FWIW was wondering how microphone manufacturers select 'matched pairs' when they have a big pile of mics.
They obviously won't take a mic and try to find the best next mic from
the population (say by summing their outputs and polarity-flipping one
in response to broadband noise) and then continue in this fashion for the next pair.
And then, do they match more on freq.response or on sensitivity ? Can become a compromise fairly soon, unless it's an A-brand manufacturer with tight fabrication tolerances.
Best way I could think of is that they make a freq-graph of each and
make pairs based on that...
but if they make these anyway, why don't you see them more often included ?
The matching for A-brands seems less fuzzy to me, but considering say a cheap matched pair of SDC-mics with actually not too bad matching I wonder how they do it.
Graphing each mic might be too expensive there I guess, so maybe they manage to maintain tight tolerances as well ? (be it at more crappy frequency-responses, hence indeed no plot supplied :wink: )
Bye,
