Microphone arrangement
In the simplest case for stereo recording, a microphone arrangement or a microphone system consists of two microphones which form a system and the level differences Δ L and transit time differences Δ t generated by them ensure the required imaging width on the stereo loudspeaker base .
The coincidence microphone arrangements XY stereo system and MS stereo system , the AB stereo system and equivalent stereo systems such as ORTF stereo system and NOS stereo system are known . These microphone arrangements are mostly used as the main microphone , with an idea of the pick-up area of the respective microphone system.
More than two microphones can also form a microphone system, as shown, for example, by the Decca Tree , which is used for stereo recording and surround sound recording.
Special 5.1 surround sound microphone systems are also used in the cinema .
In acoustic measurement technology, microphone arrays are used .
