Array Microphones

Multiple microphones (from two to hundreds) arranged to obtain directionality, either by direct summing of all microphone's signals or by adding signal processing to the summation process. Examples of arrays: Endfire microphone: Microphone elements arranged in a straight line, all units time-aligned to the element furthest away from the sound source. Sphere microphone: Microphone elements distributed on the surface of a rigid sphere. (Typical sizes: 10-25 cm diameter). The use of signal processing then obtains beamforming. The signal can be extracted into several audio channels providing multichannel options.
