A Novel Method of Acoustic Source Localization Using Microphone Array
The acoustic source localization is widely used in tele-conference system. This article proposed a novel acoustic source localization algorithm for microphone array which is based on delay-and-sum beamforming and GCC-PHAT. The algorithm shows that time delay between microphones on a basis of GCC-PHAT can be estimated and localize the acoustic source in search space by using improved delay-and-sum beamforming algorithm. Experimental results demonstrate that the proposed algorithm is much more robust than TDOA alone as well as SRP-PHTA algorithm when in noise and reverberation environment.
