Master the tempo in 3 simple steps

Make practice easier or test your skills with the AI Audio Speed Changer.

Upload a song

Import your track into the Moises App — desktop, web, mobile, or iPad version. It can be a file from your library or from a public URL.

Tap to adjust the bpm

Click the metronome symbol at the top and use the (+) and (–) controls to change audio speed, hitting reset to revert to the original tempo. As a Free user, you can adjust bpm up to +10 or as low as –10 bpm. Premium and Pro users, however, have no bpm limits when changing the speed.

You can always turn on the AI-generated click track for a more steady rhythm — or just procede metronome-free with the new speed.
