Which would be perfectly true if our ear functioned in the
same way as a PC sound card -- but (sorry to say) the human ear
is not a microphone and a sampler. The actual shape of the ear
does a transform on incomming sound so the first layer of processing
is done by acoustics. There is further processing done by feedback
around the sensing fibres. The short story is what gets to the actual
BRAIN (which is the area that was under discussion) is nothing
like the 44k stream of samples that goes through your CD player.
