What to change
Kept: the voice stays the same, only faster or slower. Shifted: like a tape played fast — higher when faster, deeper when slower.
Slowing down invents no frames: at 0.25× a 30 fps video plays at 7.5 frames a second.

The video never leaves this tab: the browser itself reads it, changes it and writes a new file. No upload, no queue, and no size limit but your own memory.
