Audacity – Sound Editing Made Easy
A free alternative to expensive sound editing software, Audacity does all the recording and editing and is much simpler and faster to use than other pricey software. It will also convert tapes and records into digital recordings or CDs, edit MP3 and WAV sound files, cut, copy, splice, and mix sounds together and change the speed or pitch of a recording. Audacity even has an Audition-like noise reduction feature that allows you to select a noise profile and then remove the profile from the selection.
