Abstract
A direction of at least one sound source from an array of microphones is determined by obtaining a plurality of solutions sets from audio signals acquired from the microphones array, each solutions set being obtained by applying a sound source localization method to the audio signals, each solution defining a sound direction candidate. Then, solutions are grouped into groups of solutions and at least one of the groups is removed, based on a criterion of disparity between the solutions sets. The direction of the at least one sound source from directions associated with the remaining groups is obtained.
