## What is Up Tempo?

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 

EDIT & MIX 
• Trim music with millisecond precision; add fade in and fade out 
• Multi-track editor: layer, align, and mix your own tracks into new arrangements 
• Record vocals or instruments directly in the app (Pro) 
• Waveform visualisation with pinch-to-zoom for accurate edits 

STUDIO EFFECTS (Pro) 
• Equaliser, reverb, delay, compressor, noise gate
• High-pass filter, low-pass filter, bass cut, panning, centre/sides isolation 
• Creative effects: distortion (clip, saturate, crunch, overdrive), bit crusher, ring modulator 
• Chain effects and toggle them on or off in real time 

EXPORT & SHARE 
• Export to MP3, M4A (AAC) at 128, 256 or 320 kbps, or FLAC lossless 
• Edit title, artist, album, and album artist metadata before export 
• Share exported tracks to any app 
• Backup and restore your settings, markers, loop points 

FREE vs PRO 
Free includes pitch and tempo adjustment, looping (up to 6 markers), trim, fade, 2-track mixing, and export. Pro unlocks stem separation, vocal removal, recording, all studio effects, unlimited markers, and unlimited multi-track. One-time purchase, no subscription. 

Up Tempo supports most common audio formats including MP3, M4A, AAC, WAV, FLAC and OGG.

### 3/5 — Big problem

*2026-08-20, version 2.6.1*

There’s a bug in the system that if I increase the pitch on my music it decreases the quality of the audio and deafens some sounds like piano or high pitch drums. If this can be fixed then it’ll be back to its former glory.

### 5/5 — Javier

### 5/5 — Bug

*2026-07-21, version 2.6.0*

I would usually rate this app 5 stars because I have been using this app for years now but this bug has came the most recent update (being the one from last month) when I would use my headphones to go to a previous song on my playlist it would just replay the current song i’m on and only let me play the next song. It used to be where i would press and hold the previous button on the headphones twice and it would play the previous song but now as a temporary fix i have to use shuffle mode. Please try to fix this as soon as possible.
