No, I was talking about spectral artefacts - and not localization.
To apply Heisenberg’s Unschärferelation to acoustics might be a bit
audacious, because the size and energy orders are just too big for. 😉

But you can't have it both ways:
Either these small changes are noticeable, but then you also will
get some spectral = tonal errors. (You don't get tonal errors in
the case of normal head movements, according to Dr. Theile and
others. Even if the spectral perception changes because of head
movement...)
OR the changes are too small to get noticed, or tp do anything
meaningful in the first place...
You might be dealing with the uncertainty principle, here. Not sure,
but it sounds like you might.
It is impossible to localize in time and frequency at the same
time. That's just basic math. If you do a Fourier analysis of
things, the two sides of the tranform obey the Heisenberg principle.
If you want to go into a more Surround Sound or DSP minded
discussion, I'm more than willing and here. :)
