FAQ
How do I make a slowed and reverb song?
Drop the song here, keep the Slowed + reverb preset (0.80× speed, 35% reverb) or adjust it, press Preview, then click Make slowed + reverb and download MP3 or WAV.
What speed is best for slowed + reverb?
Most edits use 0.75–0.85×. Extra slowed is around 0.70×; Subtle is about 0.88×.
Can I slow a song down without changing the pitch?
Not here: the classic slowed sound comes from the pitch dropping with the speed, which is what this tool does. For pitch-only changes, use the voice changer's pitch control.
Is my song uploaded?
No. Decoding, effects and MP3 encoding all run in your browser.
Can I post it on TikTok or YouTube?
Only if you have the rights to the song. Slowing a track doesn't change its copyright; platforms may mute or block it.
Does it work on my phone?
Yes in modern mobile browsers. Long songs take longer to render on phones.
What about nightcore?
Nightcore is the opposite (faster and higher). This tool goes from 0.60× to 1.00×; for reverb on the original speed, use the Reverb only preset.
