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().

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)

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.

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?
