About the Timeline

The Timeline displays a visual representation of a project, showing the point in time when audio clips start playing and their duration. You control when and how long clips play by moving and resizing them in the Timeline.

The Timeline also displays vertical gridlines that make it easy to position clips precisely in time. The gridlines correspond to the divisions of time in the Time ruler. The units of time the gridlines display change depending on the Ruler Units setting in the Project tab and the current zoom level. The Timeline is arranged in three sets of horizontal rows—tracks, busses, and submixes. You add audio clips to tracks, create submixes using busses, and send audio to physical output devices using submixes. For information about working with tracks, busses, and submixes, see Tracks, Busses, Submixes, and the Master Bus.
