I've started to write a GUI for generating biquad coefficients

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.
Actually, why don't you push a [sig~ 1] through a [rifft~] and use
that as a probe with which you will connect to a spectrogram patch ?
(the probe's [rifft~] and the spectrogram's [fft~] have to use the
same block size.)
Because I'm doing this in Tcl... Its a GUI object.
