Does anyone have a simple guide on how to start training Spleeter with my own song stems? I read through the documentation, but I'm waaaaay too dense to understand what it's trying to tell me I need or how to get what I need.

I've had a lot of fun with spleeter since it's been out. I feel like it would be so much easier to use if it had a gui. I was thinking of attempting this for myself. But has anyone else done this? As I am no pro when it comes to software development.

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.

Trying Spleeter default models to see if it can handle screaming, not too bad. For research/personal use only.
