The human ear basically "just" constructs a spectrogram, as far as I now.
The other feature detectors that act on this spectrogram reside in the
brain, not the ear. (You even said so yourself.) So how can you say that
it is the _ear_ that makes such a difference? Your examples do not support
your conclusion.

All those things that the brain do with the signals from the ear, can
also be done by a computer working on the digital signals directly from
the CD. Are you arguing that it makes a difference whether the further
processing (feature detection) is done in the "brain" or in the
"transduction unit"??
