Audacity® is free, open source software for recording and editing sounds. It is available for Mac OS X, Microsoft Windows, GNU/Linux, and other operating systems.

Bug fixes for:

• Crash, slow launch or excessive CPU/memory use arising from automatic VST support:
  • VST instrument plug-ins should now be correctly ignored
  • VST effects now scanned only at start of first session that detects them, then cached
  • Effects are now not loaded or opened until needed
  • New "Effects" tab in Preferences to enable/disable VST effects and enable VST rescan on next launch
• Default View Mode now works
• Chains now always apply their stored parameters rather than those last used in Effect menu
• Non-MP3 files imported via drag or Recent Files caused crash if filter in file open window set to MP3
• AAC exports (using the optional FFmpeg library) silenced
• Generating audio always fitted the project in the window; fit now done only if generating in new track
• View menu items/shortcuts incorrectly disabled when playing or recording
• DTMF generator defaulted to zero duration on open
• Unwanted interactions between linked audio and label tracks
• (Windows XP)  Failure to launch on some machines due to "incorrect configuration" issue
• (Windows)  Crash importing a stereo file while a screen reader such as JAWS is running
• (Mac OS X) :
  • Audio Units effects applied to all tracks in project even if not selected
  • QuickTime importer now handles files greater than 16-bit or 64000 Hz
• Various other interface bugs

Improvements:

• Compressor: new option to compress based on peaks, improved attack and decay time support
• Mixer Board: improved design, more responsive meters and now interacts fully with Track Panel in main window
