Hi, I am created a pitch detector and I have noticed that I get shifted results depending on which microphone I use. Has anyone else noticed this type of behavior? I've created a calibration curve to compensate but the shift did surprise me a bit.
Should there be a frequency shift dependent on microphone?

That doesn't apply to amplitudes. Probably, your microphones emphasize different harmonics, affecting the software you use.
