SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It is free and open source software available for Windows, macOS, and Linux.

SuperCollider features three major components:

SuperCollider was developed by James McCartney and originally released in 1996. In 2002, he generously released it as free software under the GNU General Public License. It is now maintained and developed by an active and enthusiastic community.


Examples

// whose frequency depends on the horizontal mouse pointer position
