Digidesign is an American digital audio technology company. It was founded in 1984 by Peter Gotcher and Evan Brooks. The company began as a project to raise money for the founders’ band, selling EPROM chips for drum machines.

Digidesign’s flagship software product is Pro Tools, which comes in three variations: Pro Tools|HD, Pro Tools LE, and Pro Tools M-Powered.

Pro Tools|HD requires a Digidesign TDM system and interface, and is intended for professional recording studios. Pro Tools LE is a complete package intended for home users and some post-production facilities. The package includes the Pro Tools LE software and hardware such as the M-Box 2 or Digi 003. Pro Tools M-Powered is simply the Pro Tools application adapted to run on M-Audio hardware, and is generally comparable in power to LE systems.

Digidesign also makes a number of products for the Pro Tools platform, including several software plug-ins. They also manufacture a wide variety of hardware add-ons for Pro Tools, such as audio interfaces, MIDI interfaces, Synchronizers, and control surfaces. In the spring of 2005 they introduced a system for live sound mixing called VENUE.
