Re: [AUDITORY] PESQ
Can you point us to the document that has this information? I highly doubt this.
The paper describing PESQ is publicly available (to IEEE members), which means everyone can implement and use this metric:
A.W. Rix, J.G., Beerends, M.P. Hollier and A.P. Hekstra, "Perceptual evaluation of speech quality (PESQ)-a new method for speech quality assessment of telephone networks and codecs," in Proc. IEEE ICASSP, Salt Lake City, UT, May 2001, pp.749-752.

I just found out that the _academic_ use of PESQ (perceptual
evaluation of speech quality, ITU recommendation P.862), that is
described with MATLAB source code in Loizou's Speech Enhancement
book, requires a license that costs around $7000 per year. I write
this as a warning for others against using it (unless you happen to
have the spare cash), because we didn't know this and did a lot of
work with it that we now can't publish.
