Audacity 2.1.2 changes:
- Noise Reduction defaults changed.
- We’ve made several improvements to the spectrogram view of tracks which are particularly valuable for vocal work.
- New option ‘Spectral Reassignment’. This algorithm deduces a ‘finer’ spectrogram for vocal work.
- Four new Spectrogram scales.
- Improvement to the Pitch (EAC) algorithm – cleaner (sharper) display.
- Spectrogram Settings are now available per-track.
- Upgraded from wxWidgets 2.8.12 to wxWidgets 3.0.2.
- Restructuring of the Preferences Menu
- Restructuring of the Track Dropdown Menu (for the Spectrograms)
- The Noise Reduction "Frequency smoothing" default has been increased to 3 to help avoid metallic artifacts. Resetting Preferences or deleting audacity.cfg will set the new default.
- (Windows) The location of Audacity's work-in-progress folder has been changed, to avoid problems where certain disk cleaners treated them as deletable temporary files.
- Crashes on reading very large .wav and .mp2 files have been fixed.
- Mac OS X
