How To Extend Audio

If a clip ends too soon, you can extend audio right here in your browser. Audjust lengthens a track to the duration you set by repeating natural sections, so the longer version still flows like the original instead of looping abruptly or fading out early.

It reads the beats and section boundaries in your song, then adds time at those points. The added time lands on the beat, so an extra fifteen or thirty seconds sounds like it belongs there.

To do it: load an MP3 or WAV file, type or drag to the length you need, let it find the seams, then preview and download. No signup, no install, nothing to pay.

This helps when a video, slideshow, or reel runs longer than your music. Instead of cutting the visuals or stacking a second copy of the song, you match the audio to the runtime exactly. It also works for stage cues or a presentation that needs a track to fill a fixed slot.

One thing to know: this repeats parts of your existing audio rather than generating new music, and it doesn't slow the track down or change its pitch. So it works best when the song has repeating sections to draw from. A track with a steady groove or chorus extends more cleanly than a short one-off sound effect.

People usually ask whether the longer version sounds obvious. Because the added time lands on real beats and section breaks, most listeners won't spot where it grew. Preview a few target lengths and pick the one that sits most naturally.
