I've started to write a GUI for generating biquad coefficients
(something like Max/MSP's [filtergraph~]). I've gotten the GUI
interaction working well, now I'm looking for the algorithms for
generating a plot of the frequency response of a given set of biquad
coefficents? It'll end up being Tcl, but I can easily read C, Csound,
Java, Perl, Python, etc.
