https://github.com/Ardour/ardour/blob/master/gtk2_ardour/fft.cc Is what generates the effect analysis (frequency and phase response) in Ardour. The code is quite easy to [re]use. Just feed a delta impulse into your filter, call FFT::analyze() with the result and you get two arrays: power_at_bin[], phase_at_bin[] YMMV.
