Extend A Song

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

This tool makes a song longer by repeating sections of the track you already have, not by tacking on silence, a fade, or AI-generated music. You set a target length, and Audjust reaches it by reusing internal sections. Because it detects beats and where sections begin and end, the repeats land on the beat, so the longer version sounds like part of the original instead of an obvious loop.

To use it, open the song in your browser. Upload an MP3 or WAV. The tool analyzes the track and marks its beats and section boundaries. Type the length you want, longer than the original, and it builds the extended version from the best-matching sections. Preview it, move where the repeat happens if needed, and download the result. Nothing installs, and there's no signup.

A common reason to extend a song is matching it to a fixed runtime. If a slideshow, video, or reel runs three and a half minutes but the track ends at two and a half, you can grow the song to fill the gap without a jarring jump back to the start.

It's also useful for walk-on music and performances, where a piece needs to keep going until a moment lands rather than cutting out early.

One thing to know: extending works best when the song has a steady repeating part to draw from. A point inside a chorus or verse joins more cleanly than a one-off intro or ending.

Does it add new music that wasn't there? No. It rearranges and repeats parts of your existing track to hit the length you ask for, keeping the original sound intact.
