The Audacity Team has announced the release of Audacity v1.3.9 (Beta) for Windows, Mac OS X and Linux/Unix. It contains many bug fixes contributed by their two Google Summer of Code (GSoC) 2009 students. As well as bug fixing, the students' projects involved work on experimental "scripting" and "pre-record level detection" features that will appear in future Audacity versions.
Bug fixes in v1.3.9:
- 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 in v1.3.9:
- 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.
