Stem Splitter & Tuning

A track split stem by stem — and the tuning set right.

track: 5 credits + 10 per minute · video or film: 8 credits + 12 per minute

Vocals, drums, bass, guitar, piano: each element isolates, and what's left rebuilds exactly. Tuning resets (442 → 440 Hz), the key transposes by semitones, tempo untouched. For a video or a film, the sound splits into voice, music and effects — music out, or voice out for a karaoke or a dub — and the picture doesn't move.

FAQ

Which elements can be isolated?

On a track: vocals, drums, bass, guitar, piano, and the rest of the mix — the tool first detects what plays, then each element checks on or off. On a video or a film: voice, music and effects.

What is the tuning reset for?

Some recordings sit at 442 Hz: playing along with a 440 instrument gets painful. The reset fixes that — and transposition changes the key without changing the tempo.

Does it work on every video?

Best with distinct elements. Splitting music from effects is trickier, and a voice caught in a reverberant room can leave traces — a physical limit, not a setting. Out comes an MP4 with the picture intact and the sound rebuilt without what was removed.
