The Audacity Team have announced the release of Audacity v1.3.7 (Beta) for Windows, Mac OS X and Linux/Unix. This is primarily a bug-fix release which significantly improves stability and usability, especially on Mac OS X. It incorporates some new features too, including DirectSound device support for Windows.

Cross-Platform Bug Fixes include:

• Muting/soloing caused incorrect channel results in exported stereo files.
• 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.

Platform-specific Bug Fixes:

• 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.

Other changes:

• As a first step towards improving latency correction, a fixed rather than variable correction is now applied.
• Numerous minor interface fixes and improvements.
