Thanks for the PC tracks, but it seems that cut off is at 16khz meaning that the output was at 32khz. I'm unsure why the flacs are at 44khz. Just a heads up to anyone that might want to download.
The Turoks on PC use red book audio so they're stored as 44KHZ. For completeness here's the first one though IMO the N64 sounds better. Turok No water music here either.
I have no idea what bucky's talking about (or the person who posted the comment in one of his videos).
The first stage is "Port of Adia", which has a length of about 5:18 before looping from about 0:32, i.e. with a loop length of 4:46
Other lengths I can confirm are River of Souls (5:05 total, 4:20 loop), Death Marshes (10:33 total, 8:13 loop), and Primagen's Lightship (5:56 total, 4:52 loop)
