Undo or Cancel Audio Recording
Once you have recorded an audio track and the transport is stopped, you can undo the record take.
To undo an audio recording:

Once the Transport has been stopped, choose
Edit > Undo Record Audio.
The track is restored to its previous state and material is discarded as follows:
• When in normal Record mode, only the most recent take is discarded.
• When in Loop Record mode, all takes from each record pass are discarded.
• When using QuickPunch, all punches from the last recording pass are discarded.

If you undo a record pass during recording, any previously undone record passes are removed from the project.
If no actions are available to undo, the menu displays a grayed out Can’t Undo.
