Mel-Roformer MVSEP drumsep models

 

1) 4 stems v2 (kick, snare, toms, cymbals) - “It gives the best metrics with a big gap for kick, snare and cymbals.” - ZFTurbo. The old v1 below was removed.

(metrics; only toms are worse SDR-wise vs previous SCNet Drumsep models below)

1) 4 stems v1 removed (kick, snare, toms, cymbals) - average SDR of hihat ride, crash is 11,52 (but in one stem) and so far it’s the best SDR out of all models (even vs the previous ensemble consisting of three MDX23C and SCNet models).

2) 6 stems (kick, snare, toms, hihat, ride, crash) - average SDR of hihat ride, crash is 8.18 (but from separated stems), while

The snare in 1) has the best SDR out of all available models.
Kick and toms are still the best SDR-wise in the previous 3x MDX23C and SCNet ensemble (new ensemble with these new Mel-Roformers so far)

 

- The new models “are very great for ride/crash/hh. And overall, they have the best metrics for almost all stems.” - ZFTurbo

Evaluations on new dataset (esp. check Log WMSE Results with “"bypass_filter" with torch_log_wms, ([good] at least for drums or anything rich in low frequency content)” - jarredou

 

Sometimes the newer jarredou’s drumsep 6 stems model below can serve to clean up “upper frequency range of snare hits” in the cymbals stems in “either MelRoFormer or SCNet-XL four-or-six stem DrumSep models” - Dyslexicon

“The core problem is that the main MVSep Drums model which is used by everything- including the Drumsep models- is not purely drums, it's mixed with other percussion which taints things.” - godzfire
