Four stems. Surgical precision.

Upload any track and watch it decompose into its fundamental layers — each one studio-quality, ready for remix, practice, or production.

Vocals Stem

Crystal-clear vocal isolation. Hear every breath, every nuance, every harmonic — completely separated from the mix.

Drums Stem

Every kick, snare, and hi-hat, surgically extracted. Perfect for sampling, drum replacement, or rhythm analysis.

Bass Stem

The low-end foundation, isolated with weight and warmth intact. Study the groove or build your own on top.
