Questions
---------

How do I change the key of a song?

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.

 How do I make a sped up or nightcore version?

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.

 How do I make a slowed + reverb version?

Pick Slowed + reverb: the song plays at 80% speed with a lower pitch and a big room reverb, the sound popular on TikTok.

 Is my audio uploaded?

No. The song is processed in your browser and never leaves your device.

 How many songs can I change?

Free accounts get 20 runs a day. Making the same version of the same file again doesn't count.
