New Features in Audacity 2.0

Audacity 2.0 is our current version. It has dozens of new features, developed in the 1.3 series. It replaces all previous versions, especially 1.2.6 and 1.3.14. See New Features in 1.3 for changes during the 1.3 series. See also Release Notes for more details.

Some of the major changes in 2.0.0 over 1.2.6 are:
Many effects significantly improved, especially Equalization, Noise Removal and Normalize. Vocal Remover now included plus GVerb on Windows and Mac. VAMP analysis plug-ins now supported.
Improved label tracks with Sync-Lock Tracks feature in the Tracks Menu. Multiple clips per track. Tracks and selections can be fully manipulated using the keyboard. Many more keyboard shortcuts.
New Device Toolbar to manage inputs and outputs. Timer Record feature. 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. Added support for optional FFmpeg library for import/export of AC3/M4A/WMA and import of audio from video files.

Version 1.3.14 | Release Date: 2011-12-11 | Download

Bug fixes:

-Fixes for data loss when encountering corrupted project files. Steps taken to prevent writing of overlong audio data block files.
-Excessive delay occurred when typing into labels in long projects.
-MP2 files could not be imported natively. File types requiring FFmpeg library imported as noise if FFmpeg was unavailable.
-Crashes fixed when dragging tracks. Crash fixed when resetting Toolbars when an audio stream was present.
-Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.

Changes and Improvements:

-Normalize now preserves left-right balance in stereo tracks by default with an option to normalize stereo channels independently.
-Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
-Mix and Render now preserves clip length by not rendering white space before the start of audio, and preserves audio before time zero.
-CleanSpeech Mode has been removed from Preferences but can be run or disabled in 1.3.14 by changing Preferences in a previous Audacity version.
-(OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
