ABSTRACT

This paper proposes a novel approach of moving sound source localization using adaptive time delay estimation (TDE) algorithm and active-positioning of microphone arrays. Using the adaptive TDE that continuously estimates the time differences between the captured signals in the microphones sensors, the active-positioning controller keeps track of the source direction by rotating arrays mechanically. Theoretical analysis and computer simulations of the convergence characteristics of the proposed TDE algorithm are presented. The active-positioning array guarantees the highest delay-position sensitivity with smaller number of microphones than the fixed arrays. The overall performance is shown by using an experimental prototype system.
