Abstract
Several source localization algorithms have been proposed in the literature for acoustical source localization. Many of these algorithms make use of the generalized cross correlation (GCC). In order to facilitate the comparison between algorithms, the properties of the GCC should be as well understood as possible. In this work, it will be shown that by changing the assumptions on the signal, a more accurate model of the GCC can be obtained. This model will be used in several scenarios to compare localization algorithms
