I have a couple DSP-for-dummies questions.
I'm still intrigued by the idea of getting a proper Auto Wah-Wah sound going.
I like the approach of building one out of LADSPA plugins.
My question is this: what tools would I use on Linux to analyze the frequency response and
characteristics of the many, many LADSPA filter plugins, so as to decide which has the
response closest to a real wah circuit (i.e. a lowpass with a resonant peak just above the
rolloff point)?
What I'm going for is this:

I don't know squat about DSP, otherwise I might just try coding something up; the
LADSPA spec looks pretty straightforward.
