This can be viewed as dragging the audio past a playback point, much like dragging a reel-to-reel tape past the playback head.
Procedure
-
Zoom in on the wave window or the montage window, so that you get a good visual feedback.
-
On the transport bar, activate Jog and Shuttle.
A vertical line is shown in the middle of the wave/montage window. This is the playback point.
-
Click in the area above the time ruler and drag to the left or right, to play back the audio.
Dragging to the left of the line plays the audio forwards, dragging to the right plays the audio backwards.
