|
|
FAUST (Functional Audio Stream) is a functional programming
|
|
language specifically designed for real-time signal processing
|
|
and synthesis. FAUST targets high-performance signal processing
|
|
applications and audio plug-ins for a variety of platforms and
|
|
standards.
|
|
The Faust compiler translates DSP specifications into very
|
|
efficient C++ code. Thanks to the notion of architecture,
|
|
FAUST programs can be easily deployed on a large variety of
|
|
audio platforms and plugin formats (jack, alsa, ladspa, maxmsp,
|
|
puredata, csound, supercollider, pure, vst, coreaudio) without
|
|
any change to the FAUST code.
|
|
|
|
This package has just the compiler, libraries, and headers.
|
|
Install faust2* for specific faust2appl scripts.
