Each microphone type has a unique frequency response. It is important to remember that many manufacturers tailor a microphone's frequency response to accentuate particular parts of the spectrum to function optimally within a specific recording application. For the purposes of acoustic analysis, one should always choose microphones with a wide and flat frequency response curve.
