Any other stem/instrument/sample if not listed above

- Zero Shot Audio Source Separation

- Bytedance-USS (might be worse for instruments, but better for SFX)

- Dango.ai custom stem separation (paid, free 10 seconds preview)

- Audiosep (separate everything you describe; Colab has unpickling issue)

- Spectral removers (software or VST):

Quick Quack MashTactic (VST), Peel (VST, they say it’s worse alternative of MT), Bitwig (DAW), RipX (app), iZotope Iris (VST/app), SpectraLayers (app, “Problem with RX [Editor's spectral editing] is it doesn't support working in layers non-destructively.”), R-Mix (old 32 bit 2010 Sonar plugin), free ISSE (app, showcase), FactorSynth, Zplane Copycat "but MashTactic also has a dynamics parameter that is really useful (you can isolate attack from longer sounds, or the opposite, coupled with the stereo placement and EQ isolation)"

RipX is “not as good as UVR5 for actual separation, but RipX is very good if you need to edit what's already separated more musically. SpectraLayers is a nicer spectral editor, RipX spectral editor is not as usable”

 

Consecutive multi-AI separation for not listed instruments

- Extract all other instruments "one by one" using other models in the chain (e.g. remove vocals with voc_ft or now e.g. inst Mel Kim derivative, use what's left to remove drums/bass with htdemucs_ft/MDX23/MVSEP ensemble, use what's left to remove guitars/piano with GSEP/demucs_6s or now any better purpose model, then use what's left to remove e.g. wind instruments (if present) with UVR wind model, or any any other purpose model applicable, even SFX, till you're left with the instrument of your choice, or as few instruments, as possible, for potentially easier work with spectral editor listed above)

 

- Drumsep - “Using DrumSep on melodic stems can help separate instruments easier if you plan on sampling/editing them, but they are separated based on range rather than actual instrument. Low instruments will often be on the kick/tom stems, mid instruments will be on snare and/or tom, and higher instruments will be on the cymbals.”
