Yeah, the results are a lot better than filtering... deep learning has pushed the state of the art in source separation on quite a lot recently.
It isn’t magical and the results still have artefacts (mostly that kind of slightly underwater sound of a low bitrate MP3, I believe due to the way the audio is reconstructed from FFTs), and some songs trip it up entirely, but it’s definitely worth playing around with and I think it could potentially have applications for DJ/remix use if you added enough effects etc.
It’s fairly easy to install and runs quickly without GPU, or you can try their Collab notebook, or seems someone has hosted a version at https://ezstems.com/
