Apple Final Cut Pro 7 - Manual (Page 670)

• 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 to 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 to 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 1/100 of a frame.
