Audacity 2.0 has been released today (04/13/2012)

Audacity, the venerable and much loved open source audio editor, has a 2.0 release today in versions for OS X, Windows and GNU/Linux.

Audacity is great for recording live audio, converting analog sources into digital recordings or CDs, and changing the speed or pitch of a recording. For many podcasters, Audacity is the go-to tool for recording and editing. You can edit Ogg Vorbis, MP3, WAV or AIFF sound files.

Here are new features of Audacity 2.0:

• Many effects are significantly improved, especially Equalization.
• Improved label tracks with Sync-Lock Tracks feature in the Tracks Menu.
• A new Device Toolbar to manage inputs and outputs, a Timer Record feature and a new Mixer Board view with per-track VU meters.
• Automatic Crash Recovery in the event of abnormal program termination.
• Fast "On-Demand" import of WAV/AIFF files if read directly from source. FLAC now fully supported.
