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.
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.)
