Illusonic

Illusonic's patent pending surround microphone technologies, based on coincident microphone arrays, simulate highly directive microphones for each of the multi-channel surround channels to be recorded. The result is high channel separation, while maintaining high signal fidelity.

Two Channel 5.1 Surround Microphone
Signals of conventional stereo microphones are processed to simulate five virtual microphones to generate 5.1 surround audio.
