Abstract
An adaptive differential microphone array method comprises receiving a signal, estimating a measured signal spectral covariance matrix of the signal, and estimating a direction of arrival of the signal based on the measured signal spectral covariance matrix of the signal. The method further comprises determining a fractional delay, and applying a differential microphone array filter to the signal based on the direction of arrival and the fractional delay.
