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.

Features include


Record live audio through a microphone or mixer, or digitize recordings from cassette tapes, vinyl records, or minidiscs. With some sound cards, it can also capture streaming audio.
Dub over existing tracks to create multi-track recordings.
Record up to 16 channels at once (requires multi-channel hardware).
Level meters can monitor volume levels before, during, and after recording.
