Repeat Audio Online

This tool repeats a short clip or a single section back to back so it fills the time you need without an awkward jump. You pick the part, set the total length you're aiming for, and Audjust lays down enough repeats to reach it, joining them on detected beats so the loop point doesn't click or stutter.

To use it, upload an MP3 or WAV, then mark the start and end of the part you want to repeat. Enter the total length, and it adds enough clean repeats to fill that time. Preview the join, then export. It's free, runs in your browser, and needs no install.

A common case is stretching a 40-second backing track into a steady eight minutes to cover a whole performance or a timed exercise. Another is repeating a few bars to match the exact length of a video or reel, down to the second.

One tip: pick start and end points that fall on the beat. Because Audjust aligns repeats to detected beats, a clean musical boundary joins far more smoothly than a cut made mid-note.

The usual worry is whether a loop sounds glued together or obviously repeated. Because the join lands on the beat instead of a hard copy-paste seam, the same passage can run several times and still feel continuous.
