Audacity 2.1.2 changes:

Improvements

Effects

Noise Reduction defaults changed.

Interface

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.

Other Changes

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.
