by generalized cross correlation( GCC) time delay estimation algorithm to estimate the relative delay between channels. Second
compensate delay time error generated by non-synchronous collection method by software. Third
the location of sound source is estimated by the two-step localization feature of time difference of arrival( TDOA) sound source location algorithm. Four element uniform linear array and planar four element cross array system are designed to verify the above methods
the results prove the method can more accurately realize the estimation of the sound source orientation.
