Acoustic source localization using SRP-PHAT 1.0

This function localizes a single source from a frame of data received at the microphones. It uses the Steered Response Power with the PHAse Transform (SRP-PHAT) as the functional. The true source location will have the maximum SRP-PHAT value. Stochastic Region Contraction (SRC) is used as the global maximum search algorithm in the function. Using SRC cuts down the computational cost of SRP-PHAT based algorithm by more than 3 orders of magnitude compared to that of a full grid-search.This work is based on the algorithm presented in:H. Do, H. F. Silverman, and Y. Yu, d-deDUA real-time srp-phat source location implementation using stochastic region contraction(src) on a large-aperture microphone array,d-deDt in Proc. IEEE Int. Conf. Acoust. Speech, Signal Process., Honolulu, HI, April 2007, vol. 1, pp. 121d-deOCt124.
