CSound

Csound is a sound design, music synthesis, and signal processing system, providing facilities for composition and performance over a wide range of platforms.

For Haskell there exist several interfaces to CSound:

• hCsound by John Lato provides direct access to CSounds runtime.
• Translation from Haskell expressions to CSound Orchestra and Score expressions written by Matt Zamec and Sarah Eisenstat. This was part of Haskore and is now part of HasSound.
