To zoom in to and out of the audio waveform using the Zoom slider
Do one of the following:
µ
Drag the thumb tabs on either side of the Zoom slider to adjust both ends of your view
at the same time.
If the playhead is visible, it stays centered during the zoom. If the playhead is not visible,
the visible area of the Timeline stays centered.
µ
Hold down the Shift key while you drag one of the thumb tabs from the selected end of
the Zoom slider, while keeping the other thumb tab locked in place.
Zooming in to and out of an audio clip’s waveform using menu commands or keyboard
shortcuts keeps the visible area of the waveform display area centered as you zoom.
To zoom in to and out of the audio waveform using keyboard shortcuts or menu
commands
1 Move the playhead to the position in the waveform display area where you want zooming
to be centered.
2 Do one of the following:
• To zoom in: Choose View > Zoom In, or press Command-Equal Sign (=).
Pressing Command-Equal Sign (=) repeatedly shows more and more detail, down to
the individual frames of your audio clip.
• To zoom out: Choose View > Zoom Out, or press Command-Hyphen (-).
Zooming out reduces the amount of detail and shows more of the audio clip’s waveform.
When the entire clip fits in the waveform display area, zooming out stops.
