Audacity

Audacity is a free software, cross-platform digital audio editor and recording application. It is available for Windows, Mac OS X, Linux and BSD.

The program is great for small scale audio editing, but may not be the best choice for large scale productions such as movies etc. It is great for voice editing such as voice lower/raising or increasing the speed/volume of a voice.

Audacity was created by Dominic Mazzoni while he was a graduate student at Carnegie Mellon University. Mazzoni now works at Google, but is still the main developer and maintainer of Audacity, with help from many others around the world.

The latest release of Audacity is 1.3.13, a beta, released on 11 April 2011. As of 29 October 2010, it was the 10th most popular download from SourceForge.net, with 72 million downloads.undefinedAudacity won the SourceForge.net 2007 Community Choice Award for Best Project for Multimedia.
