..if you want to do a ton of concurrent analysis, and have openGL acceleration working, Tapestrea might be cool (ATI hates me too much for using linux to let me try it)

if you dont mind the analysis being offline, check out sonic visualiser:

CLAM might have one. see a full-color spectrogram in one of the screenshots, but not in the patcher view:

in PD, just make a FFT transform of a signal block. this can be found in a number of help patches..

you'll also want lots of controls to adjust the amplification, logarithmic scaling, color palette, etc..

http://whats-your.name/i/licker.png is what i use , sure it uses more CPU than a C implementation, but its more flexible, and you can plug it in anywhere in your patch..
