FAQ
Is my audio uploaded anywhere?
No. The loop is built entirely in your browser with the Web Audio API. Your file never leaves your device, so it works offline and stays private.
How does the seamless loop work?
The end of the clip is crossfaded into the beginning using equal-power curves, so when it repeats there’s no click or silent gap — the join is inaudible. The result is shorter than the original by the crossfade length.
What does “Repeats” do?
“1 (loop-ready)” gives you one seamless unit to set on repeat in any player or app. Choosing 2×, 4× or 8× bakes that many copies into a single longer file.
