518 Chapter 21 Editing Audio in the Sample Editor
Navigating Audio Files
The Sample Editor offers a number of navigation facilities that make it easy to move to,
and enhance the view of, specific parts of an audio file—making selection and editing
far simpler, faster, and more accurate.
The scroll bars along the bottom and right edges of the Sample Editor scroll through
the detailed waveform display in the usual way.
The zoom controls are also used in the same fashion as in other windows.
Click on the overview to display the area surrounding the Sample Editor playhead in
the detailed waveform display. The overview always displays the entire audio file,
regardless of the zoom level (and selected area) shown in the waveform display.
Quickly Navigating to Specific Positions in Audio Files
If you’re trying to reach a specific point in the audio file, some of the commands listed
below may also be of use to you. These are available in the Sample Editor’s Edit menu,
and as key commands.
 Go to Selection Start (default key command: Left Arrow key)
 Go to Selection End (default key command: Right Arrow key)
 Go to Region Start
 Go to Region End
 Go to Region Anchor (Down Arrow key)
To navigate to the loudest point in an audio file:
m Choose Functions > Search Peak (or use the corresponding key command,
default: Shift-P) to scan the currently selected region for the sample bit with the
greatest amplitude value.
The playhead is placed on this bit in the waveform display.
To navigate to silent passages in your audio file:
m Choose Functions > Search Silence (or use the corresponding key command,
default: Shift-S) to scan the selected audio file (or selection area) for sections
containing silence (digital zero).
The playhead is moved to the start point of the first silent section.
This command can be used repeatedly, to select and remove, or modify, silent sections
in your audio files.
