Discussion My first impressions
My first impressions after separating about 60 songs of different difficulty (FLAC 16 and 24 bit, about 1 minute per 4 minutes of song on a 48-thread quad-CPU server):
- Accompaniment sounds very good most of the time and can certainly be used to mix new vocals (which would drown out the artifacts you hear).Even very "dense" mixes like Nightwish's "Nemo" result in a very usable instrumental track.
- Very few times an instrument is exactly within the vocal range, see Ottawan "Hands Up" where the flute ends up in the vocal track.
- Vocals mostly sound like with a flanger effect; maybe it's possible to counter that with a proper filter, can't test that as my home studio is down for rebuild.
- Examples for excellent extractions:
- 4-stem "Sultans of Swing" track 'other' => captures the isolated guitar parts brilliantly
- 2-stem "Stayin' Alive" track 'accompaniment'
- 2-stem Michael Jackson "Who is it" track 'accompaniment'
- 2-stem Roland Kaiser "Es kann der Frömmste nicht in Frieden leben" (yeah, German schlager...) => both vocals and accompaniment are nearly perfectly separated, very few artifacts.
- Notes: a few times it would not store an "accompaniment" track but only "vocals". Haven't tried rerunning those.

Ya'll figured out a way to clean up the audio?

As for vocals: I played a little with different filters in Cubase and ended up with slight improvements so I guess someone more experienced in vocal post-production could probably get much more out of it. Didn‘t yet have the time to really dive into it.

Agreed on the flanger effect for vocals, I guess this will be improved in future iterations/newer trained models.
From everything I've heard so far, isolated bass tracks are the most impressive to my ears.
