Pitch and TDOA-Based Localization of Acoustic Sources with Distributed Arrays

Research output: Contribution to journalConference article in Journal

Abstract

In this paper, a method for acoustic source localization using distributed microphone arrays based on time-differences of arrival (TDOAs) is presented. The TDOAs are used to estimate the location of an acoustic source using a recently proposed method, based on a 4D parameter space defined by the 3D location of the source, and the TDOAs. The performance of the proposed method for acoustic source localization is compared to the performance of a method based on generalized cross-correlation with phase transform (GCC-PHAT) using synthetic and speech signals with varying source position. Results show a decrease in the error of the estimated position when the proposed method is used.
