- Audacity has now caught up with Apple’s “notarization system”. Audacity on Mac is notarized and runs on Catalina.
- They have split the recording/playing time off from the selection toolbar and it can now be dragged to make it larger. This is particularly for people recording themselves playing a musical instrument, where they will typically be further from the screen when playing and benefit from a larger numerical display.
- The new toolbar can be “unlocked” from the foot of the screen, and made larger still, for more distant viewing.
- They have added a new optional mode for viewing audio. In this new mode you can see both the waveform and a spectrogram at the same time. Previously, you would switch back and forth between them if you wanted.
- To access multi-view mode, you click on the down-pointing triangle beside the track name in the panel on the left side of the wave. This will drop-down a menu with options, including multi-view mode.
