-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
-makes it the best option if you need to do data conversion.
-
-In addition to changes to the API design, a few other changes have been made to the data conversion pipeline:
-
- - The sinc resampler has been removed. This was completely broken and never actually worked properly.
- - The linear resampler now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with the
- `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`.
-
-These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is
-that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to
-configure latency.
-
-The following unused APIs have been removed:
-
- ma_get_default_buffer_size_in_milliseconds()
- ma_get_default_buffer_size_in_frames()
-
-The following macros have been removed:
-
- MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY
- MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE
-
-
-Other API Changes
------------------
-Other less major API changes have also been made in version 0.10.
-
-`ma_device_set_stop_callback()` has been removed. If you require a stop callback, you must now set it via the device config just like the data callback.
-
-The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including
-sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes a configuration
-object called `ma_waveform_config` which defines the properties of the waveform. Use `ma_waveform_config_init()` to initialize a `ma_waveform_config` object.
-Use `ma_waveform_read_pcm_frames()` in place of `ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`.
-
-`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies
-the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to
-take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it more flexible, to
-prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added.
-
-`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API.
-
-
-Filters
--------
-The following filters have been added:
-
- |-------------|-------------------------------------------------------------------|
- | API | Description |
- |-------------|-------------------------------------------------------------------|
- | ma_biquad | Biquad filter (transposed direct form 2) |
- | ma_lpf1 | First order low-pass filter |
- | ma_lpf2 | Second order low-pass filter |
- | ma_lpf | High order low-pass filter (Butterworth) |
- | ma_hpf1 | First order high-pass filter |
- | ma_hpf2 | Second order high-pass filter |
- | ma_hpf | High order high-pass filter (Butterworth) |
- | ma_bpf2 | Second order band-pass filter |
- | ma_bpf | High order band-pass filter |
- | ma_peak2 | Second order peaking filter |
- | ma_notch2 | Second order notching filter |
- | ma_loshelf2 | Second order low shelf filter |
- | ma_hishelf2 | Second order high shelf filter |
- |-------------|-------------------------------------------------------------------|
-
-These filters all support 32-bit floating point and 16-bit signed integer formats natively. Other formats need to be converted beforehand.
-
-
-Sine, Square, Triangle and Sawtooth Waveforms
----------------------------------------------
-Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old
-`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_config_init()` to initialize a config object, and then pass it
-into `ma_waveform_init()`. Then use `ma_waveform_read_pcm_frames()` to read PCM data.
-
-
-Noise Generation
-----------------
-A noise generation API has been added. This is used via the `ma_noise` API. Currently white, pink and Brownian noise is supported. The `ma_noise` API is
-similar to the waveform API. Use `ma_noise_config_init()` to initialize a config object, and then pass it into `ma_noise_init()` to initialize a `ma_noise`
-object. Then use `ma_noise_read_pcm_frames()` to read PCM data.
-
-
-Miscellaneous Changes
----------------------
-The MA_NO_STDIO option has been removed. This would disable file I/O APIs, however this has proven to be too hard to maintain for it's perceived value and was
-therefore removed.
-
-Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report.
-
-The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on
-the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it
-was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work,
-this has been removed from all structures.
-
-Results codes have been overhauled. Unnecessary result codes have been removed, and some have been renumbered for organisation purposes. If you are are binding
-maintainer you will need to update your result codes. Support has also been added for retrieving a human readable description of a given result code via the
-`ma_result_description()` API.
-
-ALSA: The automatic format conversion, channel conversion and resampling performed by ALSA is now disabled by default as they were causing some compatibility
-issues with certain devices and configurations. These can be individually enabled via the device config:
-
- ```c
- deviceConfig.alsa.noAutoFormat = MA_TRUE;
- deviceConfig.alsa.noAutoChannels = MA_TRUE;
- deviceConfig.alsa.noAutoResample = MA_TRUE;
- ```

-Definitions
-===========
+3. 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.
-Sample
-------
+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.
-Frame / PCM Frame
------------------
+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".
-Channel
--------
+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.
-Sample Rate
------------
+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.
-Formats
--------
+3.5. Formats
+------------
Throughout miniaudio you will see references to different sample formats:
- |---------------|----------------------------------------|---------------------------|
+ +---------------+----------------------------------------+---------------------------+
| Symbol | Description | Range |

+ +---------------+----------------------------------------+---------------------------+

| ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] |
| ma_format_u8 | 8-bit unsigned integer | [0, 255] |

-Decoding
-========
-The `ma_decoder` API is used for reading audio files. To enable a decoder you must #include the header of the relevant backend library before the

+
+ // The stb_vorbis implementation must come after the implementation of miniaudio.

+ #include "extras/stb_vorbis.c"
```
+A copy of stb_vorbis is included in the "extras" folder in the miniaudio repository (https://github.com/mackron/miniaudio).

+Built-in decoders are amalgamated into the implementation section of miniaudio. You can disable the built-in decoders by specifying one or more of the

+channel counts (with channel mapping) and sample rates.
-Sample Format Conversion
-========================
+
+6.1. 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.

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:

-Ring Buffers
-============
+9. 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()`.
+

+
+10. 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`.

+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

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.

+Logging Levels
+==============
+A log level will automatically include the lower levels. For example, verbose logging will enable everything. The warning log level will only include warnings
+and errors, but will ignore informational and verbose logging. If you only want to handle a specific log level, implement a custom log callback (see
+ma_context_init() for details) and interrogate the `logLevel` parameter.
+
+By default the log level will be set to MA_LOG_LEVEL_ERROR, but you can change this by defining MA_LOG_LEVEL before the implementation of miniaudio.
+
+MA_LOG_LEVEL_VERBOSE
+ Mainly intended for debugging. This will enable all log levels and can be triggered from within the data callback so care must be taken when enabling this
+ in production environments.
+
+MA_LOG_LEVEL_INFO
+ Informational logging. Useful for debugging. This will also enable warning and error logs. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_WARNING
+ Warnings. You should enable this in you development builds and action them when encounted. This will also enable error logs. These logs usually indicate a
+ potential problem or misconfiguration, but still allow you to keep running. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_ERROR
+ Error logging. This will be fired when an operation fails and is subsequently aborted. This can be fired from within the data callback, in which case the
+ device will be stopped. You should always have this log level enabled.

+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 return 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_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_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 `onDeviceWorkerThread()` 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_STATE_STARTED` and no errors have been
+encounted. Do not start or stop the device here. That will be handled from outside the `onDeviceAudioThread()` callback.
+
+The invocation of the `onDeviceAudioThread()` 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_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 `onDeviceAudioThread()` callback,
+look at `ma_device_audio_thread__default_read_write()`.

+
+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

This can be reviewed as compatibility issues arise. The preference is to use _wfopen_s() and _wfopen() as opposed to the wcsrtombs()
fallback, so if you notice your compiler not detecting this properly I'm happy to look at adding support.

It appears there's either a bug in ALSA, a bug in some drivers, or I'm doing something silly; but having resampling enabled causes
problems with some device configurations when used in conjunction with MMAP access mode. To fix this problem we need to disable
resampling.
-

To reproduce this problem, open the "plug:dmix" device, and set the sample rate to 44100. Internally, it looks like dmix uses a
sample rate of 48000. The hardware parameters will get set correctly with no errors, but it looks like the 44100 -> 48000 resampling
doesn't work properly - but only with MMAP access mode. 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.

-It is assumed pulseaudio.h is available when compile-time linking is being used. We use this for type safety when using
-compile time linking (we don't have this luxury when using runtime linking without headers).
+The PulseAudio API, along with Apple's Core Audio, is the worst of the maintream audio APIs. 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.
-When using compile time linking, each of our ma_* equivalents should use the sames types as defined by the header. The
-reason for this is that it allow us to take advantage of proper type safety.
+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.
+
+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_STATE_STARTING` or `MA_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.

+ Technical Note TN2091: Device input using the HAL Output Audio Unit
+ https://developer.apple.com/library/archive/technotes/tn2091/_index.html
+
+ This documentation says the following:
+
+ The internal AudioConverter can handle any *simple* conversion. 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.

Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
the following output configuration:
-
+
- front/left
- side/left
- back/left
-
+
The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. 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.

-MAJOR CHANGES IN VERSION 0.9
-============================
-Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into
-detail about the major changes I would like to apologize. I know it's annoying dealing with breaking API changes, but I think
-it's best to get these changes out of the way now while the library is still relatively young and unknown.
+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.
-There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in
-advance for this. You may want to hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for
-you, and you don't need full-duplex support, you can avoid upgrading (though you won't be getting future bug fixes).
+
+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
+makes it the best option if you need to do data conversion.
+
+In addition to changes to the API design, a few other changes have been made to the data conversion pipeline:
+
+ - The sinc resampler has been removed. This was completely broken and never actually worked properly.
+ - The linear resampler now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with the
+ `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`.
+
+These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is
+that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to
+configure latency.
+
+The following unused APIs have been removed:
+
+ ma_get_default_buffer_size_in_milliseconds()
+ ma_get_default_buffer_size_in_frames()
+
+The following macros have been removed:
+
+ MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY
+ MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE
+
+
+Other API Changes
+-----------------
+Other less major API changes have also been made in version 0.10.
+
+`ma_device_set_stop_callback()` has been removed. If you require a stop callback, you must now set it via the device config just like the data callback.
+
+The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including
+sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes a configuration
+object called `ma_waveform_config` which defines the properties of the waveform. Use `ma_waveform_config_init()` to initialize a `ma_waveform_config` object.
+Use `ma_waveform_read_pcm_frames()` in place of `ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`.
+
+`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies
+the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to
+take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it more flexible, to
+prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added.
+
+`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API.
+
+
+Filters
+-------
+The following filters have been added:
+
+ |-------------|-------------------------------------------------------------------|
+ | API | Description |
+ |-------------|-------------------------------------------------------------------|
+ | ma_biquad | Biquad filter (transposed direct form 2) |
+ | ma_lpf1 | First order low-pass filter |
+ | ma_lpf2 | Second order low-pass filter |
+ | ma_lpf | High order low-pass filter (Butterworth) |
+ | ma_hpf1 | First order high-pass filter |
+ | ma_hpf2 | Second order high-pass filter |
+ | ma_hpf | High order high-pass filter (Butterworth) |
+ | ma_bpf2 | Second order band-pass filter |
+ | ma_bpf | High order band-pass filter |
+ | ma_peak2 | Second order peaking filter |
+ | ma_notch2 | Second order notching filter |
+ | ma_loshelf2 | Second order low shelf filter |
+ | ma_hishelf2 | Second order high shelf filter |
+ |-------------|-------------------------------------------------------------------|
+
+These filters all support 32-bit floating point and 16-bit signed integer formats natively. Other formats need to be converted beforehand.
+
+
+Sine, Square, Triangle and Sawtooth Waveforms
+---------------------------------------------
+Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old
+`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_config_init()` to initialize a config object, and then pass it
+into `ma_waveform_init()`. Then use `ma_waveform_read_pcm_frames()` to read PCM data.
+
+
+Noise Generation
+----------------
+A noise generation API has been added. This is used via the `ma_noise` API. Currently white, pink and Brownian noise is supported. The `ma_noise` API is
+similar to the waveform API. Use `ma_noise_config_init()` to initialize a config object, and then pass it into `ma_noise_init()` to initialize a `ma_noise`
+object. Then use `ma_noise_read_pcm_frames()` to read PCM data.
+
+
+Miscellaneous Changes
+---------------------
+The MA_NO_STDIO option has been removed. This would disable file I/O APIs, however this has proven to be too hard to maintain for it's perceived value and was
+therefore removed.
+
+Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report.
+
+The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on
+the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it
+was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work,
+this has been removed from all structures.
+
+Results codes have been overhauled. Unnecessary result codes have been removed, and some have been renumbered for organisation purposes. If you are are binding
+maintainer you will need to update your result codes. Support has also been added for retrieving a human readable description of a given result code via the
+`ma_result_description()` API.
+
+ALSA: The automatic format conversion, channel conversion and resampling performed by ALSA is now disabled by default as they were causing some compatibility
+issues with certain devices and configurations. These can be individually enabled via the device config:
+
+ ```c
+ deviceConfig.alsa.noAutoFormat = MA_TRUE;
+ deviceConfig.alsa.noAutoChannels = MA_TRUE;
+ deviceConfig.alsa.noAutoResample = MA_TRUE;
+ ```

+RELEASE NOTES - VERSION 0.9.x
+=============================
+Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into detail about the major changes I
+would like to apologize. I know it's annoying dealing with breaking API changes, but I think it's best to get these changes out of the way now while the
+library is still relatively young and unknown.
+
+There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in advance for this. You may want to
+hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for you, and you don't need full-duplex support, you can avoid upgrading
+(though you won't be getting future bug fixes).

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:

+ 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.

+ 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 device ID, format, channels, channel map and share mode
- on a per-playback and per-capture basis (see example below). The sample rate must be the same for playback and capture.

- Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now,
- the device ID, device type and callback user data are set in the config. ma_device_init() is now simplified down to taking
- just the context, device config and a pointer to the device object being initialized. The rationale for this change is that
- it just makes more sense to me that these are set as part of the config like everything else.

+ with the following options:
+ - MA_NO_WAV
+ - MA_NO_FLAC
+ - MA_NO_MP3
+ If you get errors about multiple definitions you need to either enable the options above, move the implementation of dr_wav, dr_flac and/or dr_mp3 to before
+ the implementation of miniaudio, or update dr_wav, dr_flac and/or dr_mp3.
+ - Changes to the internal atomics library. This has been replaced with c89atomic.h which is embedded within this file.
+ - Fix a bug when a decoding backend reports configurations outside the limits of miniaudio's decoder abstraction.
+ - Fix the UWP build.
+ - Fix the Core Audio build.
+ - Fix the -std=c89 build on GCC.
+
+v0.10.8 - 2020-06-22
+ - Remove dependency on ma_context from mutexes.
+ - Change ma_data_source_read_pcm_frames() to return a result code and output the frames read as an output parameter.
+ - Change ma_data_source_seek_pcm_frames() to return a result code and output the frames seeked as an output parameter.
+ - Change ma_audio_buffer_unmap() to return MA_AT_END when the end has been reached. This should be considered successful.
+ - Change playback.pDeviceID and capture.pDeviceID to constant pointers in ma_device_config.
+ - Add support for initializing decoders from a virtual file system object. This is achieved via the ma_vfs API and allows the application to customize file
+ IO for the loading and reading of raw audio data. Passing in NULL for the VFS will use defaults. New APIs:
+ - ma_decoder_init_vfs()
+ - ma_decoder_init_vfs_wav()

+ - Add support for memory mapping to ma_data_source.
+ - ma_data_source_map()
+ - ma_data_source_unmap()
+ - Add ma_offset_pcm_frames_ptr() and ma_offset_pcm_frames_const_ptr() which can be used for offsetting a pointer by a specified number of PCM frames.
+ - Add initial implementation of ma_yield() which is useful for spin locks which will be used in some upcoming work.
+ - Add documentation for log levels.
+ - The ma_event API has been made public in preparation for some uncoming work.
+ - Fix a bug in ma_decoder_seek_to_pcm_frame() where the internal sample rate is not being taken into account for determining the seek location.

+ - Fix compilation errors with MA_NO_DEVICE_IO.
+ - Fix some warnings with GCC and -std=c89.
+ - Fix some formatting warnings with GCC and -Wall and -Wpedantic.
