About this app

A music editor, audio speed changer, recorder, and pitch shifting app designed by musicians. Up Tempo now also includes stem separation so you can easily remove vocals, guitars, or drums for instrument practice or creating backing tracks.

Smoothly change the playback speed and pitch of audio files. Whether you're a vocalist needing to adjust a song's key, a musician practicing a challenging piece, or a podcaster tweaking audio speed, Up Tempo is your go-to tool.

Up Tempo’s waveform view lets you quickly see where you are and skip to a specific point in a song. Stuck on a particular section? Precisely set points to loop between. Need more accuracy? Pinch and zoom to get a more detailed waveform view. Want to remove parts of your track? You can use the waveform view to trim your track or add fade-in and fade-out.

When you have finished a session you can save your loop points and pitch/tempo settings to use another time. You can also export your adjusted song and share with others.

Up Tempo is more than just a pitch shifter and vocal remover app. It can also be used as a music looper and general audio editor, for changing the talking speed on voice notes and podcasts, or for making nightcore and multi-tracks. The pro version of the app has lots of advanced editing features including equaliser, reverb, and delay.

- Stem Separation: Isolate vocals, guitars, drums, and other instruments for practice, remixing, or creating karaoke tracks. Remove vocals to sing along or isolate your instrument to practice with the band.

Ratings and reviews

Up Tempo is a great app for creatively adjusting pitch, speed, and EQ on your favorite tracks. It’s fun, easy to use, and lets you make something truly unique. A cool feature to consider adding would be a Multi Shifter to also change the main vocals—like simulating background singers in different pitches. That would take it to the next level! Still, solid 5 stars from me!

I downloaded this app quite some time ago, and I never thought much of it once I actually started to mess around with its free features, including transposing, reverse play, and tempo change. It keeps me VERY entertained with the fact that I can increase or decrease the pitch and hear the faint details more clearly in instruments. You can also analyze your own downloaded music:)

Best app I have ever used for the past 3 or so years! I personally love being able to listen to music while it being easily accessible and easy to edit or change. However, I have this one complaint, sometimes when you listen to music, the music goes choppy or laggy, and it's often upsetting or distrupting when you are listening to music and vibing. This usually happens when you have the audio at a super low tempo and pitch, which is kind of irritating. I hope this can be fixed! Love the app tho!
