what it does is inverse-map the 5 coefficients of the biquad filter to 5
parameters that users might find useful. there *are* only 5 degrees of
freedom, so it really is only an issue for how you want those 5 control
why not put out a request for anyone here at music-dsp who has free
access to the full AES archives (i don't, sorry) to send you the pdf?
maybe there is a similar paper by the author living out there in the
internet. maybe you can find and contact the author. i have a paper
copy of the preprint *somewhere*, but i am not sure where.
