A Ribbon microphone is a type of dynamic microphone that uses a thin metal ribbon placed between the poles of a magnet and generate voltages by electromagnetic induction. Ribbon microphones are generally the most delicate and expensive microphone. They are prized for their ability to capture high-frequency detail, comparing very favourably with condenser microphones, which can often sound subjectively "aggresive" or "brittle" in the high end of the frequency spectrum.
