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.

How this page is made
Tool pages are built from reusable page logic, internal DJ reference data, and visible on-page calculations. Programmatic reference pages are generated from structured data rather than hand-written one by one.

BPM, key, and genre labels can vary by edit, remaster, detection engine, and DJ software. Use these pages as a practical mixing reference, then verify important tracks in your own library.

Frequently Asked Questions

Drop the song into the tool above, pick the Slowed + Reverb preset (85 percent speed with a hall-style reverb), and press Create edit. The processed version renders in your browser in seconds and downloads as WAV. Use the Custom preset if you want your own speed and reverb amounts.
Same flow, but choose the Nightcore preset: it speeds the track to about 127 percent with pitch rising along, which is the classic nightcore sound, plus a touch of reverb. If you want a different amount of chipmunk, switch to Custom and set the speed slider anywhere up to 150 percent.
Because that is the sound. Slowed + reverb and nightcore edits are defined by pitch following speed, like a record played at the wrong RPM. If you want to change tempo while keeping the original pitch, use our Key & BPM Changer instead, which time-stretches without pitch shift.
No and no. Everything renders inside your browser, the file never leaves your device, and the WAV you download is clean, full quality, and unlimited. There is no account and no daily cap.
The tool puts no restrictions on the output, but the music's copyright still belongs to its rights holders.
