If you have an MP3 and want a clean section out of it, Audjust detects the beats and section changes in the track and shows them on a timeline. Instead of guessing where a phrase starts and ends, you drag the start and end handles onto those marked points and cut there, so the piece you keep begins and ends on the beat instead of mid-note.

To use it, open the editor in your browser and drag in your MP3 (WAV works too). Audjust analyzes the file and marks the beats and boundaries. Set your start and end on the part you want, play it back to check the edges, then export. No signup, no install, free.

Because the cut lands on a real boundary, the section ends cleanly rather than with a click or a half-beat hanging off. The same detection is what lets Audjust shorten or extend a whole track without an abrupt jump, so trimming to a clean section works the same way.

One thing to know: this cuts sections inside a file you already have. It does not name what song a sample came from or search a library for matches, so use it on audio you have the rights to.

A practical tip: zoom in around your cut points before exporting. The beat markers get you close, but nudging the start a few milliseconds onto the attack of the note gives the cleanest edge.

The question most people ask is whether it is free and needs an account. It is free, runs right in your browser, and needs no signup or download.
