App Description
Remove vocals, split any song into stems, and change pitch or speed — all on your device, with no account and no upload. Up Tempo is a music practice tool and audio editor for singers, instrumentalists, transcribers, and producers. Slow down a solo to learn it. Drop a track's key to match your voice. Isolate the drums to practice along. Loop the hard bar until it clicks.
PRACTICE ANY SONG
• Slow down or speed up music in real time without changing pitch
• Transpose up or down by several octaves, with a preserve-formant option that keeps vocals natural
• Reverse playback for ear training and transcription
• Precise AB loop points on a pinch-to-zoom waveform
• Save loop points, effects, and settings per track and pick up where you left off
VOCAL REMOVER & STEM SEPARATION (Pro)
• Runs on your device — no account, no upload, works offline once models are installed
• Choose a fast 2-stem model (vocals / instrumental) or a higher-quality 4-stem model (vocals, drums, bass, other)
• Solo or mute individual stems in the mixer to build instant karaoke tracks or backing tracks
• Great for singers, guitarists, bassists, and drummers who want to play along with just the rhythm section
