Microphone base

The microphone base is the distance between two microphones in a stereo microphone system. This means that the distance between the microphone capsules is to be understood precisely. This distance is decisive for signal transit time differences in stereo recordings according to transit time stereophony and equivalence stereophony .

The microphone base must not be confused with the distance of the microphone or the microphones as the " microphone distance " to the sound source or the sound body.

Furthermore, the microphone base is decisive for the recording area , which is usually specified as the total angle . The following applies: the larger the microphone base, the smaller the angle of the recording area.
