How to Make a Slowed + Reverb or Nightcore Version of a Song
5 min read · Updated July 24, 2026
Slowed + reverb (dreamy, slower, spacious) and nightcore (faster, higher-pitched, energetic) are two of the most-shared audio edits on TikTok, YouTube and Instagram. They sound like a lot of production work, but both are simple speed-and-pitch transforms you can do in about a minute — including on tracks you made yourself in Suno.
What each style actually is
- Slowed + reverb — the song is slowed down (which also lowers the pitch) and a wash of reverb is added, giving that hazy, late-night feel.
- Nightcore — the song is sped up and pitched higher, making it brighter and more energetic. Classic for gaming and hype edits.
Make a slowed + reverb version
- Open the slowed + reverb maker and drop in your song.
- Dial in how much to slow it (around 80–90% speed is the sweet spot — too slow gets muddy).
- Set the reverb amount to taste, then export.
Make a nightcore version
- Open the nightcore maker and add your track.
- Bump the speed up (about 120–135% is the typical range).
- Export — the pitch rises with the speed automatically, which is the nightcore signature.
Want more control? Separate the two knobs
The presets above tie speed and pitch together the way each style expects. If you want to change speed without changing pitch (or vice versa), use the speed changer and pitch shifter independently. You can also layer extra space with the reverb tool on its own.

Frequently asked questions
How much should I slow a song for slowed + reverb?
Around 80–90% of the original speed usually sounds best. Below that it starts to sound muddy and the reverb gets overwhelming. Start at 85% and adjust to taste.
Does nightcore change the pitch too?
Yes — that's the point. Nightcore speeds the track up and lets the pitch rise with it, which gives the bright, chipmunk-adjacent energy. The nightcore maker does both in one step.
Can I do this to my own AI-generated song?
Absolutely. Any MP3 or WAV works, including tracks from Suno or other AI tools. Everything runs in your browser, so your unreleased audio never gets uploaded.
