Scrolling Through a Zoomed-In Audio Clip
If you zoom in to the waveform display area, you won’t be able to see all of the displayed
waveform at once. There are three ways you can navigate through a zoomed-in audio
clip:
• If you play back your audio clip and then stop playback: The waveform display area shows
the section of your audio clip that the playhead moved to.
• If you click or drag in the Viewer’s scrubber bar: The playhead and view inside the
waveform display area match the position where you clicked or dragged.
• If you want to move to another portion of the audio clip without moving the playhead: Use
the Zoom slider.
The length of the scroll bar under the waveform display area represents the total duration
of your audio clip.
Note: Although this section covers how to scroll through waveform displays in the audio
tabs of the Viewer, you can also use these instructions for scrolling through waveform
displays of sequence clips in the Timeline.
To scroll horizontally through a zoomed-in clip in the Viewer
Do one of the following:
µ
Drag the Zoom slider left or right.
The displayed area of the audio waveform moves in the direction you drag.
µ
Click the scroll arrows at either end of the scroll bar to move the displayed area of the
audio waveform incrementally to the left or right.
µ
Click inside the scroll bar to the left or right of the Zoom slider to move the displayed
area of the audio waveform by one length of the Zoom slider’s current scale.
µ
Press the Up Arrow or Down Arrow key to move the visible area of the audio waveform
between the beginning, In point, Out point, and end of your clip.
Using the J, K, and L Keys to Hear Subtle Details
When an audio clip is displayed in the Viewer, you hear a fragmented version of the sound
as you drag the playhead (or scrub through the clip). You can drag the playhead in the
ruler above the waveform in the Viewer or in the waveform display area to scrub through
the clip. This can be extremely useful for quickly navigating through a clip but will probably
not be very helpful for making detailed audio edits.
To hear audio more clearly as you move through it at different speeds, use the J, K, and
L keys to play your clip in the Viewer. Unlike the scrubber bar, which skips samples to
give the illusion of faster playback at the cost of stuttery-sounding audio, the J, K, and L
keys actually shift the pitch of the audio you’re playing back, enabling you to hear all the
subtle details of the audio at various speeds, both slower and faster than real time.
