Up Tempo: Pitch, Speed Changer 4+

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.
