The Audio Track Editor displays the audio waveform of the regions on an audio track. In the Audio Track Editor, you can copy, paste, move, trim, split, and join audio regions. Using the Audio Track Editor grid, you can precisely align edits with specific points in time.
Audio Track Editor menu bar: Contains menus with region editing commands and functions, as well as buttons for Flex editing, selecting editing tools, and zooming the editor.
Audio Track Editor inspector: When Flex Pitch is turned on, contains controls for quantizing time and pitch, correcting pitch, and adjusting gain.
Waveform display: Shows the audio waveform for the region on a time grid.
Ruler: Shows time divisions so you can align regions and make edits at precise time positions.
Playhead: Reflects the current playback position.
When Flex Pitch is turned on, you can quantize the timing and pitch of audio regions, and adjust their pitch and gain in the Audio Track Editor inspector. All edits in the Audio Track Editor are non-destructive, so you can always return to your original recordings.
