Faust (Functional Audio Stream) is a functional programming
language for sound synthesis and audio processing with a
strong focus on the design of synthesizers, musical
instruments, audio effects, etc. created at the GRAME-CNCM
Research Department. Faust targets high-performance signal
processing applications and audio plug-ins for a variety
of platforms and standards.

The core component of Faust is its compiler. It allows to
"translate" any Faust digital signal processing (DSP)
specification to a wide range of non-domain specific
languages such as C++, C, LLVM bit code, WebAssembly,
Rust, etc. In this regard, Faust can be seen as an alternative
to C++ but is much simpler and intuitive to learn.
