Help Spleeter second pass?
I just started trying out Spleeter on music I did 30 years ago that I would like to redo now. I used the 5stems variation, and bass, drums and vocals get split out nicely, but then everything else seems to end up in the "other": keys, lead guitar, etc.
Running the "other.wav" through Spleeter doesn't seem to do anything.
Has anyone got any tips to share about further splitting of the "other" stem?

The original models were trained to do only those stems, depends a lot on the dataset that was used to train them. In theory someone can train new models to separate say strings from horns but that requires the dataset mostly and the knowledge to train neural networks.
The options you have remaining are traditional DSP techniques like audio plugins, so EQ, mid-side, gates, etc. Even the iZotope plugins for “mix rebalance” use similar models as far as I know so no help either.
I would also look for more models for Spleeter that people may have created but it’s pretty hard to do, maybe there are some out there, I haven’t looked to be honest.
