A method for localizing a sound source including the following steps: a) capturing sound signals issued from a sound source to be localized by means of a set of at least three microphones (M1, M2, M3, M4); b) selecting at least three pairs of microphones from said set and, for each said pair, calculating a generalized intercorrelation of the captured sound signals, said calculation being carried out for a plurality of values of a delay - called the interaural time difference - between said sound signals; c) from said generalized intercorrelations, calculating a steered response power expressed as a function of a vector of the interaural time differences for each said pair of microphones; d) determining the interaural time difference vector that maximizes said steered response power; and e) estimating a localization direction of said sound source as a function of the interaural time difference vector determined in step d), characterized in that : - said steps c) and d) are implemented by considering a plurality of interaural time difference vectors forming a set (E) that comprises: a first subset (E1) of vectors compatible with sound signals originating from a single sound source at infinite distance from said microphones; and a second subset (E2) of vectors that are not compatible with sound signals originating from a single source at infinite distance from said microphones; in that : - each vector of said first subset is associated with a localization direction of the corresponding single sound source, and each vector of said second subset is associated with the localization direction associated with a vector of said first subset that is closer thereto according to a predefined metric; and in that : - the direction estimated in said step e) is that associated with the interaural time difference vector determined in said step d). a) capturing sound signals issued from a sound source to be localized by means of a set of at least three microphones (M1, M2, M3, M4); b) selecting at least three pairs of microphones from said set and, for each said pair, calculating a generalized intercorrelation of the captured sound signals, said calculation being carried out for a plurality of values of a delay - called the interaural time difference - between said sound signals; c) from said generalized intercorrelations, calculating a steered response power expressed as a function of a vector of the interaural time differences for each said pair of microphones; d) determining the interaural time difference vector that maximizes said steered response power; and e) estimating a localization direction of said sound source as a function of the interaural time difference vector determined in step d), - said steps c) and d) are implemented by considering a plurality of interaural time difference vectors forming a set (E) that comprises: a first subset (E1) of vectors compatible with sound signals originating from a single sound source at infinite distance from said microphones; and a second subset (E2) of vectors that are not compatible with sound signals originating from a single source at infinite distance from said microphones; in that : - each vector of said first subset is associated with a localization direction of the corresponding single sound source, and each vector of said second subset is associated with the localization direction associated with a vector of said first subset that is closer thereto according to a predefined metric; and in that : - the direction estimated in said step e) is that associated with the interaural time difference vector determined in said step d). <EOS>
