About

rust.audio is a collection of resources dedicated to the development of audio applications in the Rust programming language. These topics vary from general DSP, to synthesis, to plugins and associated crates.

Resources

Audio plugin formats

VST

GPLv3 or Proprietary ➜

VST can refer to several different versions of the VST format by Steinberg. VST2 was one of the most common standards, but is now unlicensed. Instead, VST3 is recommended and is generally supported in most DAWs. Note that the Rust vst3-sys crate currently relies on GPLv3 code.

Crates

AudioUnit

Proprietary ➜

AudioUnit (AU) is only available on Apple platforms. AU v2 is simlar to VST, and AU v3 follows an Apple framework approach, which is harder to implement without Apple tools. Currently, no Rust libraries implement the AudioUnit standard.

Resources

LV2

ISC ➜

LV2 is only supported on Linux with a few exceptions. One interesting feature is that all LV2 plugin hosts and plugins are backwards compatible with previous versions.

Crates

CLAP

MIT ➜

CLAP is a relatively new plugin format with permissive licensing. It does not currently have wide support outside of Bitwig.
