Short history

Audacity was started by Dominic Mazzoni and Roger Dannenberg in the fall of 1999 as part of a research project at Carnegie Mellon University. Audacity was initially released as an open-source audio editor at SourceForge.net in May 2000.

We got to version Audacity 1.0 of by June 2002. This version was downloaded well over a million times and was widely regarded as a useful and very promising program.

Subsequently other people started helping with development. Less than a year and a half later, we introduced the Audacity 1.2 series, containing hundreds more features, complete support for professional-quality 24-bit and 32-bit audio, a complete Manual and support for many different languages. 1.2.6 was downloaded over 40 million times.

Since then, we produced a successful Beta 1.3 series with significantly enhanced features which served as the starting point for the current 2.0 series..

Dozens of people have contributed to Audacity over the years and today, Audacity is being developed by a team of volunteers located in many different countries. Audacity is distributed under the terms of the GNU General Public License (GPL). You are free to use this program for any personal, educational or commercial purpose. Audacity is now localized to many languages other than English.
