TL;DR
of the models list (so a shortened version)04.08.26There's no single model always for everything. Usually it's a matter of testing a few models or even ensembling till you get the best results (also, be aware that sometimes your taste or listening environment determines how sensitive you're to certain artefacts of separation models and how passable the results are for you).
ACAPELLA (vocals)
- MVSEP BS-Roformer 124 bands becruily (fine-tune of the below, good mix of fullness and bleedless, premium only)
- MVSEP BS-Roformer 124 bands (premium only, the best SDR, more bleedless)
MVSep BS-PolarFormer 124 bands (the 2nd best)
- MVSep BS-Roformer 2025.07 (bleedless, and accuracy, muddy)
- Becruily Deux (fullness, but still a bit similar to the PolarFormer),
BS_RoFormer_mag (fullness with more bleedless; very noisy at quiet parts),
BS_Roformer_mag_v2 (worse SDR, bigger fullness, you might like it more),
- unwa BS-Roformer-Leap Xe (best metrics for public model, e.g. the non Xe more highs, less mids vs Deux)
- HyperACE voc v2 (bleedless, with more fullness),
- MVSEP BS-Roformer 124 bands becruily (good mix of fullness and bleedless, premium only, duality model with also dedicated instrumental stem, so not an inversion)
Deux (former perfect compromise of bleedless and fullness, also duality model)
bs_roformer_inst_hyperacev2 (fuller; doesn’t work with UVR)
(older but still might work)
