Comb Filter and Pitch shift

I’ve noticed that using DaisySP/comb.h at master · electro-smith/DaisySP · GitHub results in a pitch shift. i.e. the lower the SetFreq value the lower the apparent pitch. Is this expected? I’m a filter newb so probably missing something in terms of expected post processing?

a friend made a comment that a comb filter can be thought of a delay, which is true. so i guess my question could also be phrased as “what’s a good way to compensate for a pitch shift when running a delay”. this is all new to me sorry :confused:

Yes a comb filter has a “pitch”, it resonates at its fundamental frequency (given here with SetFreq()) and their harmonics, producing a distinct tone.
