==Original Abstract Submitted==

a method for determining a direction of at least one sound source using an audio system capturing by an array of microphones sound emitted by the at least one sound source. the method includes: emitting a sound by way of the at least one sound source; recording sound signals received by the array of microphones; executing cross-correlations between the received signals in order to deduce relative times of arrival therefrom; creating a sinusoidal function of time having a determined frequency and a phase offset dependent on the relative times of arrival; and computing to determine a direction value of the sound source in a spatial reference frame defined by the array of microphones, using the values computed from the sinusoidal function of time at input, presenting the direction value.
