DIN Stereo Microphone array

An acronym for a German standards organisation founded in 1917: Deutsches Institut für Normung. Amongst many audio standards created by this organisation, the DIN stereo microphone array comprises a pair of near-spaced cardioid microphones with capsules spaced 20cm apart at a mutual angle of 90°. The resulting SRA is 101 degrees. This technique captures both time and level differences between channels, and is comparable to similar techniques such as ORTF, RAI, EBS, NOS, and others.
