Scrubbing Sync Points
While viewing an audio waveform can be a good way to set a sync point, a waveform display may not always reveal the desired spot in the audio material. By scrubbing while moving the sync point over an audio waveform, you can listen for the exact location to place the sync point.
 
To scrub while dragging the sync point:
1 If you want the sync point to snap to the current Grid value when you finish scrubbing, set the Edit mode to Grid (see Edit Modes).
2 Select the Scrubber tool.
3 Drag the sync point to a new location. The sync point scrubs the audio as you move it.
