How it works

  3. Fine-tune with the Speed and Reverb sliders.
  4. Download a WAV file that works in any app or DAW.

You also get MP3 downloads at 320 kbps and extra effects: bass boost, lo-fi, vinyl crackle and 8D audio. Try the effects for free, download them with Pro. One-time €4.99.

Can I use any song?

Only use this tool on music you're allowed to edit: your own tracks or beats with a licence that allows edits and releases. Uploading a slowed or sped up version of someone else's song without permission can infringe copyright and lead to claims.
