Make nightcore and slowed + reverb online, free

Music Speed Studio is a free online nightcore maker and slowed + reverb studio. Upload any song and change its speed, pitch, reverb and bass boost right in your browser, then download the result as MP3 or WAV. There's nothing to install, no account to create, and your audio never gets uploaded anywhere — every effect is rendered on your own device.

Whether you want to turn a track into fast, upbeat nightcore or a slow, hazy slowed and reverb edit, the controls are the same simple sliders you'd find in a desktop audio editor — just faster and friendlier.
