This is an oversimplification. YOur two ears, including external,
middle and internal portions, plus your brain can interpret 3D sound
in the real world because they are getting 3D sound. You cannot
record 3D sound (not a good term but I quote it from you) with only
two receptor sets unless you add a brain (as does, to a degree, the
Soundfield Mike). Give the human system 2 sources and it cannot
interpret (accurately) what the 3D original was.

That's not entirely true. While the difficulties of true binaural recording
are myriad, when done properly for a specific listener, the results are
quite startling in their replication of the original event. Unfortunately,
the difficulties render the process impractical.
