Csound is an open-source sound and music computing system. Originally written by Barry Vercoe, Csound is developed in the C programming language and derives from the earliest of computer music software (from Max Matthews' MUSIC-IV to Vercoe's MUSIC-360, then MUSIC-11, then Csound). It has evolved from its non-realtime, desktop application roots to become a commandline compiler, a realtime sound server, and library capable of realtime synthesis and processing. Since Csound 6, Csound supports live coding.
This section will be further developed over time. For now, please see the Csound Reference Manual or FLOSS Csound Manual for more information about Csound.
