Extended Music

When a track runs out before your video, ceremony, or set is over, this tool gives you a longer version that still lands on the beat. You load a song, tell Audjust the length you need, and it repeats and stitches whole sections at musical seams rather than fading out or cutting off.

To use it: open the editor, upload an MP3 or WAV, and set a target duration longer than the original. Audjust detects the beats and section boundaries, repeats parts of the song to reach your length, and joins them on the beat. Preview the result, nudge it if you want, then export.

Two common cases: a three-minute song that needs to cover a five-minute slideshow, and a backing track that has to last a full dance routine or ceremony without stopping halfway.

A tip for better results: the extra length sounds best when it comes from a part that already repeats, like a chorus or a steady groove. A song built around a one-time bridge gives the tool less to reuse, so pick tracks with a clear repeating section when you can.

The usual worry is whether the longer version sounds like an obvious copy-paste. It does not, as long as the added time starts on a real beat, which is what the section splicing is for.
