I was indeed talking about digital filtering in the post processing part (after capturing the signal and hardware anti-alias filter, but before doing beamforming by software). I knew I was forgetting something. Like the filters have to be matched closely between microphones (which is the case when filtering using software). Then the possible phase change introduced doesnt matter as the relative phases between microphones stays the same. So in short, I was forgetting the filters have identical characteristics. | |
