Quick answer

Updated

To make a song slowed and reverb, lower its playback speed (usually to 80–90%) — which also lowers the pitch — and add a long, washy reverb. The tool above does both in your browser: load an MP3, WAV, M4A or OGG file, choose Slowed + reverb (85% speed, 45% reverb), Extra slowed, Sped up or Nightcore (125%), adjust the sliders while it plays, then download a WAV. Processing happens on your device with Web Audio — the file is never uploaded. Use it on music you have the rights to; for an original track to slow down, Kenerate's Music Studio can make one.

Tips

Better slowed + reverb

What sounds good — and what to avoid.

  • Songs with airy vocals and pads slow down beautifully; busy drums get muddy.
  • Start at 85% — below 75% vocals can sound unnatural.
  • Nightcore works best on energetic tracks with clear vocals.
  • Long files take longer to render on phones — trim first if needed.
  • Only upload music you have the rights to share.

In depth

Slowed + Reverb Maker, explained

What works, what to avoid, and how the pieces fit.

Where slowed + reverb comes from

Slowed-and-reverb edits grew out of chopped-and-screwed hip-hop and later took over YouTube and TikTok: slower tempo, lower pitch and heavy reverb give songs a dreamy, nostalgic feel. Nightcore is the opposite — faster and higher.

How the tool works

Under the hood:

  • Speed — changes playback rate, so pitch follows (like a record).
  • Reverb — a convolution reverb with a generated 3-second tail.
  • Export — rendered offline, sample-accurate, as a WAV.

FAQ

Slowed + Reverb Maker questions

7 questions

Still stuck?

A real person answers — usually within a day.

01

How do I make a song slowed and reverb?

Load the file into the tool above, choose Slowed + reverb (about 85% speed with a long reverb), adjust to taste, and download the WAV.

02

Is the slowed reverb maker free?

Yes — it runs in your browser with no sign-up, and the WAV download is free.

03

Is my file uploaded?

No. Everything happens on your device with the Web Audio API; the file never leaves your browser.

04

How do I make nightcore?

Choose the Nightcore preset (about 125% speed) — speeding up raises the pitch, which is the nightcore sound.

05

Why does slowing down lower the pitch?

The tool changes playback speed, like a turntable, so pitch moves with speed — that's the characteristic slowed sound.

06

What formats work?

Most MP3, WAV, M4A and OGG files; the download is a WAV.

07

Can I upload slowed versions of other artists' songs?

Only if you have the rights. For something you can share freely, make an original track in the Music Studio and slow that down.
