A digital parametric equalizer is too pretty for me. I wanted something that would show all the phase anomalies created. -- currently under development.
Mostly just here so I can remember what the hell everything is.
Response to a short duration time signal
Transforms functions to be characterized by sines and cosines. Transforms from time domain to the frequency domain. i.e. f(time) to F(freq)
Just the opposite of the Fourier transform. i.e. F(freq) to f(time)
