Sorry, still continuing the off-topic with this subject.

Hehe. A propos Blumlein:
Reminds me of the story told in the Blumlein biography, which explains how
Blumlein became interested about "binaural" (as he called it) audio in
cinema
in the first place.
Alan Blumlein had been watching a film with his wife. He asked her after the
performance: "Can you hear that the voice is not coming from where the
actor is?"
His wife hadn't noticed that. Blumlein said that "I know how to fix that".
That's when he started to develop spatial sound for the film. His
original idea
wasn't to create auditory space for the film sound, but to make the
audio image
follow the actors moving in the picture. He did this. See "Walking and
talking":

Blumlein's original idea wasn't used for a very long time. The voices
following the
image was used only during a relatively short period in widescreen
movies (many
of them Cinerama and similar formats) in the USA in the 50's. Just watch
Oklahoma in stereo and enjoy. :-)
Ever since, 99% of all dialogue has been placed in the center channel
for the
reasons Dave is describing.
There are even more reasons. The timbre of the voice is different, if it
moves away
from the center channel.
