Cross-platform audio in Rust
Go to file
Chris Morgan 2679ea845f impl Debug for Device (#253)
The internal alsa, null and emscripten Device implementations already
implemented Debug; but the coreaudio and wasapi ones, and therefore
also the wrapper, did not.

I decided to eschew the `Device(…)` wrapping in the outer layer
(hence a custom implementation rather than `#[derive(Debug)]`),
because `Device(Device)`, `Device(Device { … })` and so forth all
look better without the extra `Device(…)` wrapping.

On the wasapi and coreaudio implementations I put both the pointer and
name. Name because it’s useful, pointer because on Windows at least
I believe duplicated names are possible. (e.g. two monitors that include
monitors, of the same type; I haven’t strictly confirmed this, because I
killed those off harshly on my machine and don’t want to reinstate
them.)

I do not have access to a macOS device to confirm that the coreaudio
implementation is sane, but I think it is.

CPAL - Cross-Platform Audio Library

Build Status Crates.io docs.rs

Low-level library for audio input and output in pure Rust.

This library currently supports the following:

  • Enumerate all available audio devices.
  • Get the current default input and output devices.
  • Enumerate known supported input and output stream formats for a device.
  • Get the current default input and output stream formats for a device.
  • Build and run input and output PCM streams on a chosen device with a given stream format.

Currently supported backends include:

  • Linux (via ALSA)
  • Windows
  • macOS (via CoreAudio)
  • iOS (via CoreAudio)
  • Emscripten

Note that on Linux, the ALSA development files are required. These are provided as part of the libasound2-dev package on Debian and Ubuntu distributions and alsa-lib-devel on Fedora.
