Keynote: Open Embedded Sound Processing and Synthesis With Faust

Faust is a domain-specific functional programming language for real-time audio Digital Signal Processing (DSP), supported by a global community of developers, researchers, hobbyists, and artists. The Faust compiler can be used to generate highly optimized code in various lower-level languages ranging from C++ to VHDL. In recent years, Faust has been used in the context of real-time audio DSP on embedded systems such as microcontrollers, digital signal processors, FPGAs, etc., leading to various open applications such as digital musical instruments, equipment for sound engineers, immersive sound systems, etc.

This talk begins with a brief introduction to Faust and its ecosystem, highlighting how its functional paradigm facilitates the implementation of complex audio algorithms with minimal code. We will then demonstrate Faust’s application in both existing and custom open embedded systems, showcasing the creation of new musical instruments and cutting-edge sound systems. Throughout the talk, numerous live music and sound examples will be presented.
