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 missing. 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. Cheers, Joachim.
