Music Extender

This music extender makes a song longer without it sounding looped or padded. Instead of fading out early or repeating a chunk awkwardly, it finds the beats and section boundaries in the track, then stretches the timeline by repeating whole musical phrases where they fit. The result lands on the length you set and still plays as one continuous song.

To use it, open the editor in your browser and load an MP3 or WAV by uploading a file. The track gets analyzed for its beats and sections. Type the length you want, longer than the original, and the tool rebuilds the song at the boundaries it found. Preview it, nudge a join if one feels off, then export.

The usual reason to extend a song is filling time. If your video, slideshow, or reel runs four minutes and the track is three, you can pull the music out to match instead of letting it cut off or restart. The same helps when a walk-on, dance routine, or presentation segment needs to run longer than the recording allows.

One thing to know: extending works best on songs with clear, repeating structure, like verses and choruses. A continuous build or a spoken recording gives the tool fewer matching points, so stretching those a long way can sound loose at the joins.

The question most people ask is whether it adds new, AI-generated music. It doesn't. It rearranges and repeats the song's own parts to reach your target length, so every note you hear came from the original track. It's the same editor for the other direction too: shorten a song or trim a section, and it stitches the cut so you don't hear a hard edit.
