Chapter 11 Edit audio regions in the Audio Track Editor 343
Split and join audio regions in the Audio Track Editor
You can split an audio region into segments in the Audio Track Editor, and move the segments so
that they play back at a different point in time.
You can also join regions or region segments from audio recordings into a single region. Regions
from audio Apple Loops, and audio regions that have been transposed can’t be joined.
To be joined, audio regions must be adjacent to each other on the same track. If you join
segments of compressed audio files, the files are converted, by default, to PCM format (the file
type is set in the Audio > General preferences pane).
Split an audio region
m Select the Scissors tool, then click the point where you want to split the region.
You can scrub regions to find the point where you want to cut by dragging across the regions
with the Scissors tool. You can also split regions by selecting them in the Tracks area, then
selecting Edit > Split > Regions at Playhead.
Before moving or deleting a segment of a split audio region, click the region to select it.

Snap edits to zero crossings in the Audio Track Editor
When Show Advanced Tools is selected in the Advanced preferences pane, you can snap
edits you make in the Audio Track Editor to zero crossings. Making edits, such as trimming
or splitting audio regions, snap to zero crossings helps ensure that no “click” or other noise is
produced at the edit position.
Set edits to snap to zero crossings
m Choose Edit > Snap Edits to Zero Crossings from the Audio Track Editor menu bar.
