Abstract: The invention relates to a method and the system for algorithmic processing of signals for sound spatialization making it possible to associate sound signals with information that has to be located by a listener, the spatialized sound signals being defined by a virtual position of origin corresponding to the position of the information wherein by algorithmic processing, a spatialized sound signal has an oscillatory movement applied to it describing a sequence of virtual positions of the said signal around the virtual position of origin. The invention applies to man-machine interface applications, notably in a cockpit avionics system. It makes it possible to better locate the information by associating with it a spatialized sound item of information.
