Audio Looper
Cut any section of a track into a loop: set the region, hear it cycle live, tune the crossfade until the seam vanishes, then export the loop repeated as many times as you need. WAV and MP3 out, everything in your browser.
Finding Musical Loop Points
Seamless loops are arithmetic, not luck. One bar of 4/4 lasts 240 divided by the BPM: at 128 BPM that is 1.875 seconds, at 174 BPM 1.379. Pick a start point on a downbeat, then make the region length an exact multiple of the bar length: 4 or 8 bars for grooves, 1 or 2 for tool loops. A loop cut this way lines its own seam up rhythmically, and the crossfade only has to hide the click, not a stumble. Run the source through the Song Key & BPM Finder first for the exact decimal BPM, and use the beats-to-time calculator for the bar math at any tempo.
Crossfade Settings by Material
- Drum grooves: 10 to 30 ms, just enough to remove the click without softening the first kick
- Basslines and melodic loops: 30 to 80 ms; longer fades start to double notes at the seam
- Pads, drones, atmospheres: 200 to 500 ms; the material has no transients to protect, so a long equal-power blend makes the loop truly invisible
- If the seam thumps: your endpoints sit on different parts of the bar; fix the region length before reaching for a longer fade

- Tool pages are built from reusable page logic, internal DJ reference data, and visible on-page calculations. Programmatic reference pages are generated from structured data rather than hand-written one by one.
BPM, key, and genre labels can vary by edit, remaster, detection engine, and DJ software. Use these pages as a practical mixing reference, then verify important tracks in your own library.
