Faust is a functional programming language for realtime signal processing and synthesis that targets high-performance signal processing applications and audio plugins. The paper gives a brief introduction to Faust and discusses its interfaces to Q, a general purpose functional programming language, and SuperCollider, an object-oriented sound synthesis language and engine.

This document is a quick-reference to the Faust language (version 0.9.8), a programming language for real-time signal processing and synthesis that targets high-performance signal processing applications and audio plugins.
