My partner plays violin and was looking for a version of Lindsey Stirling's Crystallize without the violin part (or rather, with it turned down.)
I found plenty of tools online to do this, but they were all credit-based and a bit annoying to use. I eventually found they were mostly using Demucs from Facebook: https://github.com/facebookresearch/demucs
Really nice tool if you need simple splitting of things like drums, vocals, etc. It's not perfect, but it's a great start.
Yes, the Demucs mixing model has excellent SNR performance, but it is computationally intensive. It also incorporates a random mechanism, so each time it produces different spectrograms.
