In the Audio Track Editor, you can move and trim audio regions, split and join them, and edit them in other ways. You can scroll and zoom the Audio Track Editor, and zoom the amplitude of the waveforms in audio regions. Edits you make in the Audio Track Editor are non-destructive, so you can always return to your original recordings.
You can also quantize and edit the pitch of audio material in the Audio Track Editor using Flex Pitch. For more information, see ruler showing time divisions, and a menu bar with local menus, PDF
