rust-portaudio 
Portaudio bindings for Rust.
PortAudio is a free, cross-platform, open-source, audio I/O library. These are the bindings and wrappers for Rust.
Visit the PortAudio website here.
Rust-PortAudio use the same license as PortAudio : the MIT license.
Rust-PortAudio is still in development, so there may be bugs - please feel free to add an issue or even better, submit a PR!
Using rust-portaudio.
To use rust-portaudio in your own project, add it to your Cargo.toml dependencies like so:
[dependencies]
portaudio = "*"
Installation
rust-portaudio will try to detect portaudio on your system and, failing that (or if given the PORTAUDIO_ONLY_STATIC environment variable on the build process), will download and build portaudio statically.
rust-portaudio is built using cargo, so just type cargo build at the root of the rust-portaudio repository.
You can build the tests and examples with cargo test, and the documentation with cargo doc.
