What the loop tool does
It repeats your audio back to back until it reaches the length you set. One slider takes a short clip up to minutes of continuous sound.
Where looping helps
Use it to stretch background music, ambience or a sound bed to fit a video. It is the fast way to fill a fixed running time without re-recording.
