At the risk of slightly derailing the topic, but it kinda being related because FFT and resolution...For what it's worth, my general purposes analyzer does a combination of 3rd octave (with order 6 or 8 filters per band, forgot what it was exactly) and then it has FFT mode (with zoom and spectral slope-weighting and what not) separately. The 3rd octave is better for getting an idea of the spectral balance while the FFT is a king for surgical analysis.
I'm using an FFT with an impulse to render filter responses. The sort of thing that Serum does for its filter display. It's useful for a large number of different filter types where computing some kind of Z transform would be a royal PITA.
As you might expect though, it loses resolution in the lower bins and can look a bit lumpy. Is there a way of getting a smoother more even visual with this technique? I'm figuring you'd be the one to know
