AI Song Extender Free

This page does one job: making a song longer, for free. Audjust analyzes a track, finds its beats and section boundaries, and stretches it to a longer target length by repeating and reconnecting whole musical phrases. Because the joins land on real beats, the extended song keeps its groove instead of sounding like a clumsy loop or a stuttered copy.

To use it, open the editor and upload an MP3 or WAV. Set the new, longer duration you want. Audjust picks natural points to repeat and rejoins them on the beat. Preview it, nudge where the added section sits if you want, then export. No signup, no install, and the processing happens in your browser.

A common reason to extend a song: you have a 90-second video or slideshow but the track runs out at 60 seconds, and you'd rather lengthen the music than awkwardly fade it. It also helps for performances or routines that fill a fixed time slot, or for stretching a short intro into a longer bed.

One thing to know: extending works best inside a song that has repeating sections, like a chorus or a steady beat. A track with no internal repetition, such as a constant build with no loopable part, gives the tool less to work with, so the result may feel more obvious.

The question most people ask: does it actually make new music? No. It doesn't generate new notes or instruments. It rearranges and repeats the song's own audio to reach your target length, which is why the extended version still sounds like the original.
