Adjust a selection to zero-crossing points
For many editing tasks, such as deleting or inserting audio in the middle of a waveform, the best places to make selec-
tions are the points where the amplitude is zero (called zero-crossings). Selecting the zero-crossing points reduces the
chance that an edit will create an audible pop or click. You can easily adjust a selection to the closest zero-crossing
points by using a Zero Crossing command.
❖
Choose Edit > Zero Crossing, and choose one of the following commands:
Adjusts both range boundaries inward to the next zero-crossing point.
Adjust Selection Inward
Adjust Selection Outward
Adjusts the left range boundary leftward to the next zero-crossing point.
Adjust Left Side To Left
Adjust Left Side To Right
Adjust Right Side To Left
Adjust Right Side To Right
Select audio between beats
For some editing tasks, such as constructing drum loops and similar musical phrases, you need to select audio
between beats. Though you can often identify beats by looking for peaks in a waveform, the Find Beats command
makes the task much quicker. After you find beats with this command, Adobe Audition saves them as Beat Markers,
making it easy to locate beats again.
Click in the Main panel to the left of the first beat you want to find.
1
Choose Edit > Find Beats > Find Next Beat (Left Side). The cursor moves to the beginning of the next beat.
2
3 Choose Edit > Find Beats > Find Next Beat (Right Side) to select from the current cursor position to the next beat.
If you want to select more than one beat, choose Edit > Find Beats > Find Next Beat (Right Side) again. Each time
4
you choose this command, Adobe Audition adds the next beat to the selection.

To find beats in material that has fast transient attacks, such as drums, specify a quick Rise Time and a high Decibel
Rise. For material with softer attacks, such as bass, the Rise Time can be slightly slower relative to Decibel Rise.
