Frequently asked questions

  • Choose the song, set Key to the number of semitones up or down (+2 is a whole step up, -12 an octave down), keep Tempo at 100% and press Change. The speed stays the same.
  • Pick Sped up or Nightcore. Both play the song faster, which raises the pitch too, like speeding up a record; nightcore is a little faster.
  • Pick Slowed + reverb: the song plays at 80% speed with a lower pitch and a big room reverb, the sound popular on TikTok.
  • No. The song is processed in your browser and never leaves your device.
