# Unreleased
[coreaudio] Fix handling of non-default sample rates for input streams (#214) * [coreaudio] Fix handling of non-default sample rates for input streams Currently when building an input stream the coreaudio backend only specifies the sample rate for the audio unit, however coreaudio requires that the audio unit sample rate matches the device sample rate. This changes the `build_input_stream` behaviour to: 1. Check if the device sample rate differs from the desired one. 2. If so, check that there are no existing audio units using the device at the current sample rate. If there are, panic with a message explaining why. 3. Otherwise, change the device sample rate. 4. Continue building the input stream audio unit as normal. Closes #213. * Update CHANGELOG for coreaudio input stream sample rate fix * Publish 0.8.1 for coreaudio input stream sample rate fix
2018-04-01 11:25:46 +00:00
# Version 0.8.1 (2018-03-18)
- Fix the handling of non-default sample rates for coreaudio input streams.
Publish 0.8 for new Device and Stream API. Update CHANGELOG. (#209)
2018-02-15 07:47:43 +00:00
# Version 0.8.0 (2018-02-15)
Update to a more general Device and Stream API. Add support for input streams (E.g. microphone). Add default format methods. (#201) * Update to a more general Device and Stream API This update prepares for adding input stream support by removing the `Endpoint` type (which only supports output streams) in favour of a more general `Device` type which may support any number of input or output streams. Previously discussed at #117. The name `Voice` has been replaced with the more ubiquitous name `Stream`. See #118 for justification. Also introduces a new `StreamData` which is now passed to the `EventLoop::run` callback rather than the `UnknownTypeBuffer`. `StreamData` allows for passing either `Input` data to be read, or `Output` data to be written. The `beep.rs` example has been updated for the API changes. None of the backends have been updated for this API change yet. Backends will be updated in the following commits. Closes #117. Closes #118. * Update ALSA backend for new `Device` and `Stream` API. * Update wasapi backend for new `Device` and `Stream` API. * Update enumerate.rs example for new `Device` and `Stream` API. * Update coreaudio backend for new `Device` and `Stream` API. * Fix lib doc tests for Device and Stream API update * Update emscripten backend for new `Device` and `Stream` API. * Update null backend for new `Device` and `Stream` API. * Merge match exprs in beep.rs example * Add Input variant along with UnknownTypeInputBuffer and InputBuffer UnknownTypeBuffer and Buffer have been renamed to UnknownTypeOutputBuffer and OutputBuffer respectively. No backends have yet been updated for this name change or the addition of the InputBuffer. * Update null backend for introduction of InputBuffer * Update emscripten backend for introduction of InputBuffer * Make InputBuffer inner field an option to call finish in drop * Update alsa backend for introduction of InputBuffer * Update wasapi backend for introduction of InputBuffer * Update coreaudio backend for introduction of InputBuffer * Update enumerate.rs example to provide more detail about devices The enumerate.rs example now also displays: - Supported input stream formats. - Default input stream format. - Default output stream format. This should also be useful for testing the progress of #201. * Add `record_wav.rs` example for demonstrating input streams Records a ~3 second WAV file to `$CARGO_MANIFEST_DIR/recorded.wav` using the default input device and default input format. Uses hound 3.0 to create and write to the WAV file. This should also be useful for testing the input stream implementations for each different cpal backend. * Implement input stream support for coreaudio backend This implements the following for the coreaudio backend: - Device::supported_input_formats - Device::default_input_format - Device::default_output_format - EventLoop::build_input_stream The `enumerate.rs` and `record_wav.rs` examples now work successfully on macos. * Add `SupportedFormat::cmp_default_heuristics` method This adds a comparison function which compares two `SupportedFormat`s in terms of their priority of use as a default stream format. Some backends (such as ALSA) do not provide a default stream format for their audio devices. In these cases, CPAL attempts to decide on a reasonable default format for the user. To do this we use the "greatest" of all supported stream formats when compared with this method. * Implement input stream support for ALSA backend This implements the following for the ALSA backend: - Device::supported_input_formats - Device::default_input_format - Device::default_output_format - EventLoop::build_input_stream Note that ALSA itself does not give default stream formats for its devices. Thus the newly added `SupportedFormat::cmp_default_heuristics` method is used to determine the most suitable, supported stream format to use as the default. The `enumerate.rs` and `record_wav.rs` examples now work successfully on my linux machine. * Implement input stream support for wasapi backend This implements the following for the wasapi backend: - Device::supported_input_formats - Device::default_input_format - Device::default_output_format - EventLoop::build_input_stream Note that wasapi does not enumerate supported input/output stream formats for its devices. Instead, we query the `IsFormatSupported` method for supported formats ourselves. * Fix some warnings in the alsa backend * Update CHANGELOG for introduction of input streams and related items * Update README to show latest features supported by CPAL * Simplify beep example using Device::default_output_format * Remove old commented code from wasapi/stream.rs
2018-02-12 13:10:24 +00:00

Remove unused `ChannelPosition` API (update all backends and examples accordingly) (#198) * Remove ChannelPosition API This removes the ChannelPosition API from the lib root and updates the ALSA backend and examples accordingly. The other backends have not yet been updated. Related discussion at #187. * Update windows backend to removal of ChannelPosition API The windows backend now assumes the channel position order is equal to the channel position mask order. E.g. channel 0 will always be front left, channel 1 will always be front right, etc. Compiled and ran both examples successfully. * Update coreaudio backend to removal of ChannelPosition API Compiled and ran both examples successfully. * Update emscriptem backend for removal of ChannelPosition API * Update CHANGELOG for ChannelPosition removal
2018-02-04 09:38:06 +00:00
- Remove unused ChannelPosition API.
[macos] Implement Endpoint and Format Enumeration Based on #195. Also implements proper handling of the given `Endpoint` in the macos implementation of the `build_voice` method. Updates to the latest coreaudio-sys and coreaudio-rs which include the additional necessary frameworks. Also adds a line that prints the name of the default device in the `enumeration.rs` example. Updates the CHANGELOG for this PR. Closes #194. Related to #180. Related external issues: - RustAudio/coreaudio-sys#4 - RustAudio/coreaudio-rs#57

Publish v0.6.0 (#190) There does not seem to be any major API breakage, however the emscripten and macos backends have been pretty heavily refactored so I thought it best to bump to 0.6 (rather than 0.5.2) just in case there is any subtle behavioural breakage. Happy to change this to 0.5.2 though if someone can confirm there will be no downstream breakage.

and `EventLoop::pause` that can be used to create, destroy, play and pause voices.
- Added a `VoiceId` struct that is now used to identify a voice owned by an `EventLoop`.
