Abstract
Herein provided is a method and system for directional enhancement of a microphone array comprising at least two microphones by analysis of the phase angle of the coherence between at least two microphones. The method can further include communicating directional data with the microphone signal to a secondary device, and adjusting at least one parameter of the device in view of the directional data. Other embodiments are disclosed.
