  • Nyquist effects: pasted unmodified audio into the result, no progress bar, truncation of processed audio on cancel.
  • Noise Removal: pasted unmodified audio into the result, unwanted filtering tail.
  • Uncompressed exports:
    • Export as WAV could be corrupted if overwriting to same file.
    • Export multiple to uncompressed formats only produced 16-bit WAV.
  • Compressed exports:
    • MP3 exports now produce correct bit rate mode, quality and length, with improved metadata visibility in player applications.
    • WMA exports containing metadata are now correct.
  • Restored support for multi-channel recording devices that can record more than two channels using Audacity.

  • Windows Vista: Fixed crash opening Preferences with no sound devices enabled and connected.
  • Mac OS X and Linux:
    • Fixes for spurious clipping, label typing, no shortcuts after running effects.
    • Project rate now always changes to respect that of first imported file.
  • Mac OS X only:
    • Fixes for inactive or corrupted menus and hidden dialogues, portable settings not detected, and inability to set independent Command and Control shortcuts.
    • FFmpeg installer now available.

New Features:

  • F11 Full Screen mode, high-quality "Sliding Time Scale/Pitch Shift" effect, Audio Contrast Analyzer.
  • Windows: sound devices can now be opened using the more efficient DirectSound API.
