Abstract
A microphone assembly includes at least three microphones to capture an input audio signal; an audio signal processing unit for processing the input audio signals to generate an output audio signal with a directivity; an audio source direction estimation unit; and a control unit. The audio source direction estimation unit includes first and second direction of arrival estimation modules for estimating first and second angles of incidence between an audio source and first and second axes defined by first and second pairs of the microphones, respectively; and an elevation estimation module for estimating an angle of elevation of the audio source with regard to a microphone plane based on the estimated first angle of incidence and the estimated second angle of incidence. The control unit uses the estimated angle of elevation to control a directivity parameter of the audio signal processing unit.
