Any chance of you tracking down the official releases of this stuff? It seems like it was available on Spotify and Amazon at some point but has since been taken down. Or you could edit a rip from over on Zophar's Domain (or make your own). Good luck!
I noticed you did a great job with Duke Nukem 3D and while i managed to find the Redbook audio somewhere, no one has yet to do the standard audio. Maybe you could try your skills at that.
