Audacity is an open source, cross-platform audio editor and recorder. Audacity can record and play sounds and import and export WAV, AIFF, MP3, and OGG files. Edit your sounds using cut, copy, and paste features (with unlimited undo functionality), mix tracks, 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.

- New Distortion effect, Rhythm Track (was called Click Track) and Sample Data Import (thanks to Steve Daulton). Also effects are no longer grayed-out when in pause.
- New scrub ruler and ‘pinned’ option so the waveform moves and the recording/playing head stays still. (Paul)
- New features in Timer Record (Mark Young & Steve)
- On Mac, audacity.app is now added to /Applications/ directly rather than adding a folder there.
- 64 bugs/annoyances in 2.1.2 fixed of which 15 were long-standing issues. Also lots done (Paul again) to systematically deal with memory leaks.

- Redesigned Meter Toolbars: The default shows separate Record and Playback Meters, half-height so they can be wider while docked, in gradient style.
