This page is for when a track is too short and you need it to run longer. Audjust extends music by detecting natural beats and section boundaries, then repeating the right parts so the longer version flows instead of jumping or restarting. No signup, no install, nothing to download first.

To use it, open the tool and upload an audio file (MP3 and WAV both work). The track gets analyzed, then you set the new length you want. Audjust rebuilds the song to that target by extending sections from the inside, and you can preview before exporting.

A common reason to extend a song is matching it to something longer than itself: a three-minute slideshow that outlasts its track, a dance or routine that needs the music to keep going, or background audio for a video that has to fill the whole runtime.

It also helps when a song almost fits. If your edit needs 2:45 and the track ends at 2:30, you can add the missing seconds in the middle instead of looping the file end to end.

One thing to know: extending works best when you add full musical sections rather than a few odd seconds, since the cut points land on beats. If a target length sounds slightly off, nudge it by a second or two to land on a cleaner boundary.

People often ask whether this is real extending or just a loop. It isn't AI-generated music and it isn't a track played twice. It places repeats at musical seams so the longer version holds together, and you set the exact final length.
