AI Extended Music

If you searched for AI extended music, you probably want a track to run longer than it does now, stretched to a specific length without an obvious copy-paste loop or a jarring jump. This tool does exactly that: you give it a song and a target time, and it works out where to repeat sections so the longer version still flows.

It runs in your browser. It's free, with no signup or install, and it reads common files like MP3 and WAV.

To use it: upload your file, let it analyze the audio, then set a length longer than the original. It detects beats and section boundaries and extends across those natural points, so a chorus or instrumental section repeats on the beat instead of mid-phrase. Preview the result, adjust if needed, and export.

A common case: you have a 2-minute song but a 4-minute slideshow, dance routine, or background loop to fill. Instead of restarting the track halfway through, you get one continuous version that lands right at your target time.

One thing to know: extending works best when a song has a repeatable section to draw from, like a steady groove or a recurring chorus. Tracks that change constantly are harder to lengthen cleanly, so set your target length where a natural section can repeat.

The question most people ask: does it invent new sound? No. It doesn't generate new instruments or melodies. It rearranges and repeats the existing audio on the beat, so the extended track sounds like a longer cut of the same song.
