Real-Time On-Device Stem-Level Control Without AI Source Separation

• Original master playback with real-time stem-level control, on any device
• Higher quality and much lower hardware requirements than real-time AI source separation
• Legal compliance — no stems stored or distributed, no derivative works
• Content authentication — works only with the original master it was prepared for

Now licensing. We invite streaming services, record labels, karaoke platforms and music-tech companies to license the technology.
