SuperCollider Build Status Appveyor

SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It consists of:

  • scsynth, a real-time audio server with hundreds of unit generators ("UGens") for audio analysis, synthesis, and processing
  • supernova, an alternative server to scsynth with support for parallel DSP on multi-core processors
  • sclang, an interpreted programming language that controls the servers
  • scide, an editing environment for sclang with an integrated help system

sclang comes with its own package manager, called Quarks. scsynth and supernova both support third-party plugins via C and C++ APIs.

SuperCollider is written in C++11 using several third-party libraries, including Qt and Boost.


macOS and Windows builds for stable releases are provided at our downloads page. See the macOS README and Windows README for instructions on usage, and how to build SC yourself.

To get the latest stable version, Linux users will need to build SuperCollider themselves. See the Linux README for instructions.

Platform requirements

The minimum supported version of macOS is 10.10 Yosemite; the minimum supported version of Windows is Windows Vista.


The official docs can be viewed in the SuperCollider IDE's built-in documentation browser. You can also view them online at

We recommend the following resources for learning SC:


You can sign up for mailing lists, and view the archives for sc-users and sc-dev.

We also have a forum and a Slack chat.

Please read our adopted code of conduct, which applies to all the above communities.
