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 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 application.
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 Audacity version.
