AI To Extend Music

Audjust detects the beats and section boundaries in a track, then makes it longer by repeating whole musical sections joined on the beat. Instead of looping the whole song back to the start, it reuses the parts that repeat cleanly, so the longer version keeps its rhythm rather than cutting back abruptly.

To use it, load an MP3 or WAV by uploading a file. The tool analyzes the audio and marks where beats and sections begin. Type the length you need, preview the result, drag the section edges if a join feels off, then export.

This is the tool you want when a track ends before your content does. Push a 90-second song out to cover a three-minute slideshow, dance routine, or product video, hit an exact runtime for a stream, or build a longer intro or outro for a performance.

One thing to know: extending works best on songs with a steady, repeating structure. A track with a clear verse and chorus has obvious section boundaries to reuse, so it lengthens more naturally than a freeform or constantly shifting piece. The closer your target is to a whole number of sections, the smoother the joins sound.

People usually ask whether the longer track sounds looped. Because the added length comes from real sections cut on the beat, the result holds the original rhythm instead of snapping back to the opening bar.
