• Reset button: This button deletes all marked keyframes on both the level overlay and
the pan overlay of the currently selected audio track, and resets the level and pan values
to their original captured states (0 dB for the audio level, and –1 for the pan level).
• Drag hand: Use this to drag the current audio clip to the Canvas, the Timeline, or the
Browser. This control is necessary because clicking the waveform itself moves the
playhead to the frame on which you clicked.
• Ruler: When you’re looking at the contents of an audio tab in the Viewer, you’ll see
two playheads, both of which are locked together. The normal Viewer playhead is
located in the scrubber bar below the waveform display area, but there’s also a second
playhead within the waveform display area.
The ruler above the waveform display area shows the currently displayed range of your
clip. If you zoom all the way out (press Shift-Z), this ruler shows the clip from its start
point to its end point, and the movement of the Viewer playhead in the scrubber bar
matches that of the playhead in the waveform display area.
The playhead in the waveform display area lets you move around in an audio clip with
more precision, using the waveform itself for reference as you perform edits or set
keyframes for level and pan (down to 1/100 of a frame, if necessary). Clicking anywhere
on the ruler or in the waveform display area moves the playhead to that frame in your
audio clip. You can also drag the playhead to scrub through the clip, or shuttle through
the clip using the shuttle control or the J, K, and L keys. If you hold down the Shift key
while dragging the playhead in the waveform display area, you can move the playhead
in increments of 1/100 of a frame, which lets you trim edits at a subframe level.
