Slow Down a Song

Slow down a song right in your browser. You can keep the original pitch for practicing, or let the pitch drop with the speed for the deeper slowed-edit sound. One toggle switches between the two.

How the Preserve pitch toggle works

Everything comes down to the Preserve pitch switch in the Speed panel. With it on, the song holds its original key no matter how far you pull the slider down. A solo at 60% speed is still in the same key, and a vocal still sits in the singer's register. With it off, pitch falls along with the tempo, so the whole track turns deeper and thicker. Which one you want depends on whether you're practicing or just going for the sound.

Using it to practice

This page opens with the slowed + reverb preset already on. If you're here to practice, strip it back first: pull the reverb wet slider to zero, switch Preserve pitch on, then set your speed. That leaves a clean, in-key slowdown of the original recording, with no echo covering up the details you're trying to hear.

You can work out a solo phrase by phrase without transposing in your head, or run choreography at a tempo your feet can actually hit and inch the slider back toward full speed as the counts settle in. If you slow the song down enough, even the fastest rap verse becomes something you can transcribe one line at a time. Singers get a bonus: the semitone pitch control can shift the whole track into your range while you rehearse.

For the slowed and reverb sound

If you just want the slowed-edit sound (around 80% speed, pitch dropping with it, reverb around every hit), you don't need to change anything. The preset this page starts on is already that sound. From there, set how wet the reverb sits and try out rooms from a tight drum room up to a cathedral. For more on the effect itself, check out the slowed and reverb generator.

How to slow down a song

  1. Drop a file. The song starts playing right away. Processing happens on your machine, so there's no upload step at all.
  2. Choose your settings. Turn Preserve pitch on and set reverb to zero for practice, or leave the preset alone for the slowed-edit sound.
  3. Find the speed. Drag the slider while the song plays (anywhere from 25% to 200%) until it sits where you need it.
  4. Download it. You get a clean WAV bounce of exactly what you dialed in. It's free and the file has no watermark.

Frequently asked questions

Can I slow down a song without changing the pitch?

Yes, just turn on Preserve pitch in the Speed panel. The track keeps its original key at any speed, so chords, vocals, and melodies stay exactly where you expect them. If you leave the toggle off, pitch drops with the tempo instead, which is the deep slowed-edit sound.

What speed is best for practicing along?

There's no single right answer. Drop to whatever speed lets you play, dance, or sing the passage cleanly (for genuinely hard material that often means somewhere around 50 to 75%), then raise it a little at a time as it locks in. The slider runs from 25% to 200% in 1% steps, so you can work your way back up as gradually as you like.

Why does the song sound deeper when I slow it down?

With Preserve pitch off, tempo and pitch fall together, like a record slowing down. Every voice and instrument lands lower and heavier, which is exactly the effect slowed edits are built on. However, if you want the song slower but not deeper, that's what the toggle is for.

Can I keep the slowed version for later?

Yes. Download bounces your exact settings to WAV, so the practice copy you make today sounds identical next month. Since the file is saved to your device, it does not depend on this site or your connection. It accepts mp3, wav, flac, m4a, ogg, and aac files, and nothing is uploaded at any point.
