Overtone website masthead

According to the website, Overtone is a “live-coding environment and audio collaboration platform that’s free for everyone to download, hack on and make crazy-cool sounds either individually or in groups.” It is “a musical programming library written in Clojure which uses the SuperCollider audio engine and synthesis server under the covers.”

For a taste of what kind of sounds can be made in Overtone, check out this band’s website. Overtone also supports integration with Quil and Shadertone to integrate synchronized visuals with Overtone audio.
