Audacity for Mac

What's new in this version:

Dropout detection:
- New feature Dropout detection is controlled from a setting in Recording Preferences called "Detect dropouts"
- 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. Dropouts may be caused by a disk drive that cannot keep up with the recording. This can happen, for example, with a slow USB or network drive, or if antivirus software is slowing writing to disk, or if other activity on the computer is slowing the computer down
- When recording stops, a Warning message is shown and a label track, called "Dropouts", is added showing the lost parts, labeled with consecutive numbers

Improved zooming:
Zooming with the mouse wheel - Mouse wheel zooming has been changed so that the focus for the zoom is:
- With the mouse pointer outside the selection, the leftmost or rightmost edge of the current selection, (if a selection exists)
- Mouse pointer position will be used as the zoom focus if the mouse position is inside the current selection, (if a selection exists)
- If no selection is present, zoom focus is as it was before and is taken as the mouse pointer position

Zoom toggle:
- A new command has been introduced, Zoom Toggle, accessed by a new button or by View > Zoom > Zoom Toggle (shortcut Shift + Z)
- Zoom Toggle toggles between two pre-defined zoom levels. These presets are user selectable in Tracks Preferences
- Defaults are normal Default Zoom level and 4 Pixels per Sample (which shows a fraction of a second of audio as samples)
- Either of the two presets can be changed in Tracks Preferences using the dropdown menus

Vertical zooming changes:
Simple Vertical Scrolling:
- A context menu has been introduced for the Vertical Scale. This is activated by right-clicking in the Vertical Scale

Advanced Vertical Zooming:
- Left-click, and click&drag, in the Vertical Scale remain available as a user-selectable option. The default setting is "off",
- You can turn on advanced mode for vertical zooming from Edit > Preferences > Tracks Behaviors and selecting Advanced Vertical Zooming

Extra menu:
- A new Extra menu has been created from consolidating the Ext-Bar and Ext-Command menus that were introduced in the previous 2.2.1 release

Theme tweaks:
Hover Appearance:
- In dark theme, the change in appearance of sliders when you hover over them is greater than before
- In light and dark themes, buttons such as 'pause' and 'pin' now highlight when you hover over them and they are down. Previously there was no visible change
- The hover effect for buttons when they are up has been changed to work better in conjunction with this change

Icon Appearance:
- In dark theme the microphone and speaker icons are now brighter and not dulled as they were before

Other changes:
- For menu commands that are enabled (not grayed-out) if you hold the Shift key and click on the sub-menu item, instead of executing the command the Keyboard Preferences pop open at the chosen command. You can then change that (or any other) shortcut binding
- Interface Preferences has been upgraded so when selecting languages the proper spelling of these languages is shown with accented and special characters
- The Index page in the Manual has been upgraded - so that now any item that can be clicked on/through in the front page imagemap now has a corresponding text entry in the index (this is primarily as an aid to VI (Visually Impaired) users) Additionally the Index has been divided into alphabetic sections to aid readability
