Debleeding/cleaning vocals/instrumentals/inverts
1) For constant vocal shells/buzzing of Roformer instrumental models (don't confuse with residues)
- Phase fixer (for instrumentals - uses phase of inst vocal model result on inst model result)
- MVSep PolarFormer (for “pulling out some of the vocal noise leftover by the BS-Rofo high fullness models, without muddying the sound” - CC Karaoke).
- Gabox Mel denoise/debleed model (when used on the mixture) | yaml | Colab | SESA Colab v3 - for fullness models (tested on v5n) - it can't remove the vocal residues
- Lew Apollo Universal on hi-hat and snare from drumsep 6 stems model by jarredou from drums model from e.g. flowersv10 inst model (I've noticed that most of the residual "Fuzz" is usually trapped in the snare or cymbals. - CC Karaoke)
- minimax-music3-latent-refiner - “does a pretty good job with cleaning up outputs from gabox v10 flowers melband roformer model” - pitbulldale305. Currently there seem to be some problems with processing audio longer than 30 seconds. Coding some chunking with overlapping would make it easier to use.
- Weighting manually Drumsep model results with SAM-Audio-prompted drumsep in L/R because SAM is mono (to get drumsep from drums too, but also with SAM) - to get cleaner results of snare and hi-hat (“ I lower the original snare/HH drum stem by maybe 5 or 6dB, and the SAM drum stem by 1 or 2dB... basically the idea is to make sure the volume of the drums in the mix is about the same as it was originally; but lowering out the sound of the noise while keeping as much of the original sound as possible.” more)
- Denoise models (e.g. Aufr33’s Mel is less aggressive and effective than phase fixer, UVR Denoise more aggressive and destructive, you can try out Mel on mixture first)
- DEBLEED-MelBand-Roformer (by unwa/97chris) model | yaml | Colab
(it can work with e.g. inst v1 and its noise, or with v1e, or even MVSEP Karaoke BS-Roformer instrumental stem for “very clean and full” result. Also, sometimes the debleed model can remove some bleed also after using phase fixer)
2) For crossbleeding/residues/leftovers or cleaning inverts
- Mel-Roformer invert-clean by becruily | Colab | MVSEP (model dedicated for cleaning acapella inverts [so when you use e.g. official instrumental with mixture inverted in order to get vocals and it gives some residues].
vs the gilliaan’s model below “In my testing the becruily one works better” - dynamic64, but sometimes the first might work better (depends on what trade-off in sound you want to accept).
“Most regular models don't do the job (...) It removes peaks/pops, clicks, instrumental residue (...)
I didn't focus on things like fullness” - becruily
“Cool model, it's a little muddy on loud/clipped vocals but otherwise it works great (...)
it does work well for leftovers” - gabiigh
“It works great (...) the result is fantastic!” - billieoconnell.
“This has to be [becruily's] best model ever, so useful, sounds so great too... I'm shocked it truly is so good”
Consider using it with overlap 4 - gilliaan
“The invert clean still removes vocals normally, you can use it with normal songs but deux will do a better job for that.
It specializes in cleaning up stubborn invert artifacts where deux might fail to do so” - becruily)
- Colab auto-cleaning by billieoconnell - uses Deux result acapella using the invert-clean model above.
“Most of the acapellas come out fine, but in some, when I run them through the AI, there's a drop in the bass where the drums hit, making the vocals sound like they're on a bass drum. (...) when I run it through a model on other websites or similar platforms, the result is great.”
bsroformer_cleaninvert by gilliaan | yaml | Colab | MVSEP
A “model specifically for cleaning up residuals from mp3 inverts specifically aimed to extract vocals cleanly, (...) (Thx becruily for the idea)”
“Works best if you preprocessed the inverted acapella using big beta 5e, then remove the residuals using my model.”
For other genres than EDM/electropop:
BS PolarFormer, Anvuew V2 and 6x or Deux (billieoconnell, gilliaan).
“When you invert an official instrumental against a song, lossy audio can leave behind that weird pixelly/smeared artifacting from the compression. This model is trained to remove those residuals and also clean up the crunch/clipping that can come with them, bleedless model. Finetune of [the] Revive [model].
It's basically meant to make mp3-based inversions sound much cleaner and closer to what you'd get from the original Acapella source.”
- introC python script to get rid of vocal leakage in v1e+ model (not tested for others)
- MVSEP BS-Roformer 2025.07 (e.g. “after making the deux hyperace ensemble ensemble, at least in my cases, works good to remove any small residues that are left in quieter/airy parts of songs” - arxynr)
- VR’s HP2-4BAND-3090_4band_arch-500m_1 in HV Colab a.k.a. 9_HP2-UVR in UVR, aggressiveness 1.0 on MVSEP/Colab, 100 in UVR (works for vocal residues from inst Roformers, “can take some vocals residues that even those bleed suppressor models can't (...) still works somehow for cleaning that even BS-Roformer 2025.07 couldn't”, helps with some vocal reverb and some choir vocals and old anime songs and regular nu metal songs - mohammedmehditber)
- MVSEP Choir (same as with 9_HP2, but esp. for choir residues - mohammedmehditber)
- UVR Denoise Standard
- UVR Denoise model with 0.1-0.2 aggressiveness (for debleeding vocals from instruments)
- UVR-MDX-NET Crowd HQ 1 (“sometimes fixes screaming Roformers can't, but it has more muddiness and bleeding in general”)
- Roformers: Mel 2024.10 on MVSEP a.k.a. Bas Curtiz FT (for vocals debleeding)
- Or earlier Kim Mel-Roformer model (for vocals; if other model was prev. used)
- Unwa inst v1 (to clean-up vocals from Mel 2024.10 model)
- unwa’s inst v1/e/2 (for OG instrumentals with bleeding [better than Dango for it])
- unwa big beta 5 (“my go-to clean-up artifacts model after phase inverting master + official instrumental”)
- Unwa BS Revive 3e (although Revive 2 has bigger bleedless metric)
- voc_fv6 (for vocal inverts - ezequielcasas)
- Mel avuew’s v2 de-reverb or unwa’s BS Large, MDX-Net HQ_5
(“great for cleaning acapellas from bits of instrumentals”)
- syftbeta 5 on x-minus.pro (might be still available with this link for premium, and for free)
- Gabox FV7
- Ensemble of BSRoformer-Viperx1297, Unwa BSRoformer-LargeV1, unwa_ft2_bleedless, mel_band_roformer_vocals_becruily, Gabox voc_fv4 on Average/Average
(good for cleaning inverts - AG89)
- Ensemble of big beta6x, revive2, unwa ft2 bleedless
(for cleaning instrumental inverts - AG89)
- Or just experiment with other models with the highest bleedless metric (instrumental | vocals)
- SFX models are more aggressive than vocal models (not tested for this purpose yet)
- yxlllc’s harmonic noise separation VR model (“Very good at further removing the noise from a dereverbed vocal, yet it is mono. (...) It did have two channels on export but both of them have audible information except one has only some noise that can be easily removed, then mix the other channel up to stereo” - mohammedmehditber. Maybe attached CLI code will have better mono model handling.
Can be used in UVR: rename “model” to some model name, and pt extension to pth, then use Install model option and set config settings to: VR 5.1, 32/128, 1band_sr44100_hl512)
- Sam Audio by Meta - Iirc, on mid side processed files, it got rid of some noise and knocking when separating SFX and instrumental with a prompt “music” and later with a prompt “knocking” on the result file “and selected the part at 0:35 and 0:36 for span prompting” - nicov_na
- RX10/+ De-bleed feature for instrumentals (video)
- Acon Digital Acoustica
(older methods)
- Gabox Mel denoise/debleed model | yaml | Colab | SESA Colab v3 - for noise from fullness models (tested on v5n) - it can't remove the vocal residues
- Mel denoise (iirc Aufr33’s) - that model “removed some of the faint vocals that even the bleed suppressor didn't manage to filter out” before”. Try out denoising on a mixture first, then use the model.
- (for saxophone bleeding) ~“1. Take the original song in FLAC or WAV 2. Use MVSEP Saxophone 3. Take the other stem from it - there should be everything else and most of the sax should be gone (for me, there was a small part left) 4. Use Unwa Big Beta 5 on it (so Other-> uvronline/xminus/Colab Unwa Big Beta 5) - then vocals should be very clean no sax bleeding” cali_tay98
- (“In case there's any wind instruments that could potentially bleed into the vocals”)
MVSep Wind
- (when “models don't pick up the noise)
gently bring back a bit of the original music/instrumental on the inverted track and use AI again.
By gently, I mean no more than 6 dB“ - becruily
- (“If your result have "vocal chops" left in the instrumental separation and no models could remove them completely)
then it's likely MDX HQ_5 or VitLarge23 v2 will fix it” dca
- Acon Digital DeBleed:Drums “it's just an advanced gate. It doesn't remove bleed when it's overlapping the wanted audio (we can still hear hihat/cymbals on snare with the plugin enabled in their demo)” - jaredou.
- Audio-Bleeding-Removal - by its-rajesh
- Try out some L/R inverting, try out to separate multiple times to get rid of some vocal pop-ins like this (fix for ~"ah ha hah ah" vocal residues)
- Accentize VoiceGate and Acon Extract Dialogue
(to debleed dialogues from SFX models)
Older de-bleeding models
- Ripple (defunct) “AWESOME to use after inverting songs with the official instrumental”
Instrumentals can be also further cleaned with Ripple, and then with Bandlab Splitter
(Roformer models may potentially replace Ripple models in that matter now)
- Top ensemble in UVR5 (starting from point 0d)
- GSEP - very minor difference between both for cleaning vocals (maybe GSEP is better by a pinch).
You can try separating e.g. vocal result double using different settings (e.g. voc_ft>kim vocal 2)
- MVSEP 11.50 Ensemble (the least amount of bleeding in inst. separations at least)
- MDX23 jarredou's fork Colab (maybe this version at first)
- use voc_ft model on the result you got (so separate twice if you already used that model)
Cleaning inverts means - cleaning up residues - e.g. left by the instrumental after an imperfect phase cancellation, e.g. when audio is lossy, or maybe even not from the same mixing session
