- API CHANGE: Refactor data conversion APIs
- ma_format_converter has been removed. Use ma_convert_pcm_frames_format() instead.
- ma_channel_router has been replaced with ma_channel_converter.
- ma_src has been replaced with ma_resampler
- ma_pcm_converter has been replaced with ma_data_converter
- API CHANGE: Add support for custom memory allocation callbacks. The following APIs have been updated to take an extra parameter for the allocation
callbacks:
- ma_malloc()
- ma_realloc()
- ma_free()
- ma_aligned_malloc()
- ma_aligned_free()
- ma_rb_init() / ma_rb_init_ex()
- ma_pcm_rb_init() / ma_pcm_rb_init_ex()
- API CHANGE: Simplify latency specification in device configurations. The bufferSizeInFrames and bufferSizeInMilliseconds parameters have been replaced with
periodSizeInFrames and periodSizeInMilliseconds respectively. The previous variables defined the size of the entire buffer, whereas the new ones define the
size of a period. The following APIs have been removed since they are no longer relevant:
- 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)
- First order low-pass (ma_lpf1)
- Second order low-pass (ma_lpf2)
- Low-pass with configurable order (ma_lpf)
- First order high-pass (ma_hpf1)
- Second order high-pass (ma_hpf2)
- High-pass with configurable order (ma_hpf)
- Second order band-pass (ma_bpf2)
- Band-pass with configurable order (ma_bpf)
- Second order peaking EQ (ma_peak2)
- 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.

- 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.

- 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.

- 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.

- 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.
- Minor refactoring to the WinMM, ALSA, PulseAudio, OSS, audio(4), sndio and null backends.

- 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.
