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