I agree with the general tone of your postings. I have expressed similar
sentiments in my original posting (analog delay line vs 'continuously
distributed memory'). However,  IMO, 'the signal is not simply
transformed at all' is not true. After all the cochlea does have
resonant structures and hence does some form of filtering  (which is
convolution with damped sinewaves, i.e. a  form of weighted Fourier
transform.)  I would like to fall into your third category.
