Re: perceptual evaluation of cochlear models

Hello Francesco,

McGill alumni here - I did a bit of study in this direction, you can
read about it in my thesis:

My argument was that if you have a good auditory model, you should be
able to start from only the model parameters and be able to
reconstruct the original signal with perceptual transparency.  I was
looking at this in the context of perceptual coding - a perceptual
coder minus the entropy stage effectively verifies the model.  If
artefacts do appear, they can (indirectly) tell you what you are

I was specifically looking at gammatone filterbank methods, so there
is no comparison to other schemas - but I hope it is a bit in the
direction you're looking at.
