Fixes for data loss when encountering corrupted project files. Steps taken to prevent writing of overlong audio data block files.
Excessive delay occurred when typing into labels in long projects.
MP2 files could not be imported natively. File types requiring FFmpeg library imported as noise if FFmpeg was unavailable.
Crashes fixed when dragging tracks. Crash fixed when resetting Toolbars when an audio stream was present.
Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.
Normalize now preserves left-right balance in stereo tracks by default with an option to normalize stereo channels independently.
Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
Mix and Render now preserves clip length by not rendering white space before the start of audio, and preserves audio before time zero.
CleanSpeech Mode has been removed from Preferences but can be run or disabled in 1.3.14 by changing Preferences in a previous Audacity version.
(OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
