Abstract
Accurate and computationally efficient estimation of time delay of arrival data for localization of a sound source is described herein. A number of independent time delays are retained and validated through comparison with a set of dependent time delays. The method is robust against detrimental effects in the environment such as noise and reverberation. The resulting delays may then be used in sound source localization or other signal processing applications.
