Vocal extraction software, what is everybody using these days

Hi,
I am looking to isolate vocals in A LOT of songs, and I'm looking for an accessible app to do this on an m1 mac mini. I know there used to be demix, which was run in the command line, but I can't seem to find any instructions on installing it on an m1 mac, as it's different than on standard silicon macs. It would be extremely nice to be able to isolate not only the vocals, but also separate lead vocals from background vocals, wow, would I love that! But I'm just looking for anything to separate vocals at this point. :) I know there are sites that do this, but they consume credits, which as fine, as long as I have enough of them, lol.
Thanks for any help anyone might be able to provide.
