When you record music, vocals, or sound effects in GarageBand, a graphical representation of your recording — called a region — appears in one of the tracks in Tracks view. You can trim, split, and arrange regions to build songs and other audio projects.
Move an audio region. Drag the region to the left or right to reposition it. If one region is dragged on top of another, the overlapping portion is automatically cut.
Trim a region. Select the region, then drag the lower‑left or lower‑right edge of the region to shorten or lengthen it.
Zoom in for accuracy. Use the horizontal zoom slider in the upper‑right corner of the Tracks area to zoom in the workspace when trimming a region.
Copy and paste regions. Select a region and choose Edit , Copy. Move the playhead to where you’d like the pasted region to start, then choose Edit , Paste.
Split a region. Select a region, then move the playhead to the point where you want to split the region apart. Choose Edit , Split Regions at Playhead.
Delete a region. Select one or more regions, then choose Edit , Delete or press the Delete key.
Edit and enhance a recorded interview for added impact. Split the recording into multiple regions and balance volumes between voices before applying audio presets for a desired effect.
Add transitions between sections of a recorded lecture. Split the region into shorter segments and add Apple Loops to indicate the start and end of each topic.
For even more precise edits, use the Audio Editor, which provides a detailed view of each region. In the Audio Editor, you can move and trim audio regions, split and join them, and edit them in other ways. Edits you make in the Audio Editor are nondestructive, so you can always return to your original recordings.
