[0003] Microphones are classified according to their directivity, and there are three main types: supercardioid, cardioid, and omnidirectional. Among them, the supercardioid is used in scenes with a relatively long pickup distance and can shield more surrounding environmental noise; the cardioid is used in scenes with a short pickup distance and can shield some of the surrounding environmental noise; the omnidirectional will pick up all the surrounding sounds. At the same time, microphones are classified according to the channel, and there are two main categories: mono and stereo.
