In addition to recording audio from multiple sources, Audacity can be used for post-processing of all types of audio, including effects such as normalization, trimming, and fading in and out. In April 2021, it was announced that Muse Group (owners of MuseScore and Ultimate Guitar) would acquire the Audacity trademark and continue to develop the application, which remains free and open source. Most of its changes were eventually incorporated into the mainline version and the fork ended. Over the years, additional volunteer contributors emerged, including James Crook who started the fork DarkAudacity to experiment with a new look and other UX changes. Mazzoni eventually left CMU to pursue software development and in particular development of Audacity, with Dannenberg remaining at CMU and continuing development of Nyquist, a scripting language which Audacity uses for some effects.

On May 28, 2000, Audacity was released as Audacity 0.8 to the public. The project was started in the fall of 1999 by Dominic Mazzoni and Roger Dannenberg at Carnegie Mellon University, initially under the name CMU Visual Audio.
