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

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.)
