294 Part II Rough Editing
 If two audio clip items are linked as a stereo pair, they’re represented in a single Stereo
tab that contains the waveforms of that pair’s left and right audio channels. Level
changes applied to one item are automatically applied to the other. Editing audio as
a stereo pair is useful for intrinsically stereo material, such as music mixed in stereo
and built-in stereo camcorder audio.
Zooming In or Out of the Waveform Display Area
Navigating through audio clips in the Viewer is largely the same as navigating through
video clips in the Video tab. There are some additional features, however, that you
should be aware of.
When you navigate through a clip in the Video tab of the Viewer, you only see the
frame at the location of the playhead. Zooming in to this frame enlarges the visual
image, but doesn’t change your position in time. Waveforms in an audio tab work
differently. Since they represent your entire audio clip, you can navigate through a
waveform as you would a clip in the Timeline. As you move through the waveform,
you’ll notice that the playhead in the scrubber bar under the waveform display area
moves in conjunction with the playhead in the waveform area.
The scrubber bar in the Viewer always represents the entire duration of the clip in the
Viewer. The ruler above the waveform display area, on the other hand, is not so
constrained. Using the Zoom control and the Zoom slider at the bottom of the
waveform display area, you can zoom in and out of the waveform display area in the
Viewer. This expands and contracts the audio ruler, allowing you to see more or less
detail in an audio clip’s waveform. While the smallest unit you can see in the video track
of a clip is a single frame, you can see a clip’s audio waveform in increments as small as
1/100th of a frame.
