Audacity is a free software program for recording and editing audio. You can use Audacity to record sounds onto your computer with a microphone or it can open and edit audio files, including tracks downloaded from the internet or copied from CDs. Audacity can open and save MP3, WAV, AIFF, and several other types of audio files.
You can edit recordings with Audacity the same way you edit text with a word processor. Audacity can cut, copy, splice, and mix sounds together. Filters are included for altering speed and pitch, adding echo or reverb, removing noise from recordings, and more. To get started, click here to download the Audacity software.
