Music Extender Online Free

This free online music extender makes a song longer. Give it a target length and it fills that time by repeating sections at musically sensible points, so the result holds together instead of looping a few seconds over and over.

To use it, open a song from your computer (MP3 or WAV both work). Audjust analyzes the beats and section boundaries, then you type the length you want, drag the end handle, or pick which part to repeat. Preview it, fix any join that feels off, and export.

This helps when a backing track or instrumental ends before your routine, slideshow, or speech does, and you need another 30 or 60 seconds without an obvious restart. It also works for padding a track to a longer video so the music doesn't run out mid-scene.

Worth knowing: extending sounds best when the song has a clear, repeating section to draw from, like a chorus or a steady groove. The tool looks for spots that line up on the beat, so a join between two matching sections is far cleaner than one built around a one-off intro.

The most common question: does this slow the song down to make it longer? No. The pitch and tempo stay the same. It adds length by repeating real parts of the track at natural boundaries, not by slowing playback.
