How it works
- 01
Load a song
Drop in an MP3 or WAV, up to 250 MB and 10 minutes. It opens in your browser and never leaves your device.
- 02
Shape it
Start from Slowed + Reverb or Sped Up, or dial it in yourself. Flip between A (original) and B (processed) to check your changes.
- 03
Export
Render a 44.1 kHz stereo WAV at 16-bit, 24-bit or 32-bit float. The reverb tail rings out instead of getting chopped.
Worth knowing
Big changes can sound processed. Trust your ears.
Stretching or pitching far from the original can smear transients and add a slightly watery sound, especially on drums and below 0.7× or above 1.5×. Turning off "Keep pitch" usually sounds more natural for slowed and sped-up versions. Only release edits of songs you have the rights to.
Time-stretch and pitch-shift by Signalsmith Stretch (MIT). Reverb impulse responses are synthesized in-house.
Need it mixed?
Want more than a quick edit? Get it mixed.
If the song itself needs work, a proper mix gets the vocal, low end and space right before any edit.
