Extend Song Length

This tool makes a song longer so it reaches the exact duration you set. Instead of looping the whole track or pasting in a repeat that jumps, it finds the beats and section boundaries inside the song and repeats and bridges those sections, so the longer version still plays as one continuous track.

To use it: open the editor, upload an audio file, and let it analyze the track. Set a target length longer than the original, and Audjust rebuilds the song to fit. Preview the result, then export. No signup, no install, and it works with MP3, WAV, and other common files.

This helps when a song falls just short of what you need. If a video or slideshow runs 3:00 but your track ends at 2:20, push it out to 3:00 so the music covers the whole clip. The same goes for a performance, a presentation, or a background that has to fill a fixed block of time.

One thing to know: extending repeats and joins existing sections, so it adds no new music. Songs with clear verses and choruses give it more places to add length cleanly than a short or very repetitive clip does.

People usually ask whether the result sounds stretched or slowed down. It doesn't. The pitch and tempo stay exactly the same; only the arrangement gets longer, joined at points where the beat already lines up.
