Slowed & Reverb Generator
Make slowed + reverb, super slowed, or nightcore versions of any track. Pitch follows speed like vinyl, a convolution reverb adds the space, and the result downloads as clean WAV. Everything runs in your browser.

What Is Slowed + Reverb?
Slowed + reverb is the modern descendant of Houston's chopped and screwed sound from the 1990s: play the record noticeably slower so the pitch drops with it, then drench the result in space. The style resurfaced through phonk and exploded on YouTube and TikTok, where slowed versions of pop and rap songs routinely outperform the originals. The recipe is precise enough to automate, which is what this tool does: a rate change with pitch following (like vinyl dragged below its RPM) plus a long, dark reverb tail. Nightcore is the same trick pointed the other way, born from the Norwegian duo of the same name: speed the song up 20 to 30 percent, let the voice go bright and high, keep it nearly dry.
The Presets
- Slowed + Reverb: 85 percent speed, moderate hall reverb. The classic sound
- Super Slowed: 75 percent speed with a bigger wash for the deep, dreamy version
- Nightcore: 127 percent speed, pitch up, nearly dry
- Custom: speed from 50 to 150 percent and reverb from dry to drenched
Tips for an Edit That Sounds Deliberate
- Songs with clear vocals and space in the arrangement slow down best; dense walls of sound turn to mud below about 80 percent
- If the slowed vocal sounds too deep, try 90 percent instead of 85; the aesthetic survives, the voice stays human
- More reverb is not automatically moodier: past roughly 45 percent wet the transients smear and the groove dies
- For nightcore, source songs in the 100 to 122 BPM range land in the sweet spot once sped up
- Check where your edit landed with the key and BPM finder; a slowed edit drops roughly 3 semitones at 85 percent, which changes which tracks it mixes with
Slowed Edits vs Proper Tempo Changes
This tool deliberately lets pitch drop or rise with speed, because that wobble is the aesthetic. When you need a track at a different tempo but the same key (for mixing or mashups), use the Key & BPM Changer, which detects the track's BPM and time-stretches to an exact target without touching pitch. To check what key and tempo your edit landed on, run it through the Song Key & BPM Finder.
