Audacity is a free opensource audio editing and recording software. Audacity can run on Linux, Windows and Mac OSX. Audacity can manipulate digital audio wave forms. In addition to recording sounds directly from within the program, it imports many sound file formats, including WAV, AIFF, AU, IRCAM, MP, and Ogg Vorbis. With Audacity, you can edit wave data larger than the physical memory size of your computer.
