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 activepositioning 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 activepositioning 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.
