The audio options include all three 1977 mixes in DTS-HD-MA format; the original 70mm six-track was recreated by hairy_hen,
the original stereo mix was captured from LaserDisc PCM and fixed up by hairy_hen and the original mono mix was restored
by Belbucus. Also included is an isolated score track, four different commentary tracks and a British commentary
for visually impaired.
This is very minor, and maybe intentional on your part, but in this paragraph you do not mention the 1985 and 1993 mixes. They don't necessarily need to be mentioned here since they are part of the overall list, but I figured I'd point it out just in case.
