Alas, whle baudline is indeed a wonderful application it doesn't do a 
true waterfall display. Please see the results on Google for 'alan 
peevers spectrogram' for more info regarding what I'm looking for.

Btw, there's a way to set Cthugha to do this, and I believe it might be 
possible with Pd. Snd creates a nice OpenGL FFT display but it's not 
realtime.

Best,
