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, 'A real-time srp-phat source location implementation using stochastic region contraction(src) on a large-aperture microphone array,' in Proc. IEEE Int. Conf. Acoust. Speech, Signal Process., Honolulu, HI, April 2007, vol. 1, pp. 121 124.

Audio Noise Gate for Texas Instruments C5510 / C6713 - Used on cellular phones to filter out background noise. Measure the signal to noise ratio of an audio input in realtime. Pass speech but give silence where the input is noise (hiss, snap crackle and pop).
Shareware Connection periodically updates pricing and software information of 'Acoustic source localization using SRP-PHAT' from company source 'Hoang Do' , so some information may be slightly out-of-date. You should confirm all information before relying on it. Software piracy is theft, Using 'Acoustic source localization using SRP-PHAT' crack, password, serial numbers, registration codes, key generators is illegal and prevent future development of Acoustic source localization using SRP-PHAT.
