The Audio Editor shows a close-up view of part of an audio track, displaying the audio waveform of the track’s regions in a time grid.
In the Audio 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 Editor, and zoom the amplitude of the waveforms in audio regions. Edits you make in the Audio Editor are nondestructive, so you can always return to your original recordings.
You can also correct the pitch of audio material in the Audio Editor. For more information, see Correct the pitch of regions on an audio track. Using Flex Time, you can edit the timing of audio material in the Audio Editor. For more information, see Edit the timing of notes and beats.
