This example illustrates using beamscan, mvdr, and music for direction of arrival (doa) estimation beamscan is a technique that forms a conventional beam and scans it over directions of interest to obtain a spatial spectrum. The direction of a sound source is estimated in real time and indicated to the user via four light-emitting diodes designating the front, back, left, and right directions two methods for estimating the sound direction were compared: delay-and-sum beamformer and sound pressure level (spl) comparison. The estimation of the direction of the source can then be obtained through the use of the far-field model  the far-field model assumes that the receivers are far.
