That, and how would csound report in real-time? I know it has some fltk
extensions to do something like that graphically, but I'm not sure
whether it offers anything beyond a simple print-like function for the
console.

I thought of that: one could split up the frequency range using a bunch
of chains with bandpass filters, but here again, how to measure and
report in a timely, readable matter?

I'd rather go the simplest route possible, since I don't need anything
too fine-grained.
