Music Speed Studio: the nightcore and slowed + reverb app

Music Speed Studio is a free nightcore maker and slowed + reverb app for iPhone and Android. Pick a track from your device, change its speed, pitch, reverb and bass boost with live sliders, and save the finished edit back to your phone. There is no account to create and no paywall in the way.

Whether you want fast, high-energy nightcore or a slow, hazy slowed and reverb edit, the controls are the same ones you would find in a desktop audio editor — only faster, friendlier, and in your pocket.

One app, every speed & pitch edit

Nightcore maker

Speed a song up and pitch it higher at the same time to get that classic, high-energy nightcore sound in seconds.

Slowed + reverb maker

Slow a track down and drench it in reverb for the dreamy, atmospheric slowed and reverb style everyone's sharing.

Song speed changer

Speed up or slow down any song with a precise speed slider — from a gentle 0.7× chill to a fast 1.5× rush.

Pitch & bass control

Shift the pitch of your song and add bass boost to make it hit harder, all in real time as you listen.

How to make a nightcore or slowed + reverb song

Install the app

Download Music Speed Studio free from the App Store or Google Play — it is a few megabytes and needs no account.

Pick a track

Choose an MP3, WAV or MP4 already on your device. Your audio is processed on the phone itself, so nothing is uploaded.

Set speed, pitch, reverb & bass

Raise the speed for a nightcore effect or lower it for a slowed feel — pitch follows the speed, exactly like the original nightcore technique — then add reverb and bass boost.

Save & share

Export your edit in high quality and save it straight to your device, ready to share anywhere.
