[ProAudio] 4-channel program distribution format(s)

Hi, All,

I was asked to digitize a small collection of the early work of of an 
electronic music composer from the 1960s and 1970s. The person 
sponsoring the work would like to know how to possibly distribute these 
recordings, perhaps for sale, but is interested in preserving them for 
as long as possible.

The obvious suggestion is WAV files in a trusted digital repository. I 
already have the sets of 4 mono WAV files at 192/24 that I made. The 
question is "now what?"

One friend says he doesn't know much about the mechanics, but his Oppo 
player will handle just about any released quad he's found either on an 
optical disc or on a thumb drive downloaded.

Are there any standards for formatting multichannel WAV or FLAC files 
(both are capable of this). The composer's standard was starting at rear 
right (1) going clockwise to front right (4). My few 1970s recordings in 
quad were 1,2 and 3,4 for front/rear--I think--though the one quarter 
track one I did was perhaps LR LF RF RR to keep the front channels away 
from the edges--I haven't seen that tape for years, but I may still have 
it. I was fairly good with metadata from the start.

Is there any ISO standard for 4.0 distribution?

Any help/suggestions on how to do the "right" thing would be 
appreciated! I have spent time searching, but I'm not finding the right 
keywords, I guess.

Quality tape transfers -- even from hard-to-play tapes.
