Other services (multi-purpose)
- Ripple (no longer works; since BS-Roformer models release it might be obsolete; it's very good at recognizing what is vocals and what's not and tends to not bleed instrumental into vocal stem; very good if not the best solutions for vocals)
- music.ai (paid; presumably in-house BS-Roformer models)
“almost the same as my cleaned up work (...) It seems to get the instrument bleed out quite well”)
“Beware, I've experienced some very weird phase issues with music.ai. I use it for bass, but vocals are too filtered/denoised IMO, and you can't choose to not filter it all so heavily. ” - Sam Hocking
- https://myxt.com/ (paid; uses Audioshake)
- moises.ai (paid; uses in-house BS-Roformer models, sometimes better results than the one on MVSEP)
- ZFTurbo’s Bandit Plus (MVSEP)
Other decent single UVR models
- Main (427) or 406, 340, MDXNET_2_9682 - all available in UVR5, some appear in download center after entering VIP code)
- or also instrumental models: Kim Inst and HQ_3 (via applied inversion automatically)
Other models
- ZFTurbo's Demucs v4 vocals 2023 (on MVSEP, unavailable in Colab, good when everything else fails)
- MDX23 Colab fork 2.1 / 2.2 (this might be slow) / 2.3 / 2.4 / 2.5 (it's generally better than UVR ensembles SDR-wise, but it's not available in UVR5) (MDX23 Colab is good also for instrumentals and 4 stems, very clean, sometimes more vocal residues in specific places vs single MDX-UVR inst3/Kim inst/HQ models, but it sounds better in overall, especially the Colab modification/fork with fixes made by jarredou)
- HQ_3 (inverted result giving vocals from instrumental in 2nd stem) - more instrumental residues than e.g. Kim Vocal 2, but no 17.7 cutoff)
- Narrowband MDX23C_D1581 “Leaves too much instrumental bleeding / non-vocal sounds behind the vocals. Formants are less refined than on any of the top vocal models (Voc FT, Kim 1, Kim 2 and MDX23C-InstVoc HQ).”
- Kavas' methods for HQ vocals:
Ensemble (Max/Max) - Low pass filter (brickwall) at 2k:
- MDX23C
- Voc FT
Voc FT - High Pass Filter (brickwall) at 2k
(“Sometimes it leaves some synth bleeding in the mids" then try out min/min)
Or:
Multiband EQ split at 2kHz with a low & high pass brickwall filter with:
-MDX23C-InstVoc from 0 to 2kHz and:
-Voc_FT from 2kHz onwards
(InstVoc gives fuller mids, but leaves transients from hats in the high end, whereas Voc ft lacks the mids, but gets rid of most transients. Combine the best of both for optimal results.)
- Any top ensemble or AI appearing on MVSEP leaderboard (but it depends, - sometimes it can be better for instrumental, sometimes vocals
Ensembles are resource consuming, no cutoff if one model is fullband and the other is narrowband. Random ensembles can result in more vocal or instrumental residues, as mentioned above.
Models not exclusive for MVSEP are all available in UVR5 GUI, or optionally you can separate MDX models in Colab and perform manual ensemble in UVR5 (no GPU or fast CPU required for this task) or use manual ensemble in Colab [may not work anymore]) or also in DAW by importing all the stems together and decreasing volume (you might want to turn on limiter on the sum).
