```c
ma_result result;
ma_uint64 framesRead;
result = ma_data_source_read_pcm_frames(pDataSource, pFramesOut, frameCount, &framesRead, loop);
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, loop);
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.
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, MA_FALSE);
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 the `loop` parameter is set to false in the example above. When this is set to true, 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. Instead, initialize multiple data sources for each
instance. This can be extremely inefficient depending on the data source and can result in
glitching due to subtle changes to the state of internal filters.
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 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.
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
```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(&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(&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()`. The engine's global time is incremented automatically as
audio data is read, but it can be reset with `ma_engine_set_time()` 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.
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 in 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

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 varient 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
