From what source? To be a remaster you'd need access to the original tracks or even higher quality ones. If you used the in-game music it's not a remaster, at best it's a remix.
Good job! I han hear some artifacts here and there (those fast guitar and bass parts especially) but it’s not distracting and compared to the originals side-by-side much more enjoyable.
I‘d love it if you could take a swing at the Zerg. Which AI did you use and for what, if you don’t mind me asking.
For the instruments I have a private plugin originally based on spleeter and I have LALAL.ai. Some tracks (like the drums) which it's not as good for, I get my buddy to extract in FL studio (its implementation is surprisingly not terrible) since I use ableton. Sometimes the result is good, sometimes it's not. There's only so much you can pull out of these old tracks but the fact we can do it at all is pretty mind-blowing.
I on the regular like to go back and listen to stsrcraft's soundtrack. So many hours spent in that game, oh the memories. I'm definitely going to listen to this!
