Slowed + reverb maker

Slow a song down or speed it up, drench it in reverb, and hear every change live. Save it as an MP3 for TikTok, Reels or Shorts.

The effects run on your device. Saving as MP3 sends the finished track to our server to compress it, and it's deleted as soon as the download is sent.

How to make a slowed + reverb song

  1. Choose a song from your phone or computer. Videos work too.
  2. Tap Slowed + reverb, or move the Speed and Reverb sliders until it sounds right. Press play to hear it change as you go.
  3. Press Save my version to download it as an MP3, then add it to your TikTok, Reel, Short or playlist.

Questions

Why does the pitch change when I change the speed?

That's the slowed and sped up sound. Like a record played at the wrong speed, slowing a song down makes it deeper and speeding it up makes it higher. It's what gives these edits their mood.

Does it work on iPhone and Android?

Yes. It runs in Safari, Chrome and other modern browsers on phones, tablets and computers, with nothing to install. If you don't hear anything on an iPhone, check that the silent switch is off.

Can I post the result on TikTok or Instagram?

The tool is free to use, but the song still belongs to whoever made it. Edits of popular songs are common on social media, though platforms may mute or remove them if the owner objects.

Is it free?

Yes, with no account and no watermark.
