Among several improvements, keyboard shortcuts can now be allocated to effects, Nyquist plug-ins can be added to Chains and Audacity now has excellent compatibility with the VoiceOver screen reader in Mac.
Release Notes:
Bug fixes
Interface
- Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
- Finding zero crossings could cause the selection to expand into white space at either side of the clip.
- Clips did not drag to another track if mouse was over a selection.
- Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.
Imports, Exports and Files
- Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
- (Mac) Fixed crashes importing MP3 files on PPC machines.
- (Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).
Effects and Analysis
- Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files before On-Demand completed.
- Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.
- Other miscellaneous bug fixes
including fix to prevent zooming with mouse wheel or ball scrolling the content off-screen.
Changes and Improvements
- Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
- Nyquist Effect plug-ins can now be added to Chains.
- New "Paulstretch" effect for extreme slowdown without pitch change.
- New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.

- New Preference (off by default) to retain labels when deleting a selection that snaps to the label without extending past it.

Known issues in Accessibility
Many, but not all parts of the Audacity interface are accessible on Windows to those who can't use a mouse, and/or use a screen reader. It may be possible to make more of Audacity accessible in the longer term. For details, see http://manual.audacityteam.org/man/Accessibility
There are some accessibility bugs in the parts of Audacity that are accessible: Toolbar buttons cannot be operated by pressing either ENTER or Space: ENTER incorrectly moves to the next control and Space starts/stops playback. However the buttons can be operated either by using their shortcut keys, or for users of screen readers by using the Jaws cursor or equivalent. Note: it will be necessary to go to the Keyboard Preferences to set a shortcut for the Play-at-speed button.
For users of JAWS and Window-eyes. when the Silence Generator dialog opens, the duration control is incorrectly read as 0 seconds. However, if you tab round to the control again, the correct value is read.
For users of all screen readers, "and" is read out before the access key character in some controls in Preferences.
Some interface text or markings remain in black when using High Contrast light-on-dark themes, so cannot be read properly
(OS X) Issues with VoiceOver: If you use arrow keys to navigate the Timetext controls in Selection Toolbar, VoiceOver stops reading. Workaround: Use Control-Option-W
Mixer Toolbar input/output sliders are not read, just described as "multiple indicators". The "Graphic EQ" sliders in Equalization *are* read.
Metadata Editor table not read.
Edit Labels dialog not read.
(Linux) If you TAB into "Snap To" in Selection Toolbar, the selection and focus will become trapped. A mouse click elsewhere will be required to free the focus. Workaround: Access the required part of Selection Toolbar with TAB or SHIFT + TAB so as to avoid Snap To. Snap To can be set on or off by exiting Audacity, show hidden files and folders then add or edit the line "SnapTo=1" or "SnapTo=0" (without quotes, for on or off respectively) in ~/.audacity-data/audacity.cfg.
