Sonic surgery on any audio file, stacked one move at a time: stretch time without touching pitch, shift pitch without touching time, run the tape at the wrong speed, split the sound into its tone and its noise, crush the bits, reverse it. Each transform applies to the whole sound and stacks on the last — undo walks back, and the result exports as a WAV. Nothing is uploaded; the audio never leaves this page.
