Audacity for Mac is a Universal Binary for OS X 10.5 to 10.11.x. Audacity runs best with at least 1 GB RAM and a 1 GHz processor (2 GB RAM/2 GHz on OS X 10.7 or later). For lengthy multi-track projects, we recommend a minimum of 2 GB RAM and 2 GHz processor (4 GB RAM on OS X 10.7 or later). Today I will show a little bit about Voice Over for the Mac. I tested the screen readers on Microsoft Edge, Internet Explorer, Groove Music, Skype, Dropbox, Microsoft Word, Audacity, Feedback, and the Settings app. Narrator now uses something called scan mode. You can toggle this on and off by pressing caps lock and space bar.

When this setting is 'on' (default setting) Audacity will detect dropouts (brief gaps in the recording) and will insert zeroes into the recording to keep the other good parts synchronized. These silent spans will make the dropouts more obvious, but keep the duration of the recording correct. When recording stops, a Warning message box alerts the user and a label track, called 'Dropouts', is added showing the lost parts, labeled with consecutive numbers.
  • * Improved horizontal zooming For this release we have improved the way zooming using your mouse wheel works and provided a new Zoom Toggle function.
  • * Improved vertical zooming We have added a context menu to the vertical scale to control vertical zooming Previous vertical zooming methods (left-click in the vertical ruler, left-drag in the vertical ruler) remain available by selecting 'Advanced Vertical Zooming' in Track Behaviors Preferences.

You can then change that (or any other) shortcut binding.
  • * Language selection in Preferences Interface Preferences has been upgraded so when selecting languages the proper spelling of these languages is shown with accented and special characters.
  • Bug Fixes
  • * Multiple use of 'Save As' to the existing open project can result in data corruption/loss
  • * Crash undoing during record, using Discard button of History window
  • * Exporting audio in compressed formats to device with insufficient space produces inconsistent/truncated results
  • * In Export Multiple, Cancel does not remove the file that is in progress when Cancel is chosen
  • * Unicode page encodings fixed ( 001a° 001a001a 001a°)

  • * (Mac) Equalization: 'Telephone' curve displays a flat line, no sound on Preview
  • * Toolbars: open undocked if previously not shown, unless Reset Toolbars first
  • * Analysis effects that create labels should give focus to label track
  • * Control value may be out of range when using FloatingPointValidator

  • The setting is per track and not per project so you can have multiple colorways
  • in the same project.
  • * 'Save Other' reverts to 'Export' in the File menu
  • When we made the menu changes for 2.2.0 we introduced an entry into the File menu
  • called 'Save Other' which led to a sub-menu for exporting various audio formats.
  • Many users were confused by this change and found it hard to find where they could
  • export audio from. So for 2.2.1 we have changed that menu entry to be File > Export.
  • Bug Fixes
  • * Release 2.2.1 is mainly a maintenance release.
  • Soon after the release of 2.2.0 we discovered some problematical bugs in Audacity:

  • inaccessible instance of Audacity
  • Bug #1770 - Crash applying certain chain files
  • Bug #1783 - Preview fails when selection extends before zero
