In a microphone, the diaphragm excursion is so small that any possible
Doppler shift would be negligable, even assuming that there is Doppler
shift
in a mic. BTW, if there is Doppler shift in a microphone because of
diaphragm excursion, then there must also be Doppler shift in the human
ear
because of the excursion of the eardrum, and if that is true, our
hearing
mechanism must have compensation built in, so, since the amount of
excursion
in the mic and the eardrum are similar, if there is any Doppler shift in
a
mic, it can be disregarded.

What a load of crap. Whilst I agree that any doppler in a microphone would
be minute, it would not be compensated for by the ear/brain just because
it
may be similar magnitude to the eardrum.

It seems that you missed the point, which was that if there is Doppler
shift in a mic because of diaphragm motion, then there must also be Doppler
shift in the human ear
because of eardrum motion. If that is true then the hearing mechanism must
have a method of compensation for it.
