Perhaps I wasn't clear enough.  My example was illustrative and by no
means was I implying that decorrelation alone is a model of auditory
development, neither that deriving a new transform is perceptually
relevant.  I was merely advocating a more mature and creative use of
what people perceive as ugly and stagnant math.  After all math, like
english, is only a language to express ideas with, its expressiveness
lies within its use.

The function of audition is not the only holy grail here.  One can only
do so many interesting studies on modeling the cochlea, looking at
neural spikes, or grouping tones.  I hope everyone in the list accepts
the fact that there are also interesting questions involving the
development of audition, its driving principles, and its integration in
the perceptual system, regardless of precise modeling.
