngine->pDevice); } else { result = ma_device_init(engineConfig.pContext, &deviceConfig, pEngine->pDevice); } if (result != MA_SUCCESS) { ma_free(pEngine->pDevice, &pEngine->allocationCallbacks); pEngine->pDevice = NULL; return result; } pEngine->ownsDevice = MA_TRUE; } /* Update the channel count and sample rate of the engine config so we can reference it below. */ if (pEngine->pDevice != NULL) { engineConfig.channels = pEngine->pDevice->playback.channels; engineConfig.sampleRate = pEngine->pDevice->sampleRate; } } #endif if (engineConfig.channels == 0 || engineConfig.sampleRate == 0) { return MA_INVALID_ARGS; } pEngine->sampleRate = engineConfig.sampleRate; /* The engine always uses either the log that was passed into the config, or the context's log is available. */ if (engineConfig.pLog != NULL) { pEngine->pLog = engineConfig.pLog; } else { #if !defined(MA_NO_DEVICE_IO) { pEngine->pLog = ma_device_get_log(pEngine->pDevice); } #else { pEngine->pLog = NULL; } #endif } /* The engine is a node graph.

Lua is a powerful, efficient, lightweight, embeddable scripting language.

(It produces false and skips the next instruction producing true.) (*) Opcodes OP_MMBIN and variants follow each arithmetic and bitwise opcode. If the operation succeeds, it skips this next opcode. Otherwise, this opcode calls the corresponding metamethod. (*) Opcode OP_TESTSET is used in short-circuit expressions that need both to jump and to produce a value, such as (a = b or c). (*) In OP_CALL, if (B == 0) then B = top - A. If (C == 0), then 'top' is set to last_result+1, so next open instruction (OP_CALL, OP_RETURN*, OP_SETLIST) may use 'top'. (*) In OP_VARARG, if (C == 0) then use actual number of varargs and set top (like in OP_CALL with C == 0). (*) In OP_RETURN, if (B == 0) then return up to 'top'. (*) In OP_LOADKX and OP_NEWTABLE, the next instruction is always OP_EXTRAARG. (*) In OP_SETLIST, if (B == 0) then real B = 'top'; if k, then real C = EXTRAARG _ C (the bits of EXTRAARG concatenated with the bits of C). (*) In OP_NEWTABLE, B is log2 of the hash size (which is always a power of 2) plus 1, or zero for size zero. If not k, the array size is C. Otherwise, the array size is EXTRAARG _ C. (*) For comparisons, k specifies what condition the test should accept (true or false). (*) In OP_MMBINI/OP_MMBINK, k means the arguments were flipped (the constant is the first operand). (*) All 'skips' (pc++) assume that next instruction is a jump. (*) In instructions OP_RETURN/OP_TAILCALL, 'k' specifies that the function builds upvalues, which may need to be closed. C > 0 means the function is vararg, so that its 'func' must be corrected before returning; in this case, (C - 1) is its number of fixed parameters. (*) In comparisons with an immediate operand, C signals whether the original operand was a float. (It must be corrected in case of metamethods.) ===========================================================================*/ /* ** masks for instruction properties.

The pixel data consists of *y scanlines of *x pixels, // with each pixel consisting of N interleaved 8-bit components; the first // pixel pointed to is top-left-most in the image. There is no padding between // image scanlines or between pixels, regardless of format. The number of // components N is 'desired_channels' if desired_channels is non-zero, or // *channels_in_file otherwise. If desired_channels is non-zero, // *channels_in_file has the number of components that _would_ have been // output otherwise. E.g. if you set desired_channels to 4, you will always // get RGBA output, but you can check *channels_in_file to see if it's trivially // opaque because e.g. there were only 3 channels in the source image. // // An output image with N components has the following components interleaved // in this order in each pixel: // // N=#comp components // 1 grey // 2 grey, alpha // 3 red, green, blue // 4 red, green, blue, alpha // // If image loading fails for any reason, the return value will be NULL, // and *x, *y, *channels_in_file will be unchanged. The function // stbi_failure_reason() can be queried for an extremely brief, end-user // unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS // to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly // more user-friendly ones. // // Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. // // To query the width, height and component count of an image without having to // decode the full file, you can use the stbi_info family of functions: // // int x,y,n,ok; // ok = stbi_info(filename, &x, &y, &n); // // returns ok=1 and sets x, y, n if image is a supported format, // // 0 otherwise. // // Note that stb_image pervasively uses ints in its public API for sizes, // including sizes of memory buffers. This is now part of the API and thus // hard to change without causing breakage. As a result, the various image // loaders all have certain limits on image size; these differ somewhat // by format but generally boil down to either just under 2GB or just under // 1GB. When the decoded image would be larger than this, stb_image decoding // will fail. // // Additionally, stb_image will reject image files that have any of their // dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, // which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, // the only way to have an image with such dimensions load correctly // is for it to have a rather extreme aspect ratio. Either way, the // assumption here is that such larger images are likely to be malformed // or malicious. If you do need to load an image with individual dimensions // larger than that, and it still fits in the overall size limit, you can // #define STBI_MAX_DIMENSIONS on your own to be something larger. // // =========================================================================== // // UNICODE: // // If compiling for Windows and you wish to use Unicode filenames, compile // with // #define STBI_WINDOWS_UTF8 // and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert // Windows wchar_t filenames to utf8. // // =========================================================================== // // Philosophy // // stb libraries are designed with the following priorities: // // 1. easy to use // 2. easy to maintain // 3. good performance // // Sometimes I let "good performance" creep up in priority over "easy to maintain", // and for best performance I may provide less-easy-to-use APIs that give higher // performance, in addition to the easy-to-use ones. Nevertheless, it's important // to keep in mind that from the standpoint of you, a client of this library, // all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. // // Some secondary priorities arise directly from the first two, some of which // provide more explicit reasons why performance can't be emphasized. // // - Portable ("ease of use") // - Small source code footprint ("easy to maintain") // - No dependencies ("ease of use") // // =========================================================================== // // I/O callbacks // // I/O callbacks allow you to read from arbitrary sources, like packaged // files or some other source. Data read from callbacks are processed // through a small internal buffer (currently 128 bytes) to try to reduce // overhead. // // The three functions you must define are "read" (reads some bytes of data), // "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). // // =========================================================================== // // SIMD support // // The JPEG decoder will try to automatically use SIMD kernels on x86 when // supported by the compiler. For ARM Neon support, you must explicitly // request it. // // (The old do-it-yourself SIMD API is no longer supported in the current // code.) // // On x86, SSE2 will automatically be used when available based on a run-time // test; if not, the generic C versions are used as a fall-back. On ARM targets, // the typical path is to have separate builds for NEON and non-NEON devices // (at least this is true for iOS and Android). Therefore, the NEON support is // toggled by a build flag: define STBI_NEON to get NEON loops. // // If for some reason you do not want to use any of SIMD code, or if // you have issues compiling it, you can disable it entirely by // defining STBI_NO_SIMD. // // =========================================================================== // // HDR image support (disable by defining STBI_NO_HDR) // // stb_image supports loading HDR images in general, and currently the Radiance // .HDR file format specifically. You can still load any file through the existing // interface; if you attempt to load an HDR file, it will be automatically remapped // to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; // both of these constants can be reconfigured through this interface: // // stbi_hdr_to_ldr_gamma(2.2f); // stbi_hdr_to_ldr_scale(1.0f); // // (note, do not use _inverse_ constants; stbi_image will invert them // appropriately). // // Additionally, there is a new, parallel interface for loading files as // (linear) floats to preserve the full dynamic range: // // float *data = stbi_loadf(filename, &x, &y, &n, 0); // // If you load LDR images through this interface, those images will // be promoted to floating point values, run through the inverse of // constants corresponding to the above: // // stbi_ldr_to_hdr_scale(1.0f); // stbi_ldr_to_hdr_gamma(2.2f); // // Finally, given a filename (or an open file or memory block--see header // file for details) containing image data, you can query for the "most // appropriate" interface to use (that is, whether the image is HDR or // not), using: // // stbi_is_hdr(char *filename); // // =========================================================================== // // iPhone PNG support: // // We optionally support converting iPhone-formatted PNGs (which store // premultiplied BGRA) back to RGB, even though they're internally encoded // differently. To enable this conversion, call // stbi_convert_iphone_png_to_rgb(1). // // Call stbi_set_unpremultiply_on_load(1) as well to force a divide per // pixel to remove any premultiplied alpha *only* if the image file explicitly // says there's premultiplied data (currently only happens in iPhone images, // and only if iPhone convert-to-rgb processing is on). // // =========================================================================== // // ADDITIONAL CONFIGURATION // // - You can suppress implementation of any of the decoders to reduce // your code footprint by #defining one or more of the following // symbols before creating the implementation. // // STBI_NO_JPEG // STBI_NO_PNG // STBI_NO_BMP // STBI_NO_PSD // STBI_NO_TGA // STBI_NO_GIF // STBI_NO_HDR // STBI_NO_PIC // STBI_NO_PNM (.ppm and .pgm) // // - You can request *only* certain decoders and suppress all other ones // (this will be more forward-compatible, as addition of new decoders // doesn't require you to disable them explicitly): // // STBI_ONLY_JPEG // STBI_ONLY_PNG // STBI_ONLY_BMP // STBI_ONLY_PSD // STBI_ONLY_TGA // STBI_ONLY_GIF // STBI_ONLY_HDR // STBI_ONLY_PIC // STBI_ONLY_PNM (.ppm and .pgm) // // - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still // want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB // // - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater // than that size (in either width or height) without further processing. // This is to let programs in the wild set an upper bound to prevent // denial-of-service attacks on untrusted data, as one could generate a // valid image of gigantic dimensions and force stb_image to allocate a // huge block of memory and spend disproportionate time decoding it.

Will probably not work correctly with strict-aliasing optimizations. ABOUT: This header file is a library for writing images to C stdio or a callback. The PNG output is not optimal; it is 20-50% larger than the file written by a decent optimizing implementation; though providing a custom zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that. This library is designed for source code compactness and simplicity, not optimal image file size or run-time performance. BUILDING: You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h. You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace malloc,realloc,free. You can #define STBIW_MEMMOVE() to replace memmove() You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function for PNG compression (instead of the builtin one), it must have the following signature: unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality); The returned data will be freed with STBIW_FREE() (free() by default), so it must be heap allocated with STBIW_MALLOC() (malloc() by default), UNICODE: If compiling for Windows and you wish to use Unicode filenames, compile with #define STBIW_WINDOWS_UTF8 and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert Windows wchar_t filenames to utf8. USAGE: There are five functions, one for each image file format: int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality); int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically There are also five equivalent functions that use an arbitrary write function. You are expected to open/close your file-equivalent before and after calling these: int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality); where the callback is: void stbi_write_func(void *context, void *data, int size); You can configure it with these global variables: int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode You can define STBI_WRITE_NO_STDIO to disable the file variant of these functions, so the library will not use stdio.h at all. However, this will also disable HDR writing, because it requires stdio for formatted output. Each function returns 0 on failure and non-0 on success. The functions create an image file defined by the parameters. The image is a rectangle of pixels stored from left-to-right, top-to-bottom. Each pixel contains 'comp' channels of data stored interleaved with 8-bits per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. The *data pointer points to the first byte of the top-left-most pixel. For PNG, "stride_in_bytes" is the distance in bytes from the first byte of a row of pixels to the first byte of the next row of pixels. PNG creates output files with the same number of components as the input. The BMP format expands Y to RGB in the file format and does not output alpha. PNG supports writing rectangles of data even when the bytes storing rows of data are not consecutive in memory (e.g. sub-rectangles of a larger image), by supplying the stride between the beginning of adjacent rows. The other formats do not. (Thus you cannot write a native-format BMP through the BMP writer, both because it is in BGR order and because it may have padding at the end of the line.) PNG allows you to set the deflate compression level by setting the global variable 'stbi_write_png_compression_level' (it defaults to 8). HDR expects linear float data. Since the format is always 32-bit rgb(e) data, alpha (if provided) is discarded, and for monochrome data it is replicated across all three channels. TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed data, set the global variable 'stbi_write_tga_with_rle' to 0. JPEG does ignore alpha channels in input data; quality is between 1 and 100. Higher quality looks better but results in a bigger image. JPEG baseline (no JPEG progressive).

Credits section /// /// ## About /// This is a minimal state immediate mode graphical user interface toolkit /// written in ANSI C and licensed under public domain. It was designed as a simple /// embeddable user interface for application and does not have any dependencies, /// a default renderbackend or OS window and input handling but instead provides a very modular /// library approach by using simple input state for input and draw /// commands describing primitive shapes as output. So instead of providing a /// layered library that tries to abstract over a number of platform and /// render backends it only focuses on the actual UI. /// /// ## Highlights /// - Graphical user interface toolkit /// - Single header library /// - Written in C89 (a.k.a. ANSI C or ISO C90) /// - Small codebase (~18kLOC) /// - Focus on portability, efficiency and simplicity /// - No dependencies (not even the standard library if not wanted) /// - Fully skinnable and customizable /// - Low memory footprint with total memory control if needed or wanted /// - UTF-8 support /// - No global or hidden state /// - Customizable library modules (you can compile and use only what you need) /// - Optional font baker and vertex buffer output /// /// ## Features /// - Absolutely no platform dependent code /// - Memory management control ranging from/to /// - Ease of use by allocating everything from standard library /// - Control every byte of memory inside the library /// - Font handling control ranging from/to /// - Use your own font implementation for everything /// - Use this libraries internal font baking and handling API /// - Drawing output control ranging from/to /// - Simple shapes for more high level APIs which already have drawing capabilities /// - Hardware accessible anti-aliased vertex buffer output /// - Customizable colors and properties ranging from/to /// - Simple changes to color by filling a simple color table /// - Complete control with ability to use skinning to decorate widgets /// - Bendable UI library with widget ranging from/to /// - Basic widgets like buttons, checkboxes, slider, ... /// - Advanced widget like abstract comboboxes, contextual menus,... /// - Compile time configuration to only compile what you need /// - Subset which can be used if you do not want to link or use the standard library /// - Can be easily modified to only update on user input instead of frame updates /// /// ## Usage /// This library is self contained in one single header file and can be used either /// in header only mode or in implementation mode. The header only mode is used /// by default when included and allows including this header in other headers /// and does not contain the actual implementation.

/// /// The implementation mode requires to define the preprocessor macro /// NK_IMPLEMENTATION in *one* .c/.cpp file before #including this file, e.g.: /// /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C /// #define NK_IMPLEMENTATION /// #include "nuklear.h" /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /// /// Also optionally define the symbols listed in the section "OPTIONAL DEFINES" /// below in header and implementation mode if you want to use additional functionality /// or need more control over the library. /// /// !!! WARNING /// Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions. /// /// ### Flags /// Flag | Description /// --------------------------------|------------------------------------------ /// NK_PRIVATE | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation /// NK_INCLUDE_FIXED_TYPES | If defined it will include header `` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself. /// NK_INCLUDE_DEFAULT_ALLOCATOR | If defined it will include header `` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management. /// NK_INCLUDE_STANDARD_IO | If defined it will include header `` and provide additional functions depending on file loading. /// NK_INCLUDE_STANDARD_VARARGS | If defined it will include header and provide additional functions depending on file loading. /// NK_INCLUDE_STANDARD_BOOL | If defined it will include header `` for nk_bool otherwise nuklear defines nk_bool as int. /// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,... /// NK_INCLUDE_FONT_BAKING | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it. /// NK_INCLUDE_DEFAULT_FONT | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font /// NK_INCLUDE_COMMAND_USERDATA | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures. /// NK_BUTTON_TRIGGER_ON_RELEASE | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released. /// NK_ZERO_COMMAND_MEMORY | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame. /// NK_UINT_DRAW_INDEX | Defining this will set the size of vertex index elements when using NK_VERTEX_BUFFER_OUTPUT to 32bit instead of the default of 16bit /// NK_KEYSTATE_BASED_INPUT | Define this if your backend uses key state for each frame rather than key press/release events /// /// !!! WARNING /// The following flags will pull in the standard C library: /// - NK_INCLUDE_DEFAULT_ALLOCATOR /// - NK_INCLUDE_STANDARD_IO /// - NK_INCLUDE_STANDARD_VARARGS /// /// !!! WARNING /// The following flags if defined need to be defined for both header and implementation: /// - NK_INCLUDE_FIXED_TYPES /// - NK_INCLUDE_DEFAULT_ALLOCATOR /// - NK_INCLUDE_STANDARD_VARARGS /// - NK_INCLUDE_STANDARD_BOOL /// - NK_INCLUDE_VERTEX_BUFFER_OUTPUT /// - NK_INCLUDE_FONT_BAKING /// - NK_INCLUDE_DEFAULT_FONT /// - NK_INCLUDE_STANDARD_VARARGS /// - NK_INCLUDE_COMMAND_USERDATA /// - NK_UINT_DRAW_INDEX /// /// ### Constants /// Define | Description /// --------------------------------|--------------------------------------- /// NK_BUFFER_DEFAULT_INITIAL_SIZE | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it. /// NK_MAX_NUMBER_BUFFER | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient. /// NK_INPUT_MAX | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient. /// /// !!! WARNING /// The following constants if defined need to be defined for both header and implementation: /// - NK_MAX_NUMBER_BUFFER /// - NK_BUFFER_DEFAULT_INITIAL_SIZE /// - NK_INPUT_MAX /// /// ### Dependencies /// Function | Description /// ------------|--------------------------------------------------------------- /// NK_ASSERT | If you don't define this, nuklear will use with assert(). /// NK_MEMSET | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version. /// NK_MEMCPY | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version. /// NK_INV_SQRT | You can define this to your own inverse sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version. /// NK_SIN | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation. /// NK_COS | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation. /// NK_STRTOD | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!). /// NK_DTOA | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!). /// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe. /// /// !!!

Calling any widgets outside these two functions will result in an /// assert in debug or no state change in release mode.

/// /// Each window holds frame persistent state like position, size, flags, state tables, /// and some garbage collected internal persistent widget state. Each window /// is linked into a window stack list which determines the drawing and overlapping /// order. The topmost window thereby is the currently active window.

/// /// To change window position inside the stack occurs either automatically by /// user input by being clicked on or programmatically by calling `nk_window_focus`. /// Windows by default are visible unless explicitly being defined with flag /// `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag /// `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling /// `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.

/// /// #### Usage /// To create and keep a window you have to call one of the two `nk_begin_xxx` /// functions to start window declarations and `nk_end` at the end.

/* ============================================================================= * * LAYOUT * * ============================================================================= /// ### Layouting /// Layouting in general describes placing widget inside a window with position and size. /// While in this particular implementation there are five different APIs for layouting /// each with different trade offs between control and ease of use.

/// /// All layouting methods in this library are based around the concept of a row. /// A row has a height the window content grows by and a number of columns and each /// layouting method specifies how each widget is placed inside the row. /// After a row has been allocated by calling a layouting functions and then /// filled with widgets will advance an internal pointer over the allocated row.

/// /// To actually define a layout you just call the appropriate layouting function /// and each subsequent widget call will place the widget as specified. Important /// here is that if you define more widgets then columns defined inside the layout /// functions it will allocate the next row without you having to make another layouting

/// call. /// /// Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API /// is that you have to define the row height for each. However the row height /// often depends on the height of the font.

/// /// To fix that internally nuklear uses a minimum row height that is set to the /// height plus padding of currently active font and overwrites the row height /// value if zero.

/// /// If you manually want to change the minimum row height then /// use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to /// reset it back to be derived from font height.

/// /// Also if you change the font in nuklear it will automatically change the minimum /// row height for you and. This means if you change the font but still want /// a minimum row height smaller than the font you have to repush your value.

/// /// For actually more advanced UI I would even recommend using the `nk_layout_space_xxx` /// layouting method in combination with a cassowary constraint solver (there are /// some versions on github with permissive license model) to take over all control over widget /// layouting yourself. However for quick and dirty layouting using all the other layouting /// functions should be fine. /// /// #### Usage /// 1. __nk_layout_row_dynamic__

/// The easiest layouting function is `nk_layout_row_dynamic`. It provides each /// widgets with same horizontal space inside the row and dynamically grows /// if the owning window grows in width. So the number of columns dictates /// the size of each widget dynamically by formula: /// /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c /// widget_width = (window_width - padding - spacing) * (1/colum_count) /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /// /// Just like all other layouting APIs if you define more widget than columns this /// library will allocate a new row and keep all layouting parameters previously /// defined. /// /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c /// if (nk_begin_xxx(...) { /// // first row with height: 30 composed of two widgets /// nk_layout_row_dynamic(&ctx, 30, 2); /// nk_widget(...); /// nk_widget(...); /// // /// // second row with same parameter as defined above /// nk_widget(...); /// nk_widget(...); /// // /// // third row uses 0 for height which will use auto layouting /// nk_layout_row_dynamic(&ctx, 0, 2); /// nk_widget(...); /// nk_widget(...); /// } /// nk_end(...); /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /// /// 2. __nk_layout_row_static__

/// Another easy layouting function is `nk_layout_row_static`. It provides each /// widget with same horizontal pixel width inside the row and does not grow /// if the owning window scales smaller or bigger. /// /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c /// if (nk_begin_xxx(...) { /// // first row with height: 30 composed of two widgets with width: 80 /// nk_layout_row_static(&ctx, 30, 80, 2); /// nk_widget(...); /// nk_widget(...); /// // /// // second row with same parameter as defined above /// nk_widget(...); /// nk_widget(...); /// // /// // third row uses 0 for height which will use auto layouting /// nk_layout_row_static(&ctx, 0, 80, 2); /// nk_widget(...); /// nk_widget(...); /// } /// nk_end(...); /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /// /// 3. __nk_layout_row_xxx__

/// A little bit more advanced layouting API are functions `nk_layout_row_begin`, /// `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly /// specify each column pixel or window ratio in a row. It supports either /// directly setting per column pixel width or widget window ratio but not /// both. Furthermore it is a immediate mode API so each value is directly /// pushed before calling a widget. Therefore the layout is not automatically /// repeating like the last two layouting functions. /// /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c /// if (nk_begin_xxx(...) { /// // first row with height: 25 composed of two widgets with width 60 and 40 /// nk_layout_row_begin(ctx, NK_STATIC, 25, 2); /// nk_layout_row_push(ctx, 60); /// nk_widget(...); /// nk_layout_row_push(ctx, 40); /// nk_widget(...); /// nk_layout_row_end(ctx); /// // /// // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75 /// nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2); /// nk_layout_row_push(ctx, 0.25f); /// nk_widget(...); /// nk_layout_row_push(ctx, 0.75f); /// nk_widget(...); /// nk_layout_row_end(ctx); /// // /// // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75 /// nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2); /// nk_layout_row_push(ctx, 0.25f); /// nk_widget(...); /// nk_layout_row_push(ctx, 0.75f); /// nk_widget(...); /// nk_layout_row_end(ctx); /// } /// nk_end(...); /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /// /// 4. __nk_layout_row__

/// The array counterpart to API nk_layout_row_xxx is the single nk_layout_row /// functions. Instead of pushing either pixel or window ratio for every widget /// it allows to define it by array. The trade of for less control is that /// `nk_layout_row` is automatically repeating. Otherwise the behavior is the /// same. /// /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c /// if (nk_begin_xxx(...) { /// // two rows with height: 30 composed of two widgets with width 60 and 40 /// const float size[] = {60,40}; /// nk_layout_row(ctx, NK_STATIC, 30, 2, ratio); /// nk_widget(...); /// nk_widget(...); /// nk_widget(...); /// nk_widget(...); /// // /// // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75 /// const float ratio[] = {0.25, 0.75}; /// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); /// nk_widget(...); /// nk_widget(...); /// nk_widget(...); /// nk_widget(...); /// // /// // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75 /// const float ratio[] = {0.25, 0.75}; /// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); /// nk_widget(...); /// nk_widget(...); /// nk_widget(...); /// nk_widget(...); /// } /// nk_end(...); /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /// /// 5. __nk_layout_row_template_xxx__

/// The most complex and second most flexible API is a simplified flexbox version without /// line wrapping and weights for dynamic widgets. It is an immediate mode API but /// unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called /// before calling the templated widgets. /// The row template layout has three different per widget size specifier. The first /// one is the `nk_layout_row_template_push_static` with fixed widget pixel width. /// They do not grow if the row grows and will always stay the same. /// The second size specifier is `nk_layout_row_template_push_variable` /// which defines a minimum widget size but it also can grow if more space is available /// not taken by other widgets. /// Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic` /// which are completely flexible and unlike variable widgets can even shrink /// to zero if not enough space is provided. /// /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c /// if (nk_begin_xxx(...) { /// // two rows with height: 30 composed of three widgets /// nk_layout_row_template_begin(ctx, 30); /// nk_layout_row_template_push_dynamic(ctx); /// nk_layout_row_template_push_variable(ctx, 80); /// nk_layout_row_template_push_static(ctx, 80); /// nk_layout_row_template_end(ctx); /// // /// // first row /// nk_widget(...); // dynamic widget can go to zero if not enough space /// nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space /// nk_widget(...); // static widget with fixed 80 pixel width /// // /// // second row same layout /// nk_widget(...); /// nk_widget(...); /// nk_widget(...); /// } /// nk_end(...); /// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /// /// 6. __nk_layout_space_xxx__

/// Finally the most flexible API directly allows you to place widgets inside the /// window. The space layout API is an immediate mode API which does not support /// row auto repeat and directly sets position and size of a widget.

There are three different ways to use the font atlas. The first two will use your font handling scheme and only requires essential data to run nuklear. The next slightly more advanced features is font handling with vertex buffer output. Finally the most complex API wise is using nuklear's font baking API. 1.) Using your own implementation without vertex buffer output -------------------------------------------------------------- So first up the easiest way to do font handling is by just providing a `nk_user_font` struct which only requires the height in pixel of the used font and a callback to calculate the width of a string. This way of handling fonts is best fitted for using the normal draw shape command API where you do all the text drawing yourself and the library does not require any kind of deeper knowledge about which font handling mechanism you use. IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist over the complete life time! I know this sucks but it is currently the only way to switch between fonts. float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) { your_font_type *type = handle.ptr; float text_width = ...; return text_width; } struct nk_user_font font; font.userdata.ptr = &your_font_class_or_struct; font.height = your_font_height; font.width = your_text_width_calculation; struct nk_context ctx; nk_init_default(&ctx, &font); 2.) Using your own implementation with vertex buffer output -------------------------------------------------------------- While the first approach works fine if you don't want to use the optional vertex buffer output it is not enough if you do. To get font handling working for these cases you have to provide two additional parameters inside the `nk_user_font`. First a texture atlas handle used to draw text as subimages of a bigger font atlas texture and a callback to query a character's glyph information (offset, size, ...). So it is still possible to provide your own font and use the vertex buffer output. float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) { your_font_type *type = handle.ptr; float text_width = ...; return text_width; } void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint) { your_font_type *type = handle.ptr; glyph.width = ...; glyph.height = ...; glyph.xadvance = ...; glyph.uv[0].x = ...; glyph.uv[0].y = ...; glyph.uv[1].x = ...; glyph.uv[1].y = ...; glyph.offset.x = ...; glyph.offset.y = ...; } struct nk_user_font font; font.userdata.ptr = &your_font_class_or_struct; font.height = your_font_height; font.width = your_text_width_calculation; font.query = query_your_font_glyph; font.texture.id = your_font_texture; struct nk_context ctx; nk_init_default(&ctx, &font); 3.) Nuklear font baker ------------------------------------ The final approach if you do not have a font handling functionality or don't want to use it in this library is by using the optional font baker. The font baker APIs can be used to create a font plus font atlas texture and can be used with or without the vertex buffer output. It still uses the `nk_user_font` struct and the two different approaches previously stated still work. The font baker is not located inside `nk_context` like all other systems since it can be understood as more of an extension to nuklear and does not really depend on any `nk_context` state. Font baker need to be initialized first by one of the nk_font_atlas_init_xxx functions. If you don't care about memory just call the default version `nk_font_atlas_init_default` which will allocate all memory from the standard library. If you want to control memory allocation but you don't care if the allocated memory is temporary and therefore can be freed directly after the baking process is over or permanent you can call `nk_font_atlas_init`. After successfully initializing the font baker you can add Truetype(.ttf) fonts from different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`. functions. Adding font will permanently store each font, font config and ttf memory block(!) inside the font atlas and allows to reuse the font atlas. If you don't want to reuse the font baker by for example adding additional fonts you can call `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end). As soon as you added all fonts you wanted you can now start the baking process for every selected glyph to image by calling `nk_font_atlas_bake`. The baking process returns image memory, width and height which can be used to either create your own image object or upload it to any graphics library. No matter which case you finally have to call `nk_font_atlas_end` which will free all temporary memory including the font atlas image so make sure you created our texture beforehand. `nk_font_atlas_end` requires a handle to your font texture or object and optionally fills a `struct nk_draw_null_texture` which can be used for the optional vertex output. If you don't want it just set the argument to `NULL`. At this point you are done and if you don't want to reuse the font atlas you can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration memory. Finally if you don't use the font atlas and any of it's fonts anymore you need to call `nk_font_atlas_clear` to free all memory still being used. struct nk_font_atlas atlas; nk_font_atlas_init_default(&atlas); nk_font_atlas_begin(&atlas); nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0); nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0); const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32); nk_font_atlas_end(&atlas, nk_handle_id(texture), 0); struct nk_context ctx; nk_init_default(&ctx, &font->handle); while (1) { } nk_font_atlas_clear(&atlas); The font baker API is probably the most complex API inside this library and I would suggest reading some of my examples `example/` to get a grip on how to use the font atlas. There are a number of details I left out. For example how to merge fonts, configure a font with `nk_font_config` to use other languages, use another texture coordinate format and a lot more: struct nk_font_config cfg = nk_font_config(font_pixel_height); cfg.merge_mode = nk_false or nk_true; cfg.range = nk_font_korean_glyph_ranges(); cfg.coord_type = NK_COORD_PIXEL; nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg);

The buffer's main purpose is to control all memory management inside the GUI toolkit and still leave memory control as much as possible in the hand of the user while also making sure the library is easy to use if not as much control is needed. In general all memory inside this library can be provided from the user in three different ways. The first way and the one providing most control is by just passing a fixed size memory block. In this case all control lies in the hand of the user since he can exactly control where the memory comes from and how much memory the library should consume. Of course using the fixed size API removes the ability to automatically resize a buffer if not enough memory is provided so you have to take over the resizing. While being a fixed sized buffer sounds quite limiting, it is very effective in this library since the actual memory consumption is quite stable and has a fixed upper bound for a lot of cases. If you don't want to think about how much memory the library should allocate at all time or have a very dynamic UI with unpredictable memory consumption habits but still want control over memory allocation you can use the dynamic allocator based API. The allocator consists of two callbacks for allocating and freeing memory and optional userdata so you can plugin your own allocator. The final and easiest way can be used by defining NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory allocation functions malloc and free and takes over complete control over memory in this library. */ struct nk_memory_status { void *memory; unsigned int type; nk_size size; nk_size allocated; nk_size needed; nk_size calls; }; enum nk_allocation_type { NK_BUFFER_FIXED, NK_BUFFER_DYNAMIC }; enum nk_buffer_allocation_type { NK_BUFFER_FRONT, NK_BUFFER_BACK, NK_BUFFER_MAX }; struct nk_buffer_marker { nk_bool active; nk_size offset; }; struct nk_memory {void *ptr;nk_size size;}; struct nk_buffer { struct nk_buffer_marker marker[NK_BUFFER_MAX]; /* buffer marker to free a buffer to a certain offset */ struct nk_allocator pool; /* allocator callback for dynamic buffers */ enum nk_allocation_type type; /* memory management type */ struct nk_memory memory; /* memory and size of the current memory block */ float grow_factor; /* growing factor for dynamic memory management */ nk_size allocated; /* total amount of memory allocated */ nk_size needed; /* totally consumed memory given that enough memory is present */ nk_size calls; /* number of allocation calls */ nk_size size; /* current size of the buffer */ }; #ifdef NK_INCLUDE_DEFAULT_ALLOCATOR NK_API void nk_buffer_init_default(struct nk_buffer*); #endif NK_API void nk_buffer_init(struct nk_buffer*, const struct nk_allocator*, nk_size size); NK_API void nk_buffer_init_fixed(struct nk_buffer*, void *memory, nk_size size); NK_API void nk_buffer_info(struct nk_memory_status*, struct nk_buffer*); NK_API void nk_buffer_push(struct nk_buffer*, enum nk_buffer_allocation_type type, const void *memory, nk_size size, nk_size align); NK_API void nk_buffer_mark(struct nk_buffer*, enum nk_buffer_allocation_type type); NK_API void nk_buffer_reset(struct nk_buffer*, enum nk_buffer_allocation_type type); NK_API void nk_buffer_clear(struct nk_buffer*); NK_API void nk_buffer_free(struct nk_buffer*); NK_API void *nk_buffer_memory(struct nk_buffer*); NK_API const void *nk_buffer_memory_const(const struct nk_buffer*); NK_API nk_size nk_buffer_total(struct nk_buffer*); /* ============================================================== * * STRING * * ===============================================================*/ /* Basic string buffer which is only used in context with the text editor * to manage and manipulate dynamic or fixed size string content.

Instead all drawn shapes, widgets are made of, are buffered into memory and make up a command queue. Each frame therefore fills the command buffer with draw commands that then need to be executed by the user and his own render backend. After that the command buffer needs to be cleared and a new frame can be started. It is probably important to note that the command buffer is the main drawing API and the optional vertex buffer API only takes this format and converts it into a hardware accessible format. To use the command queue to draw your own widgets you can access the command buffer of each window by calling `nk_window_get_canvas` after previously having called `nk_begin`: void draw_red_rectangle_widget(struct nk_context *ctx) { struct nk_command_buffer *canvas; struct nk_input *input = &ctx->input; canvas = nk_window_get_canvas(ctx); struct nk_rect space; enum nk_widget_layout_states state; state = nk_widget(&space, ctx); if (!state) return; if (state != NK_WIDGET_ROM) update_your_widget_by_user_input(...); nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0)); } if (nk_begin(...)) { nk_layout_row_dynamic(ctx, 25, 1); draw_red_rectangle_widget(ctx); } nk_end(..) Important to know if you want to create your own widgets is the `nk_widget` call. It allocates space on the panel reserved for this widget to be used, but also returns the state of the widget space. If your widget is not seen and does not have to be updated it is '0' and you can just return. If it only has to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both update and draw your widget. The reason for separating is to only draw and update what is actually necessary which is crucial for performance. */ enum nk_command_type { NK_COMMAND_NOP, NK_COMMAND_SCISSOR, NK_COMMAND_LINE, NK_COMMAND_CURVE, NK_COMMAND_RECT, NK_COMMAND_RECT_FILLED, NK_COMMAND_RECT_MULTI_COLOR, NK_COMMAND_CIRCLE, NK_COMMAND_CIRCLE_FILLED, NK_COMMAND_ARC, NK_COMMAND_ARC_FILLED, NK_COMMAND_TRIANGLE, NK_COMMAND_TRIANGLE_FILLED, NK_COMMAND_POLYGON, NK_COMMAND_POLYGON_FILLED, NK_COMMAND_POLYLINE, NK_COMMAND_TEXT, NK_COMMAND_IMAGE, NK_COMMAND_IMAGE_FLIPPED, //< @r-lyeh NK_COMMAND_CUSTOM };

Since the actual highly accurate implementations for the standard library functions are quite complex and I do not need high precision for my use cases I use approximations. Sqrt ---- For square root nuklear uses the famous fast inverse square root: https://en.wikipedia.org/wiki/Fast_inverse_square_root with slightly tweaked magic constant. While on today's hardware it is probably not faster it is still fast and accurate enough for nuklear's use cases. IMPORTANT: this requires float format IEEE 754 Sine/Cosine ----------- All constants inside both function are generated Remez's minimax approximations for value range 0...2*PI. The reason why I decided to approximate exactly that range is that nuklear only needs sine and cosine to generate circles which only requires that exact range. In addition I used Remez instead of Taylor for additional precision: www.lolengine.net/blog/2011/12/21/better-function-approximations. The tool I used to generate constants for both sine and cosine (it can actually approximate a lot more functions) can be found here: www.lolengine.net/wiki/oss/lolremez */ #ifndef NK_INV_SQRT #define NK_INV_SQRT nk_inv_sqrt NK_LIB float nk_inv_sqrt(float n) { float x2; const float threehalfs = 1.5f; union {nk_uint i; float f;} conv = {0}; conv.f = n; x2 = n * 0.5f; conv.i = 0x5f375A84 - (conv.i >> 1); conv.f = conv.f * (threehalfs - (x2 * conv.f * conv.f)); return conv.f; } #endif #ifndef NK_SIN #define NK_SIN nk_sin NK_LIB float nk_sin(float x) { NK_STORAGE const float a0 = +1.91059300966915117e-31f; NK_STORAGE const float a1 = +1.00086760103908896f; NK_STORAGE const float a2 = -1.21276126894734565e-2f; NK_STORAGE const float a3 = -1.38078780785773762e-1f; NK_STORAGE const float a4 = -2.67353392911981221e-2f; NK_STORAGE const float a5 = +2.08026600266304389e-2f; NK_STORAGE const float a6 = -3.03996055049204407e-3f; NK_STORAGE const float a7 = +1.38235642404333740e-4f; return a0 + x*(a1 + x*(a2 + x*(a3 + x*(a4 + x*(a5 + x*(a6 + x*a7)))))); } #endif #ifndef NK_COS #define NK_COS nk_cos NK_LIB float nk_cos(float x) { /* New implementation.

Characters extend both above */ /* and below the baseline. */ /* */ /* Current Point */ /* As you draw text to the screen, you keep track of a "current point" */ /* which is the origin of each character. The current point's vertical */ /* position is the baseline. Even "baked fonts" use this model. */ /* */ /* Vertical Font Metrics */ /* The vertical qualities of the font, used to vertically position */ /* and space the characters. See docs for stbtt_GetFontVMetrics. */ /* */ /* Font Size in Pixels or Points */ /* The preferred interface for specifying font sizes in stb_truetype */ /* is to specify how tall the font's vertical extent should be in pixels. */ /* If that sounds good enough, skip the next paragraph. */ /* */ /* Most font APIs instead use "points", which are a common typographic */ /* measurement for describing font size, defined as 72 points per inch. */ /* stb_truetype provides a point API for compatibility. However, true */ /* "per inch" conventions don't make much sense on computer displays */ /* since different monitors have different number of pixels per */ /* inch. For example, Windows traditionally uses a convention that */ /* there are 96 pixels per inch, thus making 'inch' measurements have */ /* nothing to do with inches, and thus effectively defining a point to */ /* be 1.333 pixels. Additionally, the TrueType font data provides */ /* an explicit scale factor to scale a given font's glyphs to points, */ /* but the author has observed that this scale factor is often wrong */ /* for non-commercial fonts, thus making fonts scaled in points */ /* according to the TrueType spec incoherently sized in practice. */ /* */ /* DETAILED USAGE: */ /* */ /* Scale: */ /* Select how high you want the font to be, in points or pixels. */ /* Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute */ /* a scale factor SF that will be used by all other functions. */ /* */ /* Baseline: */ /* You need to select a y-coordinate that is the baseline of where */ /* your text will appear. Call GetFontBoundingBox to get the baseline-relative */ /* bounding box for all characters. SF*-y0 will be the distance in pixels */ /* that the worst-case character could extend above the baseline, so if */ /* you want the top edge of characters to appear at the top of the */ /* screen where y=0, then you would set the baseline to SF*-y0. */ /* */ /* Current point: */ /* Set the current point where the first character will appear. The */ /* first character could extend left of the current point; this is font */ /* dependent. You can either choose a current point that is the leftmost */ /* point and hope, or add some padding, or check the bounding box or */ /* left-side-bearing of the first character to be displayed and set */ /* the current point based on that. */ /* */ /* Displaying a character: */ /* Compute the bounding box of the character.

Just like last the `nk_group` commit the main /// advantage is that you optionally can minimize nuklears runtime /// memory consumption or handle hash collisions. /// - 2016/11/09 (1.26.0) - Added additional `nk_group` version to support external scrollbar /// offset storage. Main advantage is that you can externalize /// the memory management for the offset. It could also be helpful /// if you have a hash collision in `nk_group_begin` but really /// want the name.

In addition to use vsnprintf you have /// to include . So just defining `NK_INCLUDE_STD_VAR_ARGS` /// is not enough. That behavior is now fixed.

This time /// all calculation are correct so no more hackery. /// - 2016/09/13 (1.20.1) - Internal change to divide window/panel flags into panel flags and types. /// Suprisinly spend years in C and still happened to confuse types /// with flags. Probably something to take note. /// - 2016/09/08 (1.20.0) - Added additional helper function to make it easier to just /// take the produced buffers from `nk_convert` and unplug the /// iteration process from `nk_context`. So now you can /// just use the vertex,element and command buffer + two pointer /// inside the command buffer retrieved by calls `nk__draw_begin` /// and `nk__draw_end` and macro `nk_draw_foreach_bounded`. /// - 2016/09/08 (1.19.0) - Added additional asserts to make sure every `nk_xxx_begin` call /// for windows, popups, combobox, menu and contextual is guarded by /// `if` condition and does not produce false drawing output. /// - 2016/09/08 (1.18.0) - Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT` /// to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and /// `NK_SYMBOL_RECT_OUTLINE`. /// - 2016/09/08 (1.17.0) - Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE` /// to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and /// `NK_SYMBOL_CIRCLE_OUTLINE`. /// - 2016/09/08 (1.16.0) - Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES` /// is not defined by supporting the biggest compiler GCC, clang and MSVC. /// - 2016/09/07 (1.15.3) - Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error. /// - 2016/09/04 (1.15.2) - Fixed wrong combobox height calculation. /// - 2016/09/03 (1.15.1) - Fixed gaps inside combo boxes in OpenGL. /// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and /// instead made it user provided. The range of types to convert /// to is quite limited at the moment, but I would be more than /// happy to accept PRs to add additional. /// - 2016/08/30 (1.14.2) - Removed unused variables. /// - 2016/08/30 (1.14.1) - Fixed C++ build errors. /// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly. /// - 2016/08/30 (1.13.4) - Tweaked some default styling variables. /// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would /// refrain from using slider with a big number of steps. /// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the /// window was in Read Only Mode. /// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just /// a hack for combo box and menu. /// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since /// it is bugged and causes issues in window selection. /// - 2016/08/30 (1.12.0) - Removed scaler size.

A window can be hidden/shown /// by using `nk_window_show` and closed by either clicking the close /// icon in a window or by calling `nk_window_close`.

To use it, you just include thread.h to get the API declarations. To get the definitions, you must include thread.h from *one* single C or C++ file, and #define the symbol `THREAD_IMPLEMENTATION` before you do. Customization ------------- thread.h allows for specifying the exact type of 64-bit unsigned integer to be used in its API. By default, it is defined as `unsigned long long`, but as this is not a standard type on all compilers, you can redefine it by #defining THREAD_U64 before including thread.h. This is useful if you, for example, use the types from `` in the rest of your program, and you want thread.h to use compatible types. In this case, you would include thread.h using the following code: #define THREAD_U64 uint64_t #include "thread.h" Note that when customizing this data type, you need to use the same definition in every place where you include thread.h, as it affect the declarations as well as the definitions. thread_current_thread_id ------------------------ thread_id_t thread_current_thread_id( void ) Returns a unique identifier for the calling thread. After the thread terminates, the id might be reused for new threads. thread_yield ------------ void thread_yield( void ) Makes the calling thread yield execution to another thread. The operating system controls which thread is switched to. thread_set_high_priority ------------------------ void thread_set_high_priority( void ) When created, threads are set to run at normal priority. In some rare cases, such as a sound buffer update loop, it can be necessary to have one thread of your application run on a higher priority than the rest. Calling `thread_set_high_priority` will raise the priority of the calling thread, giving it a chance to be run more often. Do not increase the priority of a thread unless you absolutely have to, as it can negatively affect performance if used without care. thread_exit ----------- void thread_exit( int return_code ) Exits the calling thread, as if you had done `return return_code;` from the main body of the thread function. thread_init ------------- thread_ptr_t thread_init( int (*thread_proc)( void* ), void* user_data, char const* name, int stack_size ) Creates a new thread running the `thread_proc` function, passing the `user_data` through to it. The thread will be given the debug name given in the `name` parameter, if supported on the platform, and it will have the stack size specified in the `stack_size` parameter. To get the operating system default stack size, use the defined constant `THREAD_STACK_SIZE_DEFAULT`. When returning from the thread_proc function, the value you return can be received in another thread by calling thread_join. `thread_init` returns a pointer to the thread instance, which can be used as a parameter to the functions `thread_term` and `thread_join`. thread_term -------------- void thread_term( thread_ptr_t thread ) Destroys a thread that was created by calling `thread_init`. Make sure the thread has exited before you attempt to destroy it. This can be accomplished by calling `thread_join`. It is not possible for force termination of a thread by calling `thread_term`. thread_join ----------- int thread_join( thread_ptr_t thread ) Waits for the specified thread to exit. Returns the value which the thread returned when exiting. thread_detach ------------- int thread_detach( thread_ptr_t thread ) Marks the thread as detached. When a detached thread terminates, its resources are automatically released back to the system without the need for another thread to join with the terminated thread. thread_mutex_init ----------------- void thread_mutex_init( thread_mutex_t* mutex ) Initializes the specified mutex instance, preparing it for use. A mutex can be used to lock sections of code, such that it can only be run by one thread at a time. thread_mutex_term ----------------- void thread_mutex_term( thread_mutex_t* mutex ) Terminates the specified mutex instance, releasing any system resources held by it. thread_mutex_lock ----------------- void thread_mutex_lock( thread_mutex_t* mutex ) Takes an exclusive lock on a mutex. If the lock is already taken by another thread, `thread_mutex_lock` will yield the calling thread and wait for the lock to become available before returning. The mutex must be initialized by calling `thread_mutex_init` before it can be locked. thread_mutex_unlock ------------------- void thread_mutex_unlock( thread_mutex_t* mutex ) Releases a lock taken by calling `thread_mutex_lock`. thread_signal_init ------------------ void thread_signal_init( thread_signal_t* signal ) Initializes the specified signal instance, preparing it for use. A signal works like a flag, which can be waited on by one thread, until it is raised from another thread. thread_signal_term ------------------ void thread_signal_term( thread_signal_t* signal ) Terminates the specified signal instance, releasing any system resources held by it. thread_signal_raise ------------------- void thread_signal_raise( thread_signal_t* signal ) Raise the specified signal. Other threads waiting for the signal will proceed. thread_signal_wait ------------------ int thread_signal_wait( thread_signal_t* signal, int timeout_ms ) Waits for a signal to be raised, or until `timeout_ms` milliseconds have passed. If the wait timed out, a value of 0 is returned, otherwise a non-zero value is returned. If the `timeout_ms` parameter is THREAD_SIGNAL_WAIT_INFINITE, `thread_signal_wait` waits indefinitely. thread_atomic_int_load ---------------------- int thread_atomic_int_load( thread_atomic_int_t* atomic ) Returns the value of `atomic` as an atomic operation. thread_atomic_int_store ----------------------- void thread_atomic_int_store( thread_atomic_int_t* atomic, int desired ) Sets the value of `atomic` as an atomic operation. thread_atomic_int_inc --------------------- int thread_atomic_int_inc( thread_atomic_int_t* atomic ) Increments the value of `atomic` by one, as an atomic operation. Returns the value `atomic` had before the operation. thread_atomic_int_dec --------------------- int thread_atomic_int_dec( thread_atomic_int_t* atomic ) Decrements the value of `atomic` by one, as an atomic operation. Returns the value `atomic` had before the operation. thread_atomic_int_add --------------------- int thread_atomic_int_add( thread_atomic_int_t* atomic, int value ) Adds the specified value to `atomic`, as an atomic operation. Returns the value `atomic` had before the operation. thread_atomic_int_sub --------------------- int thread_atomic_int_sub( thread_atomic_int_t* atomic, int value ) Subtracts the specified value to `atomic`, as an atomic operation. Returns the value `atomic` had before the operation. thread_atomic_int_swap ---------------------- int thread_atomic_int_swap( thread_atomic_int_t* atomic, int desired ) Sets the value of `atomic` as an atomic operation. Returns the value `atomic` had before the operation. thread_atomic_int_compare_and_swap ---------------------------------- int thread_atomic_int_compare_and_swap( thread_atomic_int_t* atomic, int expected, int desired ) Compares the value of `atomic` to the value of `expected`, and if they match, sets the vale of `atomic` to `desired`, all as an atomic operation. Returns the value `atomic` had before the operation. thread_atomic_ptr_load ---------------------- void* thread_atomic_ptr_load( thread_atomic_ptr_t* atomic ) Returns the value of `atomic` as an atomic operation. thread_atomic_ptr_store ----------------------- void thread_atomic_ptr_store( thread_atomic_ptr_t* atomic, void* desired ) Sets the value of `atomic` as an atomic operation. thread_atomic_ptr_swap ---------------------- void* thread_atomic_ptr_swap( thread_atomic_ptr_t* atomic, void* desired ) Sets the value of `atomic` as an atomic operation. Returns the value `atomic` had before the operation. thread_atomic_ptr_compare_and_swap ---------------------------------- void* thread_atomic_ptr_compare_and_swap( thread_atomic_ptr_t* atomic, void* expected, void* desired ) Compares the value of `atomic` to the value of `expected`, and if they match, sets the vale of `atomic` to `desired`, all as an atomic operation. Returns the value `atomic` had before the operation. thread_timer_init ----------------- void thread_timer_init( thread_timer_t* timer ) Initializes the specified timer instance, preparing it for use. A timer can be used to sleep a thread for a high precision duration. thread_timer_term ----------------- void thread_timer_term( thread_timer_t* timer ) Terminates the specified timer instance, releasing any system resources held by it. thread_timer_wait ----------------- void thread_timer_wait( thread_timer_t* timer, THREAD_U64 nanoseconds ) Waits until `nanoseconds` amount of time have passed, before returning. thread_tls_create ----------------- thread_tls_t thread_tls_create( void ) Creates a thread local storage (TLS) index. Once created, each thread has its own value for that TLS index, which can be set or retrieved individually. thread_tls_destroy ------------------ void thread_tls_destroy( thread_tls_t tls ) Destroys the specified TLS index. No further calls to `thread_tls_set` or `thread_tls_get` are valid after this. thread_tls_set -------------- void thread_tls_set( thread_tls_t tls, void* value ) Stores a value in the calling thread's slot for the specified TLS index. Each thread has its own value for each TLS index. thread_tls_get -------------- void* thread_tls_get( thread_tls_t tls ) Retrieves the value from the calling thread's slot for the specified TLS index. Each thread has its own value for each TLS index. thread_queue_init ----------------- void thread_queue_init( thread_queue_t* queue, int size, void** values, int count ) Initializes the specified queue instance, preparing it for use. The queue is a lock-free (but not wait-free) single-producer/single-consumer queue - it will not acquire any locks as long as there is space for adding or items to be consume, but will lock and wait when there is not. The `size` parameter specifies the number of elements in the queue. The `values` parameter is an array of queue slots (`size` elements in length), each being of type `void*`. If the queue is initially empty, the `count` parameter should be 0, otherwise it indicates the number of entires, from the start of the `values` array, that the queue is initialized with. The `values` array is not copied, and must remain valid until `thread_queue_term` is called. thread_queue_term ----------------- void thread_queue_term( thread_queue_t* queue ) Terminates the specified queue instance, releasing any system resources held by it. thread_queue_produce -------------------- int thread_queue_produce( thread_queue_t* queue, void* value, int timeout_ms ) Adds an element to a single-producer/single-consumer queue. If there is space in the queue to add another element, no lock will be taken. If the queue is full, calling thread will sleep until an element is consumed from another thread, before adding the element, or until `timeout_ms` milliseconds have passed. If the wait timed out, a value of 0 is returned, otherwise a non-zero value is returned. If the `timeout_ms` parameter is THREAD_QUEUE_WAIT_INFINITE, `thread_queue_produce` waits indefinitely. thread_queue_consume -------------------- void* thread_queue_consume( thread_queue_t* queue, int timeout_ms ) Removes an element from a single-producer/single-consumer queue. If the queue contains at least one element, no lock will be taken. If the queue is empty, the calling thread will sleep until an element is added from another thread, or until `timeout_ms` milliseconds have passed. If the wait timed out, a value of NULL is returned, otherwise `thread_queue_consume` returns the value that was removed from the queue. If the `timeout_ms` parameter is THREAD_QUEUE_WAIT_INFINITE, `thread_queue_consume` waits indefinitely. thread_queue_count ------------------ int thread_queue_count( thread_queue_t* queue ) Returns the number of elements currently held in a single-producer/single-consumer queue. Be aware that by the time you get the count, it might have changed by another thread calling consume or produce, so use with care. **/ /* ---------------------- IMPLEMENTATION ---------------------- */ #ifndef thread_impl #define thread_impl union thread_mutex_t { void* align; char data[ 64 ]; }; union thread_signal_t { void* align; char data[ 116 ]; }; union thread_atomic_int_t { void* align; long i; }; union thread_atomic_ptr_t { void* ptr; }; union thread_timer_t { void* data; char d[ 8 ]; }; #if !THREAD_USE_MCMP struct thread_queue_t { thread_signal_t data_ready; thread_signal_t space_open; thread_atomic_int_t count; thread_atomic_int_t head; thread_atomic_int_t tail; void** values; int size; #ifndef NDEBUG thread_atomic_int_t id_produce_is_set; thread_id_t id_produce; thread_atomic_int_t id_consume_is_set; thread_id_t id_consume; #endif }; #endif #endif /* thread_impl */ #ifdef THREAD_IMPLEMENTATION #undef THREAD_IMPLEMENTATION #if defined( _WIN32 ) #pragma comment( lib, "winmm" ) //< @r-lyeh, tcc support (remove .lib) #define _CRT_NONSTDC_NO_DEPRECATE #define _CRT_SECURE_NO_WARNINGS #if !defined( _WIN32_WINNT ) || _WIN32_WINNT < 0x0501 #undef _WIN32_WINNT #define _WIN32_WINNT 0x501// requires Windows XP minimum #endif #define _WINSOCKAPI_ #pragma warning( push ) #pragma warning( disable: 4668 ) // 'symbol' is not defined as a preprocessor macro, replacing with '0' for 'directives' #pragma warning( disable: 4255 ) #include #pragma warning( pop ) // To set thread name const DWORD MS_VC_EXCEPTION = 0x406D1388; #pragma pack( push, 8 ) typedef struct tagTHREADNAME_INFO { DWORD dwType; LPCSTR szName; DWORD dwThreadID; DWORD dwFlags; } THREADNAME_INFO; #pragma pack(pop) #elif defined( __linux__ ) || defined( __APPLE__ ) || defined( __ANDROID__ ) || defined( __EMSCRIPTEN__ ) //< @r-lyeh, ems #ifndef _GNU_SOURCE #define _GNU_SOURCE //< @r-lyeh: pthread_setname_np() #endif #include #include #include #else #error Unknown platform. #endif #ifndef NDEBUG #include #endif thread_id_t thread_current_thread_id( void ) { #if defined( _WIN32 ) return (void*) (uintptr_t)GetCurrentThreadId(); #elif defined( __linux__ ) || defined( __APPLE__ ) || defined( __ANDROID__ ) || defined( __EMSCRIPTEN__ ) //< @r-lyeh, ems return (void*) pthread_self(); #else #error Unknown platform. #endif } void thread_yield( void ) { #if defined( _WIN32 ) SwitchToThread(); #elif defined( __linux__ ) || defined( __APPLE__ ) || defined( __ANDROID__ ) || defined( __EMSCRIPTEN__ ) //< @r-lyeh, ems sched_yield(); #else #error Unknown platform. #endif } void thread_exit( int return_code ) { #if defined( _WIN32 ) ExitThread( (DWORD) return_code ); #elif defined( __linux__ ) || defined( __APPLE__ ) || defined( __ANDROID__ ) || defined( __EMSCRIPTEN__ ) //< @r-lyeh, ems pthread_exit( (void*)(uintptr_t) return_code ); #else #error Unknown platform. #endif } thread_ptr_t thread_init( int (*thread_proc)( void* ), void* user_data, char const* name, int stack_size ) { #if defined( _WIN32 ) DWORD thread_id; HANDLE handle = CreateThread( NULL, stack_size > 0 ?

A high-level API combines the demuxer, video & audio decoders in an easy to use wrapper. Lower-level APIs for accessing the demuxer, video decoder and audio decoder, as well as providing different data sources are also available. Interfaces are written in an object orientet style, meaning you create object instances via various different constructor functions (plm_*create()), do some work on them and later dispose them via plm_*destroy(). plm_* ......... the high-level interface, combining demuxer and decoders plm_buffer_* .. the data source used by all interfaces plm_demux_* ... the MPEG-PS demuxer plm_video_* ... the MPEG1 Video ("mpeg1") decoder plm_audio_* ... the MPEG1 Audio Layer II ("mp2") decoder With the high-level interface you have two options to decode video & audio: 1. Use plm_decode() and just hand over the delta time since the last call. It will decode everything needed and call your callbacks (specified through plm_set_{video|audio}_decode_callback()) any number of times. 2. Use plm_decode_video() and plm_decode_audio() to decode exactly one frame of video or audio data at a time. How you handle the synchronization of both streams is up to you. If you only want to decode video *or* audio through these functions, you should disable the other stream (plm_set_{video|audio}_enabled(FALSE)) Video data is decoded into a struct with all 3 planes (Y, Cr, Cb) stored in separate buffers. You can either convert this to RGB on the CPU (slow) via the plm_frame_to_rgb() function or do it on the GPU with the following matrix: mat4 bt601 = mat4( 1.16438, 0.00000, 1.59603, -0.87079, 1.16438, -0.39176, -0.81297, 0.52959, 1.16438, 2.01723, 0.00000, -1.08139, 0, 0, 0, 1 ); gl_FragColor = vec4(y, cb, cr, 1.0) * bt601; Audio data is decoded into a struct with either one single float array with the samples for the left and right channel interleaved, or if the PLM_AUDIO_SEPARATE_CHANNELS is defined *before* including this library, into two separate float arrays - one for each channel. Data can be supplied to the high level interface, the demuxer and the decoders in three different ways: 1. Using plm_create_from_filename() or with a file handle with plm_create_from_file(). 2. Using plm_create_with_memory() and supplying a pointer to memory that contains the whole file. 3. Using plm_create_with_buffer(), supplying your own plm_buffer_t instance and periodically writing to this buffer. When using your own plm_buffer_t instance, you can fill this buffer using plm_buffer_write(). You can either monitor plm_buffer_get_remaining() and push data when appropriate, or install a callback on the buffer with plm_buffer_set_load_callback() that gets called whenever the buffer needs more data. A buffer created with plm_buffer_create_with_capacity() is treated as a ring buffer, meaning that data that has already been read, will be discarded. In contrast, a buffer created with plm_buffer_create_for_appending() will keep all data written to it in memory. This enables seeking in the already loaded data. There should be no need to use the lower level plm_demux_*, plm_video_* and plm_audio_* functions, if all you want to do is read/decode an MPEG-PS file. However, if you get raw mpeg1video data or raw mp2 audio data from a different source, these functions can be used to decode the raw data directly. Similarly, if you only want to analyze an MPEG-PS file or extract raw video or audio packets from it, you can use the plm_demux_* functions. This library uses malloc(), realloc() and free() to manage memory. Typically all allocation happens up-front when creating the interface. However, the default buffer size may be too small for certain inputs. In these cases plmpeg will realloc() the buffer with a larger size whenever needed. You can configure the default buffer size by defining PLM_BUFFER_DEFAULT_SIZE *before* including this library. See below for detailed the API documentation. */ #ifndef PL_MPEG_H #define PL_MPEG_H #include #include #ifdef __cplusplus extern "C" { #endif // ----------------------------------------------------------------------------- // Public Data Types // Object types for the various interfaces typedef struct plm_t plm_t; typedef struct plm_buffer_t plm_buffer_t; typedef struct plm_demux_t plm_demux_t; typedef struct plm_video_t plm_video_t; typedef struct plm_audio_t plm_audio_t; // Demuxed MPEG PS packet // The type maps directly to the various MPEG-PES start codes.

It only supports GET and POST https commands, and is designed for when you just need a very basic way of communicating over https. https.h is a single-header library, and does not need any .lib files or other binaries, or any build scripts. To use it, you just include https.h to get the API declarations. To get the definitions, you must include https.h from *one* single C or C++ file, and #define the symbol `HTTPS_IMPLEMENTATION` before you do. Customization ------------- ### Custom memory allocators For working memory and to store the retrieved data, https.h needs to do dynamic allocation by calling `malloc`. Programs might want to keep track of allocations done, or use custom defined pools to allocate memory from. https.h allows for specifying custom memory allocation functions for `malloc` and `free`. This is done with the following code: #define HTTPS_IMPLEMENTATION #define HTTPS_MALLOC( ctx, size ) ( my_custom_malloc( ctx, size ) ) #define HTTPS_FREE( ctx, ptr ) ( my_custom_free( ctx, ptr ) ) #include "https.h" where `my_custom_malloc` and `my_custom_free` are your own memory allocation/deallocation functions. The `ctx` parameter is an optional parameter of type `void*`. When `https_get` or `https_post` is called, , you can pass in a `memctx` parameter, which can be a pointer to anything you like, and which will be passed through as the `ctx` parameter to every `HTTPS_MALLOC`/`HTTPS_FREE` call. For example, if you are doing memory tracking, you can pass a pointer to your tracking data as `memctx`, and in your custom allocation/deallocation function, you can cast the `ctx` param back to the right type, and access the tracking data. If no custom allocator is defined, https.h will default to `malloc` and `free` from the C runtime library. https_get --------- https_t* https_get( char const* url, void* memctx ) Initiates a https GET request with the specified url. `url` is a zero terminated string containing the request location, just like you would type it in a browser, for example `https://www.mattiasgustavsson.com:443/http_test.txt`. `memctx` is a pointer to user defined data which will be passed through to the custom HTTPS_MALLOC/HTTPS_FREE calls. It can be NULL if no user defined data is needed. Returns a `https_t` instance, which needs to be passed to `https_process` to process the request. When the request is finished (or have failed), the returned `https_t` instance needs to be released by calling `https_release`. If the request was invalid, `https_get` returns NULL. https_post ---------- https_t* https_post( char const* url, void const* data, size_t size, void* memctx ) Initiates a https POST request with the specified url. `url` is a zero terminated string containing the request location, just like you would type it in a browser, for example `https://www.mattiasgustavsson.com:443/http_test.txt`. `data` is a pointer to the data to be sent along as part of the request, and `size` is the number of bytes to send. `memctx` is a pointer to user defined data which will be passed through to the custom HTTPS_MALLOC/HTTPS_FREE calls. It can be NULL if no user defined data is needed. Returns a `https_t` instance, which needs to be passed to `https_process` to process the request. When the request is finished (or have failed), the returned `https_t` instance needs to be released by calling `https_release`. If the request was invalid, `https_post` returns NULL. https_process ------------- https_status_t https_process( https_t* https ) https.h uses non-blocking sockets, so after a request have been made by calling either `https_get` or `https_post`, you have to keep calling `https_process` for as long as it returns `HTTPS_STATUS_PENDING`. You can call it from a loop which does other work too, for example from inside a game loop or from a loop which calls `https_process` on multiple requests. If the request fails, `https_process` returns `HTTPS_STATUS_FAILED`, and the fields `status_code` and `reason_phrase` may contain more details (for example, status code can be 404 if the requested resource was not found on the server). If the request completes successfully, it returns `HTTPS_STATUS_COMPLETED`. In this case, the `https_t` instance will contain details about the result. `status_code` and `reason_phrase` contains the details about the result, as specified in the HTTPS protocol. `content_type` contains the MIME type for the returns resource, for example `text/html` for a normal web page. `response_data` is the pointer to the received data, and `resonse_size` is the number of bytes it contains. In the case when the response data is in text format, https.h ensures there is a zero terminator placed immediately after the response data block, so it is safe to interpret the resonse data as a `char*`. Note that the data size in this case will be the length of the data without the additional zero terminator. https_release ------------- void https_release( https_t* https ) Releases the resources acquired by `https_get` or `https_post`. Should be call when you are finished with the request. */ /* ---------------------- IMPLEMENTATION ---------------------- */ #ifdef HTTPS_IMPLEMENTATION #undef HTTPS_IMPLEMENTATION #if defined(_MSC_VER) && _MSC_VER < 1600 typedef __int8 int8_t; typedef unsigned __int8 uint8_t; typedef __int16 int16_t; typedef unsigned __int16 uint16_t; typedef __int32 int32_t; typedef unsigned __int32 uint32_t; typedef __int64 int64_t; typedef unsigned __int64 uint64_t; #else #include #endif #ifdef _WIN32 #undef _CRT_NONSTDC_NO_DEPRECATE #define _CRT_NONSTDC_NO_DEPRECATE #undef _CRT_SECURE_NO_WARNINGS #define _CRT_SECURE_NO_WARNINGS #if !defined( _WIN32_WINNT ) || _WIN32_WINNT < 0x0501 #undef _WIN32_WINNT #define _WIN32_WINNT 0x501// requires Windows XP minimum #endif #pragma warning( push ) #pragma warning( disable: 4619 ) // pragma warning : there is no warning number 'number' #pragma warning( disable: 4127 ) // conditional expression is constant #pragma warning( disable: 4255 ) #pragma warning( disable: 4365 ) // 'action' : conversion from 'type_1' to 'type_2', signed/unsigned mismatch #pragma warning( disable: 4574 ) // 'Identifier' is defined to be '0': did you mean to use '#if identifier'?

It also supports DTLS 1.2 and 1.0. Before using tlse.c you may want to download and compile tomcrypt; alternatively you may use libtomcrypt.c (see Compiling). I'm working at an alternative efficient RSA signing, DH and Curve25519 implementation, to allow the compilation, alternatively, without tomcrypt, on devices where memory and code size is an issue. **Note**: It does not implement 0-RTT. Client-side TLS 1.3 support is experimental. Like this project ? You may donate Bitcoin for this project at 14LqvMzFfaJ82C7wY5iavvTf9HPELYWsax ![](https://raw.githubusercontent.com/eduardsui/edwork/master/bwallet.png) Compiling ---------- Simple TLS client: `$ gcc tlshello.c -o tlshello -ltomcrypt -ltommath -DLTM_DESC` For debuging tls connections, the DEBUG flag must be set (-DDEBUG). Simple TLS server: `$ gcc tlsserverhello.c -o tlsserverhello -ltomcrypt -ltommath -DLTM_DESC` The entire library is a single c file that you just include in your source. The library may also use the libtomcrypt.c amalgamation. In this case, the client may be compiled: `$ gcc tlshello.c -o tlshello -DTLS_AMALGAMATION` and the server: `$ gcc tlsserverhello.c -o tlsserverhello -DTLS_AMALGAMATION` tlse.h is optional (is safe to just include tlse.c). Alternatively, you may include tlse.h and add tlse.c to your makefile (useful when linking against C++). If thread-safety is needed, you need to call `tls_init()` before letting any other threads in, and not use the same object from multiple threads without a mutex. Other than that, TLSe and libtomcrypt are thread-safe. Also, you may want to define LTC_PTHREAD if you're using libtomcrypt. TLSe supports KTLS on linux kernel 4.13 or higher. KTLS is a TLS implementation in the linux kernel. If TLS_RX is not defined, KTLS is send-only (you may use send/sendfile to send data, but you may not use recv). Also, the negotiation must be handled by TLSe. If KTLS support is needed, define WITH_KTLS (compile with -DWITH_KTLS). Note that is not clear which header should be included for linux structure, you may need to check these structures and constants: https://github.com/torvalds/linux/blob/master/Documentation/networking/tls.txt. Usage ---------- You just `#include "tlse.c"` in your code. Everything is a single file. Features ---------- The main feature of this implementation is the ability to serialize TLS context, via tls_export_context and re-import it, via tls_import_context in another pre-forked worker process (socket descriptor may be sent via sendmsg). For now it supports TLS 1.2, TLS 1.1 + 1.0 (when TLS_LEGACY_SUPPORT is defined / default is on), RSA, ECDSA, DHE, ECDHE ciphers: ``TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA256, TLS_DHE_RSA_WITH_AES_256_CBC_SHA256, TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256` and `TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384``. The following ciphers are supported but disabled by default: ``TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_256_GCM_SHA384``. To enable these ciphers, TLSe must be compiled with ``-DNO_TLS_ROBOT_MITIGATION``. ROBOT attack is mitigated by default, but it is recommended to disable RSA encryption to avoid future vulnerabilities. TLSe now supports ChaCha20/Poly1305 ciphers: `TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256`, `TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256` and `TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256`. These ciphers are enabled by default. It has a low level interface, efficient for non-blocking, asynchronous sockets, and a blocking, libssl-style interface. It implements all that is needed for the TLS protocol version 1.2 and a pem/der parser. From tomcrypt it uses RSA, ECDSA and AES(GCM and CBC) encryption/decryption, SHA1, SHA256, SHA384, SHA512 and HMAC functions. Now it supports client certificate. To request a client certificate, call ``tls_request_client_certificate(TLSContext *)`` following ``tls_accept(TLSContext *)``. It implements SNI extension (Server Name Indication). To get the SNI string call ``tls_sni(TLSContext *)``. It also implements SCSV and ALPN (see ``tls_add_alpn(struct TLSContext *, const char *)`` and ``const char *tls_alpn(struct TLSContext *)``. The library supports certificate validation by using ``tls_certificate_chain_is_valid``, ``tls_certificate_chain_is_valid_root``, ``tls_certificate_valid_subject`` and ``tls_certificate_is_valid``(checks not before/not after). Note that certificates fed to ``tls_certificate_chain_is_valid`` must be in correct order (certificate 2 signs certificate 1, certificate 3 signs certificate 2 and so on; also certificate 1 (first) is the certificate to be used in key exchange). This library was written to be used by my other projects [Concept Applications Server](https://github.com/Devronium/ConceptApplicationServer "Concept Application Server") and [Concept Native Client](https://github.com/Devronium/ConceptClientQT "Concept Client QT") Examples ---------- 1. [examples/tlsclienthello.c](https://github.com/eduardsui/tlslayer/blob/master/examples/tlsclienthello.c) simple client example 2. [examples/tlshelloworld.c](https://github.com/eduardsui/tlslayer/blob/master/examples/tlshelloworld.c) simple server example 3. [examples/tlssimple.c](https://github.com/eduardsui/tlslayer/blob/master/examples/tlssimple.c) simple blocking client using libssl-ish API 4. [examples/tlssimpleserver.c](https://github.com/eduardsui/tlslayer/blob/master/examples/tlssimpleserver.c) simple blocking server using libssl-ish API After compiling the examples, in the working directory, you should put fullchain.pem and privkey.pem in a directory called testcert for running the server examples. I've used [letsencrypt](https://github.com/letsencrypt/letsencrypt) for certificate generation (is free!). Important security note ---------- Note that for DTLS, it doesn't implement a state machine, so using this DTLS implementation with UDP (server) may expose your server to DoS attack.

It is already installed on most unix systems. - On osx, the package dialog can be installed via http://macappstore.org/dialog or http://macports.org - On windows, for curses dialogs console mode, dialog.exe should be copied somewhere on your executable path.

Originally written by Jeff Roberts at RAD Game Tools - 2015/10/20. Hereby placed in public domain. This is a full sprintf replacement that supports everything that the C runtime sprintfs support, including float/double, 64-bit integers, hex floats, field parameters (%*.*d stuff), length reads backs, etc. Why would you need this if sprintf already exists? Well, first off, it's *much* faster (see below). It's also much smaller than the CRT versions code-space-wise. We've also added some simple improvements that are super handy (commas in thousands, callbacks at buffer full, for example). Finally, the format strings for MSVC and GCC differ for 64-bit integers (among other small things), so this lets you use the same format strings in cross platform code. It uses the standard single file trick of being both the header file and the source itself. If you just include it normally, you just get the header file function definitions. To get the code, you include it from a C or C++ file and define STB_SPRINTF_IMPLEMENTATION first. It only uses va_args macros from the C runtime to do it's work. It does cast doubles to S64s and shifts and divides U64s, which does drag in CRT code on most platforms. It compiles to roughly 8K with float support, and 4K without. As a comparison, when using MSVC static libs, calling sprintf drags in 16K. API: ==== int stbsp_sprintf( char * buf, char const * fmt, ... ) int stbsp_snprintf( char * buf, int count, char const * fmt, ... ) Convert an arg list into a buffer. stbsp_snprintf always returns a zero-terminated string (unlike regular snprintf). int stbsp_vsprintf( char * buf, char const * fmt, va_list va ) int stbsp_vsnprintf( char * buf, int count, char const * fmt, va_list va ) Convert a va_list arg list into a buffer. stbsp_vsnprintf always returns a zero-terminated string (unlike regular snprintf). int stbsp_vsprintfcb( STBSP_SPRINTFCB * callback, void * user, char * buf, char const * fmt, va_list va ) typedef char * STBSP_SPRINTFCB( char const * buf, void * user, int len ); Convert into a buffer, calling back every STB_SPRINTF_MIN chars. Your callback can then copy the chars out, print them or whatever. This function is actually the workhorse for everything else. The buffer you pass in must hold at least STB_SPRINTF_MIN characters. // you return the next buffer to use or 0 to stop converting void stbsp_set_separators( char comma, char period ) Set the comma and period characters to use. FLOATS/DOUBLES: =============== This code uses a internal float->ascii conversion method that uses doubles with error correction (double-doubles, for ~105 bits of precision). This conversion is round-trip perfect - that is, an atof of the values output here will give you the bit-exact double back. One difference is that our insignificant digits will be different than with MSVC or GCC (but they don't match each other either). We also don't attempt to find the minimum length matching float (pre-MSVC15 doesn't either). If you don't need float or doubles at all, define STB_SPRINTF_NOFLOAT and you'll save 4K of code space. 64-BIT INTS: ============ This library also supports 64-bit integers and you can use MSVC style or GCC style indicators (%I64d or %lld). It supports the C99 specifiers for size_t and ptr_diff_t (%jd %zd) as well. EXTRAS: ======= Like some GCCs, for integers and floats, you can use a ' (single quote) specifier and commas will be inserted on the thousands: "%'d" on 12345 would print 12,345. For integers and floats, you can use a "$" specifier and the number will be converted to float and then divided to get kilo, mega, giga or tera and then printed, so "%$d" 1000 is "1.0 k", "%$.2d" 2536000 is "2.53 M", etc. For byte values, use two $:s, like "%$$d" to turn 2536000 to "2.42 Mi". If you prefer JEDEC suffixes to SI ones, use three $:s: "%$$$d" -> "2.42 M". To remove the space between the number and the suffix, add "_" specifier: "%_$d" -> "2.53M". In addition to octal and hexadecimal conversions, you can print integers in binary: "%b" for 256 would print 100. PERFORMANCE vs MSVC 2008 32-/64-bit (GCC is even slower than MSVC): =================================================================== "%d" across all 32-bit ints (4.8x/4.0x faster than 32-/64-bit MSVC) "%24d" across all 32-bit ints (4.5x/4.2x faster) "%x" across all 32-bit ints (4.5x/3.8x faster) "%08x" across all 32-bit ints (4.3x/3.8x faster) "%f" across e-10 to e+10 floats (7.3x/6.0x faster) "%e" across e-10 to e+10 floats (8.1x/6.0x faster) "%g" across e-10 to e+10 floats (10.0x/7.1x faster) "%f" for values near e-300 (7.9x/6.5x faster) "%f" for values near e+300 (10.0x/9.1x faster) "%e" for values near e-300 (10.1x/7.0x faster) "%e" for values near e+300 (9.2x/6.0x faster) "%.320f" for values near e-300 (12.6x/11.2x faster) "%a" for random values (8.6x/4.3x faster) "%I64d" for 64-bits with 32-bit values (4.8x/3.4x faster) "%I64d" for 64-bits > 32-bit values (4.9x/5.5x faster) "%s%s%s" for 64 char strings (7.1x/7.3x faster) "...512 char string..."

Here is a brief description of each category: // Control Nodes: Control nodes are used to control the flow of the behavior tree. They determine the order in which child nodes are executed and how the results of those nodes are combined. They are usually parent nodes. // Action Nodes: Action nodes are used to perform specific actions or tasks within the behavior tree. They can include actions such as moving, attacking, or interacting with objects in the game world. They are usually leaf nodes. // Decorator Nodes: Decorator nodes are used to modify the behavior of child nodes in some way. They can be used to repeat child nodes, invert the result of a child node, or add a cooldown period between executions. They are usually located between control and action nodes. // --- VARIABLES // Key Prefixes: // {visiblity:(l)ocal,s(q)uad,(r)ace,(f)action,(g)lobal} // [persistence:(t)emp,(u)serdata,(s)avegame,(c)loud] + '_' + name. // [persistence:(tmp),(usr)data,(sav)egame,(net)cloud] + '_' + name. // Ie, l_health = 123.4, gsav_player = "john" // --- ACTION NODES // [ ] * Actions/Behaviors have a common structure: // [ ] - Entry point (function name) for a C call or Lua script. // [ ] * Status: // [ ] - Uninitialized (never run) // [ ] - Running (in progress) // [ ] - Suspended (on hold till resumed) // [ ] - Success (finished and succeeded) // [ ] - Failure (finished and failed) // [ ] * Optional callbacks: // [ ] - on_enter // [ ] - on_leave // [ ] - on_success // [ ] - on_failure // [ ] - on_suspend // [ ] - on_resume // [x] Action Node: This node performs a single action, such as moving to a specific location or attacking a target. // [ ] Blackboard Node: Node that reads and writes data to a shared memory space known as a blackboard. The blackboard can be used to store information that is relevant to multiple nodes in the behavior tree. // [ ] SetKey(keyVar,object) // [ ] HasKey(keyVar) // [ ] CompareKeys(keyVar1, operator < <= > >= == !=, keyVar2) // [ ] SetTags(names=blank,cooldownTime=inf,bIsCooldownAdditive=false) // [ ] HasTags(names=blank,bAllRequired=true) // [ ] PushToStack(keyVar,itemObj): creates a new stack if one doesnt exist, and stores it in the passed variable name, and then pushes item object onto it. // [ ] PopFromStack(keyVar,itemVar): pop pops an item off the stack, and stores it in the itemVar variable, failing if the stack is already empty. // [ ] IsEmptyStack(keyVar): checks if the stack passed is empty and returns success if it is, and failure if its not. // [ ] Communication Node: This is a type of action node that allows an AI agent to communicate with other agents or entities in the game world. The node takes an input specifying the message to be communicated and the recipient(s) of the message (wildmask,l/p/f/g prefixes). The node then sends the message to the designated recipient(s) and returns success when the communication is completed. This node can be useful for implementing behaviors that require the AI agent to coordinate with other agents or to convey information to the player. It could use a radius argument to specify the maximum allowed distance for the recipients. // [ ] Condition Node: A leaf node that checks a specific condition, such as the distance to an object, the presence of an enemy, or the status of a health bar. // [ ] Distance Condition Node: This is a type of condition node that evaluates whether an AI agent is within a specified distance of a target object or location. The node takes two inputs: the current position of the AI agent and the position of the target object or location. If the distance between the two is within a specified range, the node returns success. If the distance is outside of the specified range, the node returns failure. This node can be useful for implementing behaviors that require the AI agent to maintain a certain distance from a target, such as following or avoiding an object. Could use a flag to disambiguate between linear distance and path distance. // [ ] Query Node: This node checks a condition and returns success or failure based on the result. For example, a query node could check whether an enemy is within range or whether a door is locked. // [ ] Query Node: A type of decorator node that retrieves information from a database or external system, such as a web service or file system. The Query node can be used to retrieve data that is not available within the game engine, such as weather or traffic conditions. // [ ] A condition is made of: // [ ] - Optional [!] negate // [ ] - Mandatory Value1(Int/Flt/Bool/VarName/FuncName) // [ ] - Optional operator [< <= > >= == !=] and Value2(Int/Flt/Bool/VarName/FuncName) // [ ] AllConditions(...) : SUCCESS if ( empty array || all conditions met) // [ ] AnyConditions(...) : SUCCESS if (!empty array && one conditions met) // --- DECORATOR NODES // [ ] Cooldown Node: Decorator node that adds a cooldown period between the execution of a child node, preventing it from being executed again until the cooldown period has elapsed. // [x] Counter Node: Decorator node that limits the number of times that a child node can execute. For example, if the child node has executed a certain number of times, the Counter node will return a failure. // [x] Once Node: Decorator node that triggers a specified action when a condition is met for the first time. This can be useful for triggering a one-time event, such as when an AI agent discovers a hidden item or reaches a new area of the game world. // [x] Inverter Node: Decorator node that inverts the result of a child node, returning success if the child node fails and failure if the child node succeeds. This can be useful for negating the outcome of a particular behavior, such as avoiding a certain area of the game world. // [x] Repeater Node: Decorator node that repeats the execution of a child node a specified number of times or indefinitely. // [x] Repeat(times=inf): Runs child node given times. These are often used at the very base of the tree, to make the tree to run continuously. // [ ] RepeatIf(strong/weak condition): Runs child node as long as the conditions are met. // [ ] RepeatIfOk(times=inf): Runs child node if it succeedes, max given times. // [ ] RepeatIfFail(times=inf): Runs child node if it fails, max given times. // [ ] Branch Node: 2 children [0] for true, [1] for false // [ ] Resource Node: Decorator node that manages a shared resource, such as a limited supply of ammunition or a limited amount of processing power. The Resource node The node can be used to decide when to use or conserve the resource. For example, if the AI agent is low on ammunition, the node may decide to switch to a melee weapon or to retreat to a safer location. This node can be useful for implementing behaviors that require the AI agent to make strategic decisions about resource use. // [x] Result Node: Decorator node that tracks the result of a child action node and returns either success or failure depending on the outcome. This can be useful for determining whether an action was successful or not, and then adjusting the AI agent's behavior accordingly. // [x] Succeeder Node: Decorator node that always returns success, regardless of the result of its child node. This can be useful for ensuring that certain behaviors are always executed, regardless of the overall success or failure of the behavior tree. // [x] Success(): FAILURE becomes SUCCESS (TRUE). // [x] Failure(): SUCCESS becomes FAILURE (FALSE). // [ ] Throttle Node: Decorator node that limits the rate at which a child node can execute. For example, a Throttle node might ensure that an AI agent can only fire its weapon, or using a special ability, only a certain number of times per second. // [x] Delay Node: Decorator node that adds a delay to the execution of a child node. The delay might be configured to sleep before the execution, after the execution, or both. // [x] Defer Delay(duration_ss=1): Runs the child node, then sleeps for given seconds. // [ ] Ease(time,name): Clamps child time to [0,1] range, and applies easing function on it. // [ ] Dilate(Mul=1,Add=0): Dilates child time // --- CONTROL NODES // [x] Root Node: The topmost node in a behavior tree that represents the start of the decision-making process. Returns success if any of its child nodes suceedes. // [x] Root-Failure Node: Control node that only returns failure if all of its child nodes fail. This can be useful for ensuring that a behavior tree is not prematurely terminated if one or more child nodes fail. // [ ] Event(name): When name event is raised, it suspends current tree and calls child. "Incoming projectile" -> Evade. Stimulus types: may be disabled by event, or autodisabled. // [ ] Raise(name): Triggers event name. // [ ] Checkpoint Node: Control node that saves a state in memory and then continues the tree execution from that point the next time the tree is executed. It can be useful in situations where the behavior tree needs to be interrupted and resumed later. // [ ] Decision Making Node: Control node that implements a decision-making process for the AI agent. The node takes input specifying the available options for the AI agent and the criteria for evaluating each option. The node then evaluates each option based on the specified criteria and selects the best option. This node can be useful for implementing behaviors that require the AI agent to make strategic decisions, such as choosing a target or selecting a path through the game world. // [ ] Could be extended with GOAP if dynamically inserting the scores on each update then calling a Probability Selector Node (0.2,0.3,0.5) // [ ] https://cdn.cloudflare.steamstatic.com/apps/valve/2012/GDC2012_Ruskin_Elan_DynamicDialog.pdf // [ ] Evaluate Node / Recheck(): // [ ] Actively rechecks all existing sub-conditions on a regular basis after having made decisions about them. // [ ] Use this feature to dynamically check for risks or opportunities in selected parts of the tree. // [ ] For example, interrupting a patrol with a search behavior if a disturbance is reported. // [ ] Interrupt Node: Control node that interrupts the execution of a lower-priority node when a higher-priority node needs to be executed. It can be useful for handling urgent tasks or emergency situations. // [ ] Monitor Node: Control node that continuously monitors a condition and triggers a specified action when the condition is met. For example, a Monitor node might monitor the distance between an AI agent and a target and trigger a "retreat" behavior when the distance falls below a certain threshold. // [ ] Observer Node: Control node that monitors the state of the game world and triggers a specified action when certain conditions are met. For example, an Observer node might trigger a "hide" behavior when an enemy is spotted. // [ ] Parallel Node: Control node that executes multiple child nodes simultaneously. The Parallel node continues to execute even if some of its child nodes fail. // [ ] Parallel All Node(required_successes=100%): Control node that executes multiple child nodes simultaneously. Returns false when first child fails, and aborts any other running tasks. Returns true if all its children succeed. // [ ] Parallel One Node(required_successes=1): Control node that executes multiple child nodes simultaneously. Returns true when first child suceedes, and aborts any other running tasks. Returns false if all its children fail. // [ ] Subsumption Node: Control node that allows multiple behaviors to be executed simultaneously, with higher-priority behaviors taking precedence over lower-priority ones. This can be useful for implementing complex, multi-level behaviors in autonomous systems. // [ ] Semaphore Node: Control node that blocks the execution of its child nodes until a certain condition is met. For example, a Semaphore node might block the execution of a behavior until a certain object is in range or a certain event occurs. // [ ] Semaphore Wait Node: Control node that blocks the execution of its child nodes until a resource becomes available. This can be useful for controlling access to shared resources such as a pathfinding system or a communication channel. // [ ] WaitTags(tags=blank,timeout_ss=inf): Stops execution of child node until the cooldown tag(s) do expire. May return earlier if timed out. // [ ] WaitEvent(name=blank,timeout_ss=inf): Stops execution of child node until event is raised. May return earlier if timed out. // [x] Sequence Node(reversed,iterator(From,To)): Control node that executes a series of child nodes in order. If any of the child nodes fail, the Sequence node stops executing and returns a failure. // [ ] Dynamic Sequence Node: Control node that dynamically changes the order in which its child nodes are executed based on certain conditions. For example, a Dynamic Sequence node might give higher priority to a child node that has recently failed or that is more likely to succeed. // [ ] Reverse(): iterates children in reversed order (Iterator:(-1,0) equivalent) // [ ] Iterator(from,to): allows negative indexing. increments if (abs from < abs to), decrements otherwise // [x] Selector Node: Control node that selects a child node to execute based on a predefined priority or set of conditions. The Selector node stops executing child nodes as soon as one of them succeeds. // [ ] Priority Selector Node: Control node that executes its child nodes in order of priority. If the first child node fails, it moves on to the next child node in the list until a successful node is found. This can be useful for implementing behaviors that require a specific order of execution, such as a patrol route or a search pattern. // [ ] Probability Selector Node: Control node that selects a child node to execute based on a probability distribution. For example, if there are three child nodes with probabilities of 0.2, 0.3, and 0.5, the Probability Selector node will execute the third child node 50% of the time. // [ ] Dynamic Selector Node: Control node that dynamically changes the order in which its child nodes are executed based on certain conditions. For example, a Dynamic Selector node might give higher priority to a child node that has recently succeeded or that is more likely to succeed. // [ ] Dynamic Selector Node: Control node that dynamically changes the order in which child nodes are executed based on certain conditions. For example, it may prioritize certain nodes when health is low, and other nodes when resources are scarce. // [ ] Dynamic Priority Node: Control node that dynamically changes the priority of its child nodes based on certain conditions. For example, if a child node is more likely to result in success, the Dynamic Priority node will give it a higher priority. // [ ] Weighted / Cover Selection Node: This is a type of selector node that evaluates the available cover options in the game world and selects the best cover position for the AI agent. The node takes input specifying the current position of the AI agent and the location of potential cover positions. The node then evaluates the cover positions based on criteria such as distance to enemy positions, line of sight, and available cover points, and selects the best option. This node can be useful for implementing behaviors that require the AI agent to take cover and avoid enemy fire. // [ ] Random Selector Node: Control node that selects a child node to execute at random. This can be useful for introducing variety and unpredictability into the behavior of an AI agent. // [ ] Random Weight / Stochastic Node(0.2,0.3,0.5): Control node that introduces randomness into the decision-making process of an AI agent. For example, a Stochastic node might randomly select a child node to execute, with the probability of each child node being proportional to its likelihood of success. // [ ] Break(bool): breaks parent sequence or selector. may return SUCCESS or FAILURE. // [ ] Hybrid Node: Control node that combines the functionality of multiple control nodes, such as a sequence node and a selector node. It can be useful for creating complex behavior patterns that require multiple control structures. The Hybrid Node has two modes of operation: strict mode and flexible mode. In strict mode, the child nodes are executed in a fixed order, similar to a Sequence Node. If any child node fails, the entire Hybrid Node fails. In flexible mode, the child nodes can be executed in any order, similar to a Selector Node. If any child node succeeds, the entire Hybrid Node succeeds. The Hybrid Node is often used when you need to create complex behavior patterns that require multiple control structures. For example, you might use a Hybrid Node to implement a search behavior where the AI agent first moves in a fixed direction for a certain distance (strict mode), but then switches to a more exploratory mode where it randomly explores nearby areas (flexible mode). // [ ] Subtree Node: Control node that calls another behavior tree as a subroutine. This is useful for breaking down complex behaviors into smaller, more manageable parts. // [ ] Call(name): Calls to the child node with the matching name within behavior tree. Returns FAILURE if name is invalid or if invoked behavior returns FAILURE. // [ ] Return(boolean): Exits current Call. // [ ] AttachTree(Name,bDetachAfterUse=true): Attaches subtree to main tree. When a NPC founds the actor, it attaches the behavior to the tree. Ie, Level specific content: Patrols, Initial setups, Story driven events, etc. Ie, DLCs: Behaviors are added to actors in the DLC level (enticers). // [ ] DetachTree(Name) // [ ] Switch Node: Control node that evaluates a condition and then selects one of several possible child nodes to execute based on the result of the condition. // [ ] Switch(name): Jumps to the child node with the matching name within behavior tree. If name is invalid will defer to Fallback child node. // [ ] Timeout Node: Control node that aborts the execution of its child node after a certain amount of time has elapsed. This can be useful for preventing an AI agent from getting stuck in a loop or waiting indefinitely for a particular event to occur. // [ ] TimeLimit(timeout_ss=inf): Give the child any amount of time to finish before it gets canceled. The timer is reset every time the node gains focus. // [ ] Timer Node: Control node which invokes its child node every XX seconds. The timer can repeat the action any given number of times, or indefinitely. // ## Proposal ----------------------------------------------------------------------------- // BehaviorTrees as case-insensitive INI files.

Builds on the node editor example included in Nuklear v1.00, with the aim of being used as a prototype for implementing a functioning node editor. Features: - Nodes of different types. Currently their implementations are #included in the main file, but they could easily be turned into eg. a plugin system. - Pins/pins of different types -- currently float values and colors. - Adding and removing nodes. - Linking nodes, with validation (one link per input, only link similar pins). - Detaching and moving links. - Evaluation of output values of connected nodes. - Memory management based on fixed size arrays for links and node pointers - Multiple node types - Multiple pin types - Linking between pins of the same type - Detaching and reattaching links - Getting value from linked node if pin is connected Todo: - Complete pin types. - Allow dragging from output to input pin. - Cut link by CTRL+clicking input pin. - Cut link by drawing intersect line on a link. - Group elemnts together with mouse, or LSHIFT+clicking. - Drag groups. - DEL elements. - DEL groups. - CTRL-C/CTRL-V/CTRL-X elements. - CTRL-C/CTRL-V/CTRL-X groups. - CTRL-Z,CTRL-Y. - CTRL-N. - CTRL-L,CTRL-S. - CTRL-F. - CTRL-Wheel Zooming. - Allow to extend node types from Lua. Extra todo: - Execution Flow (see: nk_stroke_triangle, nk_fill_triangle) - Complete missing nodes (see: nk_draw_image, nk_draw_text) - Right-click could visualize node/board diagram as Lua script. - Once that done, copy/pasting scripts should work within editor.
