1. We created independent synthetic dataset to compare different music source separation algorithms. We published dataset here as well as automatic judging test system. Also leaderboard of best algorithms is available.
2. New MDX-B UVR vocal model was added. It's latest reelease from UVR Team. You have ability to choose it during selecting MDX-B algorithm in form.
3. New models from Ultimate Vocal Remover based on demucs3 architecture were added. It's available by name UVR Demucs in algorithm list.

Quality metrics for algorithms including UVD Demucs can be found here.
