Extend Music AI Free

This page is also available in other languages: Deutsch, 한국어, 日本語, Español, Português (Brasil), Français

This page extends a song to a longer length without costing anything or asking you to make an account. You give Audjust a track and a target time, and it fills that time by repeating beats and whole sections from inside the song. Because it lines up natural beat and section boundaries, the longer version flows like the original instead of repeating in an obvious, choppy way.

To use it: upload an MP3 or WAV, wait for Audjust to detect the beats, then type or drag to the length you want. The extended track is built from existing parts of the song, so the style, key, and tempo stay identical. Preview it, then download.

A common reason to extend a song: your video, reel, or slideshow runs longer than the track. Rather than fading the music out early or stacking two copies, you stretch the song to match the full runtime. It also helps with performances or routines that need an extra 30 or 60 seconds at the same pace.

Make sure you have the applicable rights to any audio you submit to Audjust.

A tip: extend by repeating a strong middle or chorus section rather than the intro, since intros rarely sound right when repeated. Audjust suggests cut points, but you can nudge them.

The question most people ask: is this AI that writes new music? No. It doesn't generate new notes or instruments. It rearranges and repeats parts of your own song to reach the longer length, which keeps the result sounding like the original track, and it's free.
