Datuva by Zovda · Training data

Stems that stay aligned on the timeline.

Instrument-level stems — drums, electric guitar, keys and synth, loops, vocals, and bass — delivered as 44.1 kHz/24-bit WAV. Every stem in a track shares one timeline, so separation, mix analysis, and generation work on the same clock.

FAQ

Before you request a collection.

Is every track 41 stems?

No. The 41-stem set is one reference track; other tracks ship with different stem counts.

Can we take one instrument family?

Yes. Stems are organized by family and by track, so a subset can be delivered first.

Can stems be re-exported at another rate?

Format changes can be scoped before production.
