64-bit Mac build
The 2.3.1 release of Audacity for macOS is now a 64-bit build and will only run on modern 64-bit Macs, running OSX 10.7 or later.
Note carefully that if you use the LAME library for MP3 export or the FFmpeg library you will need to install the 64-bit versions of those libraries.
FFmpeg is used for importing and exporting a much larger range of audio formats including M4A (AAC), AC3, AMR (narrow band) and WMA.
Scrub Ruler
The Scrub Ruler is now turned "off" by default and is not displayed. The reason we did this was because we found too many users were accidentally clicking in the Scrub Ruler and then finding themselves stuck in Scrubbing mode.
This will only affect you if you opt to reset your preferences settings as part of the 2.3.1 installation, manually reset your preferences or install Audacity for the first time.
If you want/need to turn it back on again use either the Timeline and select Enable Scrub Ruler.
and check the Scrub Ruler to be "on". Or right click in the![]() |
The Scrub and Seek commands are still readily available from the Transport menu. |
Advanced Vertical Zooming
We have added a new command to the Advanced Vertical Zooming "on" or "off".
menu for turningAdvanced Vertical Zooming enables you to use left-click gestures in the Vertical Scale to control zooming (this is in addition to the Simple mode vertical zooming commands available from the right-click context menu in the Vertical Scale).
Micro Fades
Micro fades (introduced in 2.3.0) can reduce the click when playback starts and stops. We've now made this an opt-in feature rather than provide it all the time, this can be set in Playback Preferences.
Regular Interval Labels improvements
We have made some improvements to Regular Interval Labels, accessed by
.In particular we have made it possible to create range labels and not just point labels with this Tool. You can do this by specifying the label length in the new input field Length of label region (seconds)
See this page for full details of how the improved Tool works.
