Part VI
Use the J, K, and L keys to shuttle through your clips, and learn to listen for the edit
points you want. Once you have set In and Out points, you can use the Play In to Out
(Shift-\) and Play to Out (Shift-P) commands to preview your edits. As you do this, you’ll
find yourself trimming one or two frames at a time and then setting new edit points,
repeating the process until you’ve found the perfect audio editing points.
Learning About the Audio Controls in the Viewer
When you click an audio tab in the Viewer, the controls at the bottom of the window
are the same as those in the Video tab. These controls allow you to navigate through
your clip, set In and Out points and markers, create split edits, and so on. The In and
Out points that you see in an audio tab are the same as the In and Out points shown in
the Video tab. Similarly, the two timecode fields in the top area of the window are the
same as those in the Video tab. For more information on those controls and fields, see
“
The following controls are found only in audio tabs:
 Waveform display area: Displays a graphical representation of the audio clip, showing
the sample values of your audio over time. If you zoom in on the waveform display, you
can see progressively more detail in your waveform. Clicking anywhere in the waveform
area moves the playhead to that frame, and dragging scrubs through the clip.
 Pan overlay line: Drag this line up or down to change the pan for this clip. If you add
keyframes to the overlay, you can create changes in pan over time.
 Level overlay line: Drag this line up or down to change the sound level. If you add
keyframes to the overlay, you can create changes in level over time.
 Level slider: This slider adjusts the amplitude, or volume, of the currently selected
audio clip between +12 and –inf dB. As you drag the slider, the number in the dB
field and the level overlay line are both updated.
