Music Extend AI

Music Extend AI is for when a track is too short and you need it to run longer. Audjust analyzes the song, finds its beats and section boundaries, and repeats whole sections (like a chorus or verse) so the extra time lands on a real beat instead of cutting back with an audible seam. You pick the length, and it adds music until the song reaches it.

To use it, open the editor in your browser, upload an MP3 or WAV, and let it analyze the track. Type the duration you want, longer than the original. Audjust extends the song by reusing its sections, you preview the result, then export the file. No signup, no install, nothing to download first.

This helps when a song ends before your video does, say a 90-second reel that needs another 25 seconds of music, or a slideshow, performance, or presentation that has to run a fixed time. Instead of fading or restarting the track, you get a continuous version that fills the slot.

One thing to know: this extends by rearranging music that's already in the recording, so it works best on songs with clear repeating sections or a steady beat. It won't generate new melodies or instruments that weren't there.

Does the longer version sound natural? Because the added time starts and ends on detected beat and section points, it blends into the song rather than sounding like a clipped repeat. Preview it before exporting to confirm it fits your clip.
