Abstract:

The Faust programming language is a high-level language for digital signal processing with special support for real-time plugin environments such as Pure Data (PD), LADSPA, and many others. This tutorial describes how to make PD, LADSPA, and VST plugins, focusing on a simple example of white noise filtered by a variable resonator. Additionally, generation of an 8-voiced MIDI synthesizer from Faust source and the faust2pd script is illustrated.
