CPAL - Cross-Platform Audio Library

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.
