RELEASE NOTES - v0.12.0
=======================
Version 0.12.0 has breaking API changes including changes to the existing API and the removal of deprecated APIs.
Improved Client-Defined Memory Allocation
-----------------------------------------
The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom
allocation callbacks are specified.
To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this:
void* my_malloc(size_t sz, void* pUserData)
{
return malloc(sz);
}
void* my_realloc(void* p, size_t sz, void* pUserData)
{
return realloc(p, sz);
}
void my_free(void* p, void* pUserData)
{
free(p);
}
...
drflac_allocation_callbacks allocationCallbacks;
allocationCallbacks.pUserData = &myData;
allocationCallbacks.onMalloc = my_malloc;
allocationCallbacks.onRealloc = my_realloc;
allocationCallbacks.onFree = my_free;
drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks);
The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC,
DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions.
Every API that opens a drflac object now takes this extra parameter. These include the following:
drflac_open()
drflac_open_relaxed()
drflac_open_with_metadata()
drflac_open_with_metadata_relaxed()
drflac_open_file()
drflac_open_file_with_metadata()

The function to call when the read position of the client data needs to move.

A pointer to application defined data that will be passed to onRead and onSeek.

Return Value
------------

Remarks
-------
Close the decoder with `drflac_close()`.

Opens a FLAC stream with relaxed validation of the header block.
Parameters
----------
onRead (in)
The function to call when data needs to be read from the client.
onSeek (in)
The function to call when the read position of the client data needs to move.
container (in)
Whether or not the FLAC stream is encapsulated using standard FLAC encapsulation or Ogg encapsulation.
pUserData (in, optional)
A pointer to application defined data that will be passed to onRead and onSeek.
pAllocationCallbacks (in, optional)
A pointer to application defined callbacks for managing memory allocations.
Return Value
------------
A pointer to an object representing the decoder.
Remarks
-------
The same as drflac_open(), except attempts to open the stream even when a header block is not present.
Because the header is not necessarily available, the caller must explicitly define the container (Native or Ogg). Do not set this to `drflac_container_unknown`
as that is for internal use only.
Opening in relaxed mode will continue reading data from onRead until it finds a valid frame. If a frame is never found it will continue forever. To abort,
force your `onRead` callback to return 0, which dr_flac will use as an indicator that the end of the stream was found.

Parameters
----------

case it will use DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE.
Sometimes a FLAC file won't keep track of the total sample count. In this situation the function will continuously
read samples into a dynamically sized buffer on the heap until no samples are left.

...
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.

following options before the miniaudio implementation:
```c
#define MA_NO_WAV
#define MA_NO_MP3
#define MA_NO_FLAC
```
Disabling built-in decoding libraries is useful if you use these libraries independantly of the `ma_decoder` API.
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.
}
...
share/public_html/static/music_inc/src/miniaudio.h view on Meta::CPAN
5. Encoding
===========
The `ma_encoding` API is used for writing audio files. The only supported output format is WAV which is achieved via dr_wav which is amalgamated into the
implementation section of miniaudio. 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_resource_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
}
share/public_html/static/music_inc/src/miniaudio.h view on Meta::CPAN
```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

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.

RELEASE NOTES - VERSION 0.10.x
==============================
Version 0.10 includes major API changes and refactoring, mostly concerned with the data conversion system. Data conversion is performed internally to convert
audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies
to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign.
Changes to Data Conversion
--------------------------
The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other
situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a
pointer to the input data directly rather than dealing with a callback.
The following are the data conversion APIs that have been removed and their replacements:
- ma_format_converter -> ma_convert_pcm_frames_format()
- ma_channel_router -> ma_channel_converter
- ma_src -> ma_resampler
- ma_pcm_converter -> ma_data_converter
The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the
`*_process_pcm_frames()` function as a pointer to a buffer.
The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel
conversion is also simple which you can do with `ma_channel_converter` via `ma_channel_converter_process_pcm_frames()`.
Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you
call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to
output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated.
The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably
share/public_html/static/music_inc/src/miniaudio.h view on Meta::CPAN
`lpfOrder` option, which has a maximum value of MA_MAX_FILTER_ORDER.
- Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before
processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however
`ma_data_converter` will handle this for you.
Custom Memory Allocators
------------------------
miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more
flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the
`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure.
The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by
`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same
way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults.
The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults.
Otherwise they will use the relevant callback in the structure.
- ma_malloc()
- ma_realloc()
- ma_free()
- ma_aligned_malloc()
- ma_aligned_free()
- ma_rb_init() / ma_rb_init_ex()
- ma_pcm_rb_init() / ma_pcm_rb_init_ex()
Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom
allocation callbacks.
Buffer and Period Configuration Changes
---------------------------------------
The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables
`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by
the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine
latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called
`periodSizeInFrames` and `periodSizeInMilliseconds`.

with at the same time as the full-duplex changes. I'm hoping this will be the last of the major API changes. Fingers crossed!
The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's your preference.
Full-Duplex Support
-------------------
The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes.
1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted to avoid a third callback just
for full-duplex so the decision was made to break this API and unify the callbacks. Now, there is just one callback which is the same for all three modes
(playback, capture, duplex). The new callback looks like the following:
void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In playback-only mode, pInput will be
null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer returned from the callback since it's not necessary for miniaudio
anymore.
2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client to choose a different PCM format
for the playback and capture sides. The old ma_device_config object simply did not allow this and needed to change. With these changes you now specify the

- Fix a bug where opening a file would return a success code when in fact it failed.
- Fix compilation errors with Visual Studio 6 and 2003.
- Fix warnings on macOS.
v0.10.0 - 2020-03-07
- API CHANGE: Refactor data conversion APIs
- ma_format_converter has been removed. Use ma_convert_pcm_frames_format() instead.
- ma_channel_router has been replaced with ma_channel_converter.
- ma_src has been replaced with ma_resampler
- ma_pcm_converter has been replaced with ma_data_converter
- API CHANGE: Add support for custom memory allocation callbacks. The following APIs have been updated to take an extra parameter for the allocation
callbacks:
- ma_malloc()
- ma_realloc()
- ma_free()
- ma_aligned_malloc()
- ma_aligned_free()
- ma_rb_init() / ma_rb_init_ex()
- ma_pcm_rb_init() / ma_pcm_rb_init_ex()
- API CHANGE: Simplify latency specification in device configurations. The bufferSizeInFrames and bufferSizeInMilliseconds parameters have been replaced with
periodSizeInFrames and periodSizeInMilliseconds respectively. The previous variables defined the size of the entire buffer, whereas the new ones define the
size of a period. The following APIs have been removed since they are no longer relevant:

- Fix some warnings when compiling with Visual C++.
v0.6a - 2018-01-26
- Fix errors with channel mixing when increasing the channel count.
- Improvements to the build system for the OpenAL backend.
- Documentation fixes.
v0.6 - 2017-12-08
- API CHANGE: Expose and improve mutex APIs. If you were using the mutex APIs before this version you'll
need to update.
- API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively.
- API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent.
- Add support for SDL and Emscripten.
- Simplify the build system further for when development packages for various backends are not installed.
With this change, when the compiler supports __has_include, backends without the relevant development
packages installed will be ignored. This fixes the build for old versions of MinGW.
- Fixes to the Android build.
- Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of
audio data to a different format.
- Improvements to f32 -> u8/s16/s24/s32 conversion routines.
- Fix a bug where the wrong value is returned from mal_device_start() for the OpenSL backend.

RELEASE NOTES - v0.12.0
=======================
Version 0.12.0 has breaking API changes including changes to the existing API and the removal of deprecated APIs.
Improved Client-Defined Memory Allocation
-----------------------------------------
The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom
allocation callbacks are specified.
To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this:
void* my_malloc(size_t sz, void* pUserData)
{
return malloc(sz);
}
void* my_realloc(void* p, size_t sz, void* pUserData)
{
return realloc(p, sz);
}
void my_free(void* p, void* pUserData)
{
free(p);
}
...
drflac_allocation_callbacks allocationCallbacks;
allocationCallbacks.pUserData = &myData;
allocationCallbacks.onMalloc = my_malloc;
allocationCallbacks.onRealloc = my_realloc;
allocationCallbacks.onFree = my_free;
drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks);
The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC,
DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions.
Every API that opens a drflac object now takes this extra parameter. These include the following:
drflac_open()
drflac_open_relaxed()
drflac_open_with_metadata()
drflac_open_with_metadata_relaxed()
drflac_open_file()
drflac_open_file_with_metadata()

Parameters
----------
onRead (in)
The function to call when data needs to be read from the client.
onSeek (in)
The function to call when the read position of the client data needs to move.
container (in)
Whether or not the FLAC stream is encapsulated using standard FLAC encapsulation or Ogg encapsulation.

Return Value
------------
A pointer to an object representing the decoder.
Remarks
-------
The same as drflac_open(), except attempts to open the stream even when a header block is not present.
Because the header is not necessarily available, the caller must explicitly define the container (Native or Ogg). Do not set this to `drflac_container_unknown`
as that is for internal use only.
Opening in relaxed mode will continue reading data from onRead until it finds a valid frame. If a frame is never found it will continue forever. To abort,
force your `onRead` callback to return 0, which dr_flac will use as an indicator that the end of the stream was found.

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.
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
```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.
}
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
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)
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
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
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
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()
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
```c
#define MA_NO_WAV
#define MA_NO_MP3
#define MA_NO_FLAC
```
Disabling built-in decoding libraries is useful if you use these libraries independantly of the
`ma_decoder` API.
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.
}
...
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
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 implemen 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 abitrary 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.
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
===========
The `ma_encoding` API is used for writing audio files. The only supported output format is WAV
which is achieved via dr_wav which is amalgamated into the implementation section of miniaudio.
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
}
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
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

ma_resampler_get_expected_output_frame_count() to know how many output frames will be processed for a given number of input frames.

These are the callbacks required to be implemented for a backend. 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.
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
`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_data_format`
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
encounted. 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.

| 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
share/public_html/static/music_worklet_inprogress/decoder/deps/miniaudio/miniaudio.h view on Meta::CPAN
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 procesing 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.

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
