the cookbook
is a bitch to read without the background. i guess it's
meant to serve as a quick lookup sheet for people who know the stuff
but can't remember the exact numbers. if you're looking for bi-quads,
those in ecasound seem to follow the cookbook iirc.
So do some of the ones in my plugins (utils/biquad.h has a complete
implementation)
yes, i forgot to mention. too obvious a place to look in. :)
