Frequently asked
Is my audio uploaded anywhere?
No. Every clip is decoded, merged, and re-encoded entirely in your browser.
Can I combine clips with different sample rates?
Yes. Every clip is automatically resampled to match the first one before merging, so pitch and speed stay consistent.
What does the crossfade slider do?
At 0 seconds, clips are joined with a hard cut. Above 0, each clip fades into the next over that many seconds instead.
