Trim, crop, or delete audio

Trim audio at the beginning or end of a file

Click the Zoom Out Full button  to display trim handles in the Editor panel, and drag either handle inward.
If trim handles are visually distracting, deselect View > Trim Handles.

Crop to selected audio

Select the audio you want to keep, and then choose Edit > Crop.

Delete audio in the middle of a file

Select the audio you want to remove, and then press the Delete key.

When you edit audio from a video file, trimming, cropping, and deleting silence audio without changing file length, maintaining video synchronization. (See Maintaining video synchronization when editing audio.)
Use trim handles to quickly remove the beginning or end of files.
