I'm running BIAB 2021 (latest version) on a cheapo HP Pavilion Slimline 400 PC desktop and it works fine (also on low end HP laptop) - I really have no complaints. I mostly use it for making Mp3 backing tracks for solo gutar (country and jazz standards). I sometimes, but rarely output to Reaper - mostly just output as an Mp3 from BIAB and play them off my tablet or phone. While I have no complaints about the sound quality of the files I'm getting, I'm curious if there's a way to improve it via some sort of external sound card or module. I mostly use Real Tracks so a midi module doesn't really enter the picture (used to use one years ago). I assume the sound card on my PC is integrated into the motherboard and doubt there's even a slot for a better one. Not sure if there's any room for improvement - just thinking out loud. Any thoughts?
