Abstract
In this presentation, we will present a novel constrained adaptive beamformer algorithm that utilizes an inherent property of spherical harmonic eigenbeams which form the bases signals for spherical microphone array beamforming. Two simple constraints are placed on the weights to preclude the adaptive beamformer from nulling signals arriving from a desired “look” direction. The adaptive algorithm has been simulated for some simple acoustic fields as well as a diffuse field. We have implemented the algorithm in realtime on mh acoustics em32 Eigenmike¯ spherical microphone array and we will present some measurement results.
