Need to loop an MP3 or audio file — repeat one section over and over — without a click or gap where it loops back? Upload your file into LoopTube, set the start and end points, and it plays back with a seamless crossfade at the seam — no audible jump when it repeats. Combine it with independent tempo and pitch control to loop a passage at any speed or in any key.
How to Loop a Section of an Audio File
- Upload Your File — Open LoopTube and drop in an MP3, WAV, or other audio file. It loads entirely in your browser.
- Set the A and B Points — Drag the loop markers on the waveform to mark exactly where the section starts and ends.
- Play — It Loops Automatically — The section repeats continuously. Slow the tempo, shift the pitch, or both — the loop keeps repeating seamlessly at your new settings.
Why the Crossfade Matters
Most simple loop tools just jump straight back to the start point, which produces an audible click or a jarring restart every time the section repeats. LoopTube blends the very end of the loop back into its start with a short equal-power crossfade, so the transition is smooth. It's a small detail, but it's the difference between a loop you can listen to for five minutes of focused practice and one that grates after the third repeat.
