Hatchling 5169f53304 Added winapi feature "winbase" in windows dependencies
When using cpal as dependency in other project, it was found that cpal
won't build due to unresolved import of winapi::um::winbase. Added the
feature at line 24 in Cargo.toml.

mitchmindtree 391b32f5b2 Update CPAL to version 0.10.0.
This is quite a significant update for CPAL, including a number of
breaking changes. Here is a list of the breaking changes along with
links to where you can find more information:

- A `Host` API has been introduced in #289 along with a follow-up
  refactor in #295. Please see the examples for a demonstration of how
  to update your code. The necessary changes should hopefully be
  minimal. If this has caused you any major difficulty please let us
  know in an issue!
- An ASIO host has been introduced in #292. This adds support for
  Steinberg's ASIO audio driver API on Windows. Please see the ASIO
  section of the README for more information on how to setup CPAL with
  ASIO support for your project.
- The user callback API has been overhauled to emit `StreamEvent`s
  rather than buffers in order to support handling stream errors. #288.
- Error handling in general was overhauled in #286. This meant taking
  advantage of the `failure` crate and adding support for
  backend-specific errors with custom messages. Many unnecessary
  `panic!`s have been removed, but a few remain that would indicate bugs
  in CPAL.

In general, checking out the updated examples will be the easiest way to
get a quick overview on how you can update your own code for these
changes.

The CHANGELOG.md has been updated to include these changes.

mitchmindtree 8f95042b8d Add `asio` cargo feature for optional ASIO support
ASIO introduces quite a few extra crates and requires a fairly
complicated setup process (see the readme), so this feature is disabled
by default.

mitchmindtree a2fe9386af [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

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 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.
