Hi, I am conducting a little study on filters and currently finding a way to obtain their frequency response by feeding them a wideband signal and plotting their FFT.
I am new to the PD environment and currently the best I could do is generate N/2 oscillators with different frequencies (N being the sample size of the audio buffer). I am sure there is a smarter way of doing this (generating lists for the oscillator frequencies and/or sequencing them). Any suggestions?
I could write an external but a relatively simple subpatch or expression is better.
As an alternative I could feed white noise and average the FFT curves over time, but the result would not be as smooth.
