Subject: Re: perceptual evaluation of cochlear models From: Joachim Thiemann <joachim.thiemann@xxxxxxxx> Date: Wed, 3 Sep 2014 08:12:08 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hello Francesco, McGill alumni here - I did a bit of study in this direction, you can read about it in my thesis: http://www-mmsp.ece.mcgill.ca/MMSP/Theses/T2011-2013.html#Thiemann 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.
