Free Online Slow Downer

Slow Down Any Song
Without Changing the Pitch

Drop a song to half speed and it stays in the same key — no chipmunk effect, no detuning. Loop the two bars you keep missing, and unlike any other slow downer, mute your own instrument and practise against the rest of the band.

Pitch Stays Put

Proper time-stretching, not a slowed-down tape. 50% to 100% speed, and the song never leaves its key — what you practise is what you'll play.

Loop the Hard Part

Drag across the waveform to loop a riff, a fill or a whole section. Stay on it at 70% until it's clean, then bring the tempo back up.

Mute Your Instrument

This is the part no other slow downer does: the song is split into six stems, so you can silence the guitar, bass, drums or piano — and take its place.

How it works

Step 1

Drop in a song

MP3, WAV, FLAC or M4A — anything you bounced, bought or recorded.

Step 2

Set the speed

Pull the tempo down to 75% or 50%. The pitch doesn't move.

Step 3

Play along

Loop the tricky section, mute your part if you want, and practise until it's yours.

Frequently asked questions

Does slowing down change the pitch?

No. The tempo change uses time-stretching, so a song at 75% speed stays in exactly the same key. There is none of the pitch drop you get from slowing a record or a tape.

How slow can I go?

Down to 50% — half speed. That's slow enough to hear every note of most solos while the audio still sounds like music rather than a smear.

What's different from other slow downers?

The separation. Classic tools like Amazing Slow Downer slow the whole mix. Here the song is split into vocals, drums, bass, guitar and piano first — so you can slow it down and mute or solo any part while you practise.
