Audacity is an audio tool that allows you to record and play sounds, import or export WAV, AIFF or MP3 files. Use it to edit your sounds using Cut, Copy and Paste (with unlimited Undo), mix tracks together, or apply effects to your recordings. Audacity also has a built-in amplitude envelope editor, a customizable spectrogram mode and a frequency analysis window for audio analysis applications. Built-in effects include Bass Boost, Wahwah, and Noise Removal, and it also supports VST plug-in effects.

The Audacity Team is pleased to announce the release of Audacity for Windows, Mac and Linux/Unix. This release removes a significant number of crash or freeze problems and other major bugs. It brings us very close to our goal of a new 2.0 Release. We ask everyone to help us test and let us know of any problems you find. Advanced users are encouraged to test our latest fixes as we make them by downloading our Nightly Builds. We hope a final Beta will follow soon.
