Markers (sometimes called cues) are locations that you define in a waveform. Markers make it easy to navigate within a waveform to make a selection, perform edits, or play back audio.
In Adobe Audition, a marker can be either a point or a range. A point refers to a specific time position within a waveform (for instance, 1:08.566 from the start of the file). A range has both a start time and an end time (for example, all of the waveform from 1:08.566 to 3:07.379). You can drag start and end markers for a range to different times.
In the timeline at the top of the Editor panel, markers have white handles you can select, drag, or right‑click to access additional commands.
