Extend Song

This page makes a song longer. You set a target length, and Audjust extends the track to reach it, repeating and rejoining sections so the result keeps playing instead of looping back in an obvious way. It runs in your browser, it's free, and there's no signup or install. Common files like MP3 and WAV work.

Upload your audio. The tool analyzes the song and finds the beats and section boundaries. Type the duration you want, longer than the original, and it builds the extended version by repeating sections at those boundaries. Preview it, nudge a join if one feels off, then export.

A typical case: a video or reel that runs longer than your music. Instead of the song ending early or restarting with a hard cut, you stretch it to fill the runtime. Another is a performance or presentation with a fixed slot, where the track has to keep going until a cue.

One thing worth knowing: extending works best when the song has a steady, repeating section to draw from. A track with a clear chorus or groove extends more cleanly than a short piece that never repeats anything.

The question most people have is whether this adds new, AI-generated music. It doesn't. It rearranges and repeats the audio you already have, choosing cut points on the beat so the longer version stays smooth and on-tempo.
