Microphone directivity is a description of the microphone's sensitivity to sound from all directions in space, and it is an important indicator for purchasing a microphone. Generally speaking, there are omnidirectional, bidirectional, cardioid, super-cardioid, and gun-shaped microphones. The sensitivity to sound in different directions is very different.
Omnidirectional: This type of microphone picks up sounds in all directions when recording, and is equally sensitive to sounds from all directions. It is most suitable for picking up the environmental effects of the room, but it cannot effectively reduce or eliminate two noises. It is mostly used in meetings, speeches, etc. Multiplayer simple sound collection.
Bidirectional type: Mainly sensitive to sound from two directions, it picks up the sound of two measurements, rather than the sound of the front or the rear. The typical use is to place it between two musical instruments, or when two people stand face to face facing the microphone, so that the two sounds can be recorded together, while retaining the independence of the two.
Cardioid orientation: This microphone directly senses the sound in front, with a small extension range on both sides, and is sensitive to a wide range of sound in front of the microphone, but not sensitive to the sound from behind the microphone. It is mainly suitable for podcasting, personal singing, and instrument pickup Voice and other voice work.
Gun pointing: A type of microphone that pursues a single direction. The best radio angle is a small cone-shaped area directly in front, which can effectively reduce the collection of ambient noise. It is mainly used for outdoor radio, such as outdoor news interviews and film and television location shooting.
