Stem Splitter

Split any song into six stems.
On your device.

Vocals, drums, bass, guitar, piano and everything else — pulled apart on your iPhone or iPad. No account, no upload, no waiting on a server. Put the phone in aeroplane mode and it still works.

Mute the singer, keep the band

Every stem gets its own fader, mute and solo. Drop the vocal for a backing track, solo it for an acapella, pull the bass out to learn the line.

Learn the song, not just the recording

Key, tempo and chord changes worked out automatically, with guitar and piano diagrams that follow the music bar by bar.

Practise at your own pace

Slow to 50% without changing pitch. Transpose ±12 semitones. Loop the four bars you keep fluffing until they stick.

A metronome that knows the song

The click locks to the detected beat, not a number you typed. Time signature, subdivisions, count-in and bar alignment.

Your music stays yours

The separation model runs locally using Apple silicon. There is no server, no sign-up and no tracking, and the app collects no data of any kind. See the privacy policy for the detail.
