There is a nasty peak in my speakers' response curves, so I aim to get a
equalizer (maybe a parametric one) to pull that out. First I need to know
where (in Hz) and how wide the peak is.
I suppose I could find relevant tones on the piano, but it'd be more
accurate (I think) to do it computationally. So, I'm looking for two
things: a pitch generator and an app to make a frequency vs amplitude graph.
(There's a name for that kind of graph, maybe "Fourier Transform". Snd can
do it but I don't see how to get a number out of it.)
I realize the microphone and sound hardware can themselves introduce
nonlinearities, but there's not much I can do about that. What do you
suggest?
