mitchmindtree 06a0f0a3ab Publish 0.8 for new Device and Stream API. Update CHANGELOG. (#209) 2018-02-15 08:47:43 +01:00
mitchmindtree c38bbb26e4 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

mitchmindtree b47e46a4ac Update winapi version from 0.2 to 0.3 (#202)
Adds only the necessary cargo features to reduce compile time and reduce
the chance of linking errors occurring for unused libraries (e.g.
d3d12.dll fails to link on my win10 VM).

I thought I'd try and land this before before working on the wasapi
backend implementation for #201.

Tested both beep.rs and enumerate.rs and they work fine with the update.

mitchmindtree f2728f6bdf 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

mitchmindtree 3952c44c63 [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.

mitchmindtree d09532c36e 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.

2017-10-11 09:31:16 +02:00
egnehots bd88d9d6ff Document RemoteIO as ios unit fallback
iOS provides three I/O (input/output) units. The vast majority of audio-unit applications use the Remote I/O unit, which connects to input and output audio hardware and provides low-latency access to individual incoming and outgoing audio sample values. For VoIP apps, the Voice-Processing I/O unit extends the Remote I/O unit by adding acoustic echo cancelation and other features. To send audio back to your application rather than to output audio hardware, use the Generic Output unit.
