v0.11.4 - 2022-01-12
- AAudio: Add initial support for automatic stream routing.
- Add support for initializing an encoder from a VFS.
- Fix a bug when initializing an encoder from a file where the file handle does not get closed in
the event of an error.
v0.11.3 - 2022-01-07
- Add a new flag for nodes called MA_NODE_FLAG_SILENT_OUTPUT which tells miniaudio that the
output of the node should always be treated as silence. This gives miniaudio an optimization
opportunity by skipping mixing of those nodes. Useful for special nodes that need to have
their outputs wired up to the graph so they're processed, but don't want the output to
contribute to the final mix.
- Add support for fixed sized callbacks. With this change, the data callback will be fired with
a consistent frame count based on the periodSizeInFrames or periodSizeInMilliseconds config
variable (depending on which one is used). If the period size is not specified, the backend's
internal period size will be used. Under the hood this uses an intermediary buffer which
introduces a small inefficiency. To avoid this you can use the `noFixedSizedCallback` config
variable and set it to true. This will make the callback equivalent to the way it was before
this change and will avoid the intermediary buffer, but the data callback could get fired with
an inconsistent frame count which might cause problems where certain operations need to operate
on fixed sized chunks.
- Change the logging system to always process debug log messages. This is useful for allowing
debug and test builds of applications to output debug information that can later be passed on
for debugging in miniaudio. To filter out these messages, just filter against the log level
which will be MA_LOG_LEVEL_DEBUG.
- Change the wav decoder to pick the closest format to the source file by default if no preferred
format is specified.
- Fix a bug where ma_device_get_info() and ma_device_get_name() return an error.
- Fix a bug where ma_data_source_read_pcm_frames() can return MA_AT_END even when some data has
been read. MA_AT_END should only be returned when nothing has been read.
- PulseAudio: Fix some bugs where starting and stopping a device can result in a deadlock.
v0.11.2 - 2021-12-31
- Add a new device notification system to replace the stop callback. The stop callback is still
in place, but will be removed in version 0.12. New code should use the notificationCallback
member in the device config instead of stopCallback.
- Fix a bug where the stopped notification doesn't get fired.
- iOS: The IO buffer size is now configured based on the device's configured period size.
- WebAudio: Optimizations to some JavaScript code.
v0.11.1 - 2021-12-27
- Result codes are now declared as an enum rather than #defines.
- Channel positions (MA_CHANNEL_*) are now declared as an enum rather than #defines.
- Add ma_device_get_info() for retrieving device information from an initialized device.
- Add ma_device_get_name() for retrieving the name of an initialized device.
- Add support for setting the directional attenuation factor to sounds and groups.
- Fix a crash when passing in NULL for the pEngine parameter of ma_engine_init().
- Fix a bug where the node graph will output silence if a node has zero input connections.
- Fix a bug in the engine where sounds in front of the listener are too loud.
- AAudio: Fix an incorrect assert.
- AAudio: Fix a bug that resulted in exclusive mode always resulting in initialization failure.
- AAudio: Fix a bug that resulted in a capture device incorrectly being detected as disconnected.
- OpenSL: Fix an error when initializing a device with a non-NULL device ID.
- OpenSL: Fix some bugs with device initialization.
v0.11.0 - 2021-12-18
- Add a node graph system for advanced mixing and effect processing.
- Add a resource manager for loading and streaming sounds.
- Add a high level engine API for sound management and mixing. This wraps around the node graph
and resource manager.
- Add support for custom resmplers.
- Add ma_decoder_get_data_format().
- Add support for disabling denormals on the audio thread.

instead.
- API CHANGE: Remove the onLog callback from the context config and replaced with a more
flexible system. See the documentation for how to use logging.
- API CHANGE: Remove MA_LOG_LEVEL_VERBOSE and add MA_LOG_LEVEL_DEBUG. Logs using the
MA_LOG_LEVEL_DEBUG logging level will only be output when miniaudio is compiled with the
MA_DEBUG_OUTPUT option.
- API CHANGE: MA_LOG_LEVEL has been removed. All log levels will be posted, except for
MA_LOG_LEVEL_DEBUG which will only be output when MA_DEBUG_OUTPUT is enabled.
- API CHANGE: Rename ma_resource_format to ma_encoding_format.
- API CHANGE: Remove all encoding-specific initialization routines for decoders. Use the

- Fix a linking error when MA_DEBUG_OUTPUT is not enabled.
- Fix an error where ma_log_postv() does not return a value.
- OpenSL: Fix a bug with setting of stream types and recording presets.
0.10.37 - 2021-07-06
- Fix a bug with log message formatting.
- Fix build when compiling with MA_NO_THREADING.
- Minor updates to channel mapping.
0.10.36 - 2021-07-03
- Add support for custom decoding backends.
- Fix some bugs with the Vorbis decoder.
- PulseAudio: Fix a bug with channel mapping.
- PulseAudio: Fix a bug where miniaudio does not fall back to a supported format when PulseAudio
defaults to a format not known to miniaudio.
- OpenSL: Fix a crash when initializing a capture device when a recording preset other than the
default is specified.
- Silence some warnings when compiling with MA_DEBUG_OUTPUT
- Improvements to logging. See the `ma_log` API for details. The logCallback variable used by
ma_context has been deprecated and will be replaced with the new system in version 0.11.
- Initialize an `ma_log` object with `ma_log_init()`.
- Register a callback with `ma_log_register_callback()`.
- In the context config, set `pLog` to your `ma_log` object and stop using `logCallback`.
- Prep work for some upcoming changes to data sources. These changes are still compatible with
existing code, however code will need to be updated in preparation for version 0.11 which will
be breaking. You should make these changes now for any custom data sources:
- Change your base data source object from `ma_data_source_callbacks` to `ma_data_source_base`.
- Call `ma_data_source_init()` for your base object in your custom data source's initialization
routine. This takes a config object which includes a pointer to a vtable which is now where
your custom callbacks are defined.
- Call `ma_data_source_uninit()` in your custom data source's uninitialization routine. This
doesn't currently do anything, but it placeholder in case some future uninitialization code
is required to be added at a later date.
v0.10.35 - 2021-04-27

- Amalgamation of dr_wav, dr_flac and dr_mp3. With this change, including the header section of these libraries before the implementation of miniaudio is no
longer required. Decoding of WAV, FLAC and MP3 should be supported seamlessly without any additional libraries. Decoders can be excluded from the build
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.

- 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()
- ma_decoder_init_vfs_flac()
- ma_decoder_init_vfs_mp3()
- ma_decoder_init_vfs_vorbis()

- 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:
- ma_get_default_buffer_size_in_milliseconds()
- ma_get_default_buffer_size_in_frames()
- API CHANGE: 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.
- API CHANGE: The ma_sine_wave API has been replaced with ma_waveform. The following APIs have been removed:
- ma_sine_wave_init()
- ma_sine_wave_read_f32()
- ma_sine_wave_read_f32_ex()
- API CHANGE: ma_convert_frames() has been updated to take an extra parameter which is the size of the output buffer in PCM frames. Parameters have also been
reordered.
- API CHANGE: ma_convert_frames_ex() has been changed to take a pointer to a ma_data_converter_config object to specify the input and output formats to
convert between.
- API CHANGE: ma_calculate_frame_count_after_src() has been renamed to ma_calculate_frame_count_after_resampling().
- Add support for the following filters:
- Biquad (ma_biquad)

- Second order notching (ma_notch2)
- Second order low shelf (ma_loshelf2)
- Second order high shelf (ma_hishelf2)
- Add waveform generation API (ma_waveform) with support for the following:
- Sine
- Square
- Triangle
- Sawtooth
- Add noise generation API (ma_noise) with support for the following:
- White
- Pink
- Brownian
- Add encoding API (ma_encoder). This only supports outputting to WAV files via dr_wav.
- Add ma_result_description() which is used to retrieve a human readable description of a given result code.
- Result codes have been changed. Binding maintainers will need to update their result code constants.
- More meaningful result codes are now returned when a file fails to open.
- Internal functions have all been made static where possible.
- Fix potential crash when ma_device object's are not aligned to MA_SIMD_ALIGNMENT.
- Fix a bug in ma_decoder_get_length_in_pcm_frames() where it was returning the length based on the internal sample rate rather than the output sample rate.
- Fix bugs in some backends where the device is not drained properly in ma_device_stop().
- Improvements to documentation.
v0.9.10 - 2020-01-15
- Fix compilation errors due to #if/#endif mismatches.
- WASAPI: Fix a bug where automatic stream routing is being performed for devices that are initialized with an explicit device ID.
- iOS: Fix a crash on device uninitialization.
v0.9.9 - 2020-01-09
- Fix compilation errors with MinGW.
- Fix compilation errors when compiling on Apple platforms.
- WASAPI: Add support for disabling hardware offloading.
- WASAPI: Add support for disabling automatic stream routing.
- Core Audio: Fix bugs in the case where the internal device uses deinterleaved buffers.
- Core Audio: Add support for controlling the session category (AVAudioSessionCategory) and options (AVAudioSessionCategoryOptions).
- JACK: Fix bug where incorrect ports are connected.
v0.9.8 - 2019-10-07
- WASAPI: Fix a potential deadlock when starting a full-duplex device.
- WASAPI: Enable automatic resampling by default. Disable with config.wasapi.noAutoConvertSRC.
- Core Audio: Fix bugs with automatic stream routing.
- Add support for controlling whether or not the content of the output buffer passed in to the data callback is pre-initialized
to zero. By default it will be initialized to zero, but this can be changed by setting noPreZeroedOutputBuffer in the device
config. Setting noPreZeroedOutputBuffer to true will leave the contents undefined.
- Add support for clipping samples after the data callback has returned. This only applies when the playback sample format is
configured as ma_format_f32. If you are doing clipping yourself, you can disable this overhead by setting noClip to true in
the device config.
- Add support for master volume control for devices.
- Use ma_device_set_master_volume() to set the volume to a factor between 0 and 1, where 0 is silence and 1 is full volume.
- Use ma_device_set_master_volume_db() to set the volume in decibels where 0 is full volume and < 0 reduces the volume.
- Fix warnings emitted by GCC when `__inline__` is undefined or defined as nothing.
v0.9.7 - 2019-08-28
- Add support for loopback mode (WASAPI only).
- To use this, set the device type to ma_device_type_loopback, and then fill out the capture section of the device config.
- If you need to capture from a specific output device, set the capture device ID to that of a playback device.
- Fix a crash when an error is posted in ma_device_init().
- Fix a compilation error when compiling for ARM architectures.
- Fix a bug with the audio(4) backend where the device is incorrectly being opened in non-blocking mode.
- Fix memory leaks in the Core Audio backend.

v0.9.6 - 2019-08-04
- Add support for loading decoders using a wchar_t string for file paths.
- Don't trigger an assert when ma_device_start() is called on a device that is already started. This will now log a warning
and return MA_INVALID_OPERATION. The same applies for ma_device_stop().
- Try fixing an issue with PulseAudio taking a long time to start playback.
- Fix a bug in ma_convert_frames() and ma_convert_frames_ex().
- Fix memory leaks in the WASAPI backend.
- Fix a compilation error with Visual Studio 2010.
v0.9.5 - 2019-05-21
- Add logging to ma_dlopen() and ma_dlsym().
- Add ma_decoder_get_length_in_pcm_frames().
- Fix a bug with capture on the OpenSL|ES backend.
- Fix a bug with the ALSA backend where a device would not restart after being stopped.
v0.9.4 - 2019-05-06
- Add support for C89. With this change, miniaudio should compile clean with GCC/Clang with "-std=c89 -ansi -pedantic" and
Microsoft compilers back to VC6. Other compilers should also work, but have not been tested.
v0.9.3 - 2019-04-19
- Fix compiler errors on GCC when compiling with -std=c99.
v0.9.2 - 2019-04-08
- Add support for per-context user data.
- Fix a potential bug with context configs.
- Fix some bugs with PulseAudio.
v0.9.1 - 2019-03-17
- Fix a bug where the output buffer is not getting zeroed out before calling the data callback. This happens when
the device is running in passthrough mode (not doing any data conversion).
- Fix an issue where the data callback is getting called too frequently on the WASAPI and DirectSound backends.
- Fix error on the UWP build.
- Fix a build error on Apple platforms.
v0.9 - 2019-03-06
- Rebranded to "miniaudio". All namespaces have been renamed from "mal" to "ma".
- API CHANGE: ma_device_init() and ma_device_config_init() have changed significantly:
- The device type, device ID and user data pointer have moved from ma_device_init() to the config.
- All variations of ma_device_config_init_*() have been removed in favor of just ma_device_config_init().
- ma_device_config_init() now takes only one parameter which is the device type. All other properties need
to be set on the returned object directly.
- The onDataCallback and onStopCallback members of ma_device_config have been renamed to "dataCallback"
and "stopCallback".
- The ID of the physical device is now split into two: one for the playback device and the other for the
capture device. This is required for full-duplex. These are named "pPlaybackDeviceID" and "pCaptureDeviceID".
- API CHANGE: The data callback has changed. It now uses a unified callback for all device types rather than
being separate for each. It now takes two pointers - one containing input data and the other output data. This
design in required for full-duplex. The return value is now void instead of the number of frames written. The
new callback looks like the following:
void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
- API CHANGE: Remove the log callback parameter from ma_context_config_init(). With this change,
ma_context_config_init() now takes no parameters and the log callback is set via the structure directly. The
new policy for config initialization is that only mandatory settings are passed in to *_config_init(). The
"onLog" member of ma_context_config has been renamed to "logCallback".
- API CHANGE: Remove ma_device_get_buffer_size_in_bytes().
- API CHANGE: Rename decoding APIs to "pcm_frames" convention.
- mal_decoder_read() -> ma_decoder_read_pcm_frames()
- mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
- API CHANGE: Rename sine wave reading APIs to f32 convention.
- mal_sine_wave_read() -> ma_sine_wave_read_f32()
- mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
- API CHANGE: Remove some deprecated APIs
- mal_device_set_recv_callback()
- mal_device_set_send_callback()
- mal_src_set_input_sample_rate()
- mal_src_set_output_sample_rate()
- API CHANGE: Add log level to the log callback. New signature:
- void on_log(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
- API CHANGE: Changes to result codes. Constants have changed and unused codes have been removed. If you're
a binding mainainer you will need to update your result code constants.
- API CHANGE: Change the order of the ma_backend enums to priority order. If you are a binding maintainer, you
will need to update.
- API CHANGE: Rename mal_dsp to ma_pcm_converter. All functions have been renamed from mal_dsp_*() to
ma_pcm_converter_*(). All structures have been renamed from mal_dsp* to ma_pcm_converter*.
- API CHANGE: Reorder parameters of ma_decoder_read_pcm_frames() to be consistent with the new parameter order scheme.
- The resampling algorithm has been changed from sinc to linear. The rationale for this is that the sinc implementation
is too inefficient right now. This will hopefully be improved at a later date.
- Device initialization will no longer fall back to shared mode if exclusive mode is requested but is unusable.
With this change, if you request an device in exclusive mode, but exclusive mode is not supported, it will not
automatically fall back to shared mode. The client will need to reinitialize the device in shared mode if that's
what they want.
- Add ring buffer API. This is ma_rb and ma_pcm_rb, the difference being that ma_rb operates on bytes and
ma_pcm_rb operates on PCM frames.
- Add Web Audio backend. This is used when compiling with Emscripten. The SDL backend, which was previously
used for web support, will be removed in a future version.
- Add AAudio backend (Android Audio). This is the new priority backend for Android. Support for AAudio starts
with Android 8. OpenSL|ES is used as a fallback for older versions of Android.
- Remove OpenAL and SDL backends.
- Fix a possible deadlock when rapidly stopping the device after it has started.
- Update documentation.
- Change licensing to a choice of public domain _or_ MIT-0 (No Attribution).
v0.8.14 - 2018-12-16
- Core Audio: Fix a bug where the device state is not set correctly after stopping.
- Add support for custom weights to the channel router.
- Update decoders to use updated APIs in dr_flac, dr_mp3 and dr_wav.
v0.8.13 - 2018-12-04
- Core Audio: Fix a bug with channel mapping.
- Fix a bug with channel routing where the back/left and back/right channels have the wrong weight.
v0.8.12 - 2018-11-27

- Fix a bug with the SDL backend where device initialization fails.
v0.8.8 - 2018-09-14
- Fix Linux build with the ALSA backend.
- Minor documentation fix.
v0.8.7 - 2018-09-12
- Fix a bug with UWP detection.
v0.8.6 - 2018-08-26
- Automatically switch the internal device when the default device is unplugged. Note that this is still in the
early stages and not all backends handle this the same way. As of this version, this will not detect a default
device switch when changed from the operating system's audio preferences (unless the backend itself handles
this automatically). This is not supported in exclusive mode.
- WASAPI and Core Audio: Add support for stream routing. When the application is using a default device and the
user switches the default device via the operating system's audio preferences, miniaudio will automatically switch
the internal device to the new default. This is not supported in exclusive mode.
- WASAPI: Add support for hardware offloading via IAudioClient2. Only supported on Windows 8 and newer.
- WASAPI: Add support for low-latency shared mode via IAudioClient3. Only supported on Windows 10 and newer.
- Add support for compiling the UWP build as C.
- mal_device_set_recv_callback() and mal_device_set_send_callback() have been deprecated. You must now set this
when the device is initialized with mal_device_init*(). These will be removed in version 0.9.0.
v0.8.5 - 2018-08-12
- Add support for specifying the size of a device's buffer in milliseconds. You can still set the buffer size in
frames if that suits you. When bufferSizeInFrames is 0, bufferSizeInMilliseconds will be used. If both are non-0
then bufferSizeInFrames will take priority. If both are set to 0 the default buffer size is used.
- Add support for the audio(4) backend to OpenBSD.
- Fix a bug with the ALSA backend that was causing problems on Raspberry Pi. This significantly improves the
Raspberry Pi experience.
- Fix a bug where an incorrect number of samples is returned from sinc resampling.
- Add support for setting the value to be passed to internal calls to CoInitializeEx().
- WASAPI and WinMM: Stop the device when it is unplugged.
v0.8.4 - 2018-08-06
- Add sndio backend for OpenBSD.
- Add audio(4) backend for NetBSD.
- Drop support for the OSS backend on everything except FreeBSD and DragonFly BSD.
- Formats are now native-endian (were previously little-endian).
- Mark some APIs as deprecated:
- mal_src_set_input_sample_rate() and mal_src_set_output_sample_rate() are replaced with mal_src_set_sample_rate().
- mal_dsp_set_input_sample_rate() and mal_dsp_set_output_sample_rate() are replaced with mal_dsp_set_sample_rate().
- Fix a bug when capturing using the WASAPI backend.
- Fix some aliasing issues with resampling, specifically when increasing the sample rate.
- Fix warnings.
v0.8.3 - 2018-07-15
- Fix a crackling bug when resampling in capture mode.
- Core Audio: Fix a bug where capture does not work.
- ALSA: Fix a bug where the worker thread can get stuck in an infinite loop.
- PulseAudio: Fix a bug where mal_context_init() succeeds when PulseAudio is unusable.
- JACK: Fix a bug where mal_context_init() succeeds when JACK is unusable.
v0.8.2 - 2018-07-07
- Fix a bug on macOS with Core Audio where the internal callback is not called.
v0.8.1 - 2018-07-06
- Fix compilation errors and warnings.
v0.8 - 2018-07-05
- Changed MAL_IMPLEMENTATION to MINI_AL_IMPLEMENTATION for consistency with other libraries. The old
way is still supported for now, but you should update as it may be removed in the future.
- API CHANGE: Replace device enumeration APIs. mal_enumerate_devices() has been replaced with
mal_context_get_devices(). An additional low-level device enumration API has been introduced called
mal_context_enumerate_devices() which uses a callback to report devices.
- API CHANGE: Rename mal_get_sample_size_in_bytes() to mal_get_bytes_per_sample() and add
mal_get_bytes_per_frame().
- API CHANGE: Replace mal_device_config.preferExclusiveMode with mal_device_config.shareMode.
- This new config can be set to mal_share_mode_shared (default) or mal_share_mode_exclusive.
- API CHANGE: Remove excludeNullDevice from mal_context_config.alsa.
- API CHANGE: Rename MAL_MAX_SAMPLE_SIZE_IN_BYTES to MAL_MAX_PCM_SAMPLE_SIZE_IN_BYTES.
- API CHANGE: Change the default channel mapping to the standard Microsoft mapping.
- API CHANGE: Remove backend-specific result codes.
- API CHANGE: Changes to the format conversion APIs (mal_pcm_f32_to_s16(), etc.)
- Add support for Core Audio (Apple).
- Add support for PulseAudio.
- This is the highest priority backend on Linux (higher priority than ALSA) since it is commonly
installed by default on many of the popular distros and offer's more seamless integration on
platforms where PulseAudio is used. In addition, if PulseAudio is installed and running (which
is extremely common), it's better to just use PulseAudio directly rather than going through the
"pulse" ALSA plugin (which is what the "default" ALSA device is likely set to).
- Add support for JACK.
- Remove dependency on asound.h for the ALSA backend. This means the ALSA development packages are no
longer required to build miniaudio.
- Remove dependency on dsound.h for the DirectSound backend. This fixes build issues with some
distributions of MinGW.
- Remove dependency on audioclient.h for the WASAPI backend. This fixes build issues with some
distributions of MinGW.
- Add support for dithering to format conversion.
- Add support for configuring the priority of the worker thread.
- Add a sine wave generator.
- Improve efficiency of sample rate conversion.
- Introduce the notion of standard channel maps. Use mal_get_standard_channel_map().
- Introduce the notion of default device configurations. A default config uses the same configuration
as the backend's internal device, and as such results in a pass-through data transmission pipeline.
- Add support for passing in NULL for the device config in mal_device_init(), which uses a default
config. This requires manually calling mal_device_set_send/recv_callback().
- Add support for decoding from raw PCM data (mal_decoder_init_raw(), etc.)
- Make mal_device_init_ex() more robust.
- Make some APIs more const-correct.
- Fix errors with SDL detection on Apple platforms.
- Fix errors with OpenAL detection.
- Fix some memory leaks.
- Fix a bug with opening decoders from memory.
- Early work on SSE2, AVX2 and NEON optimizations.
- Miscellaneous bug fixes.
- Documentation updates.
v0.7 - 2018-02-25
- API CHANGE: Change mal_src_read_frames() and mal_dsp_read_frames() to use 64-bit sample counts.
- Add decoder APIs for loading WAV, FLAC, Vorbis and MP3 files.
- Allow opening of devices without a context.
- In this case the context is created and managed internally by the device.
- Change the default channel mapping to the same as that used by FLAC.
- Fix build errors with macOS.
v0.6c - 2018-02-12
- Fix build errors with BSD/OSS.
v0.6b - 2018-02-03
- 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.
- Fixes and improvements for Raspberry Pi.
- Warning fixes.
v0.5 - 2017-11-11
- API CHANGE: The mal_context_init() function now takes a pointer to a mal_context_config object for
configuring the context. The works in the same kind of way as the device config. The rationale for this
change is to give applications better control over context-level properties, add support for backend-
specific configurations, and support extensibility without breaking the API.
- API CHANGE: The alsa.preferPlugHW device config variable has been removed since it's not really useful for
anything anymore.
- ALSA: By default, device enumeration will now only enumerate over unique card/device pairs. Applications
can enable verbose device enumeration by setting the alsa.useVerboseDeviceEnumeration context config
variable.
- ALSA: When opening a device in shared mode (the default), the dmix/dsnoop plugin will be prioritized. If
this fails it will fall back to the hw plugin. With this change the preferExclusiveMode config is now
honored. Note that this does not happen when alsa.useVerboseDeviceEnumeration is set to true (see above)
which is by design.
- ALSA: Add support for excluding the "null" device using the alsa.excludeNullDevice context config variable.
- ALSA: Fix a bug with channel mapping which causes an assertion to fail.
- Fix errors with enumeration when pInfo is set to NULL.
- OSS: Fix a bug when starting a device when the client sends 0 samples for the initial buffer fill.
v0.4 - 2017-11-05
- API CHANGE: The log callback is now per-context rather than per-device and as is thus now passed to
mal_context_init(). The rationale for this change is that it allows applications to capture diagnostic
messages at the context level. Previously this was only available at the device level.
- API CHANGE: The device config passed to mal_device_init() is now const.
- Added support for OSS which enables support on BSD platforms.
- Added support for WinMM (waveOut/waveIn).
- Added support for UWP (Universal Windows Platform) applications. Currently C++ only.
- Added support for exclusive mode for selected backends. Currently supported on WASAPI.
- POSIX builds no longer require explicit linking to libpthread (-lpthread).
- ALSA: Explicit linking to libasound (-lasound) is no longer required.
- ALSA: Latency improvements.
- ALSA: Use MMAP mode where available. This can be disabled with the alsa.noMMap config.
- ALSA: Use "hw" devices instead of "plughw" devices by default. This can be disabled with the
alsa.preferPlugHW config.
- WASAPI is now the highest priority backend on Windows platforms.
- Fixed an error with sample rate conversion which was causing crackling when capturing.
- Improved error handling.
- Improved compiler support.
- Miscellaneous bug fixes.
v0.3 - 2017-06-19
- API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for
enumerating and creating devices. Now, applications must first create a context, and then use that to
enumerate and create devices. The reason for this change is to ensure device enumeration and creation is
tied to the same backend. In addition, some backends are better suited to this design.
- API CHANGE: Removed the rewinding APIs because they're too inconsistent across the different backends, hard
to test and maintain, and just generally unreliable.
- Added helper APIs for initializing mal_device_config objects.
- Null Backend: Fixed a crash when recording.
- Fixed build for UWP.
- Added support for f32 formats to the OpenSL|ES backend.
- Added initial implementation of the WASAPI backend.
- Added initial implementation of the OpenAL backend.
- Added support for low quality linear sample rate conversion.
- Added early support for basic channel mapping.
v0.2 - 2016-10-28
- API CHANGE: Add user data pointer as the last parameter to mal_device_init(). The rationale for this
change is to ensure the logging callback has access to the user data during initialization.
- API CHANGE: Have device configuration properties be passed to mal_device_init() via a structure. Rationale:
1) The number of parameters is just getting too much.
2) It makes it a bit easier to add new configuration properties in the future. In particular, there's a
chance there will be support added for backend-specific properties.
- Dropped support for f64, A-law and Mu-law formats since they just aren't common enough to justify the
added maintenance cost.
- DirectSound: Increased the default buffer size for capture devices.
- Added initial implementation of the OpenSL|ES backend.
v0.1 - 2016-10-21
- Initial versioned release.
