I'm against the useless physical units and denominator. Just the ratios of the positions to one another matter; the whole thing is scale-invariant for all practical purposes.
Well, it is not scale-invariant, yeah the world sucks ... The speed of sound is not infinite and more distant speakers will have their signal hit the listener later. That causes a phase shift and could change a 2*sin() to 0*sin().
In the range of sane distances, is this really an issue? I'm thinking anywhere from headphones to theaters. Somehow I suspect the speed of sound and the frequencies involved make it irrelevant but I didn't work out the math.
So a system of a speaker at 1m and one at 2m will would sound different from one with a speaker at 1km and 2km (with the volume turned up sufficiently)
WOW I want those speakers! :)
Iam not saying that there is any need or sense to store this nor that i would know what a decoder would do with that information, but i do know copper purity counters will prefer NUT over other formats if the distance is stored.
Well I would like to see some mathematical/physical reason that it's potentially useful rather than the opinions of people who pay for solid-gold *digital* audio cables to give their sound "more body"...
Otherwise I don't see anything wrong.
good, what about the flag to skip the stuff = unknown pos? Do we want one if not what should be muxer store if it doesnt know the pos?
I suspect skipping pos should not be legal for >2 channels.. For 2 channels or fewer, making it optional would be nice. Rich
