Abstract
A method for spatialized sound reproduction using an array of loudspeakers, to generate a chosen sound field selectively audible in a first predetermined sub-area of an area covered by the loudspeakers, the area further including a second sub-area in which the chosen sound field is inaudible. The loudspeakers are supplied with respective control signals so that each one continuously emits an audio signal. The method includes, iteratively and continuously: estimating a sound pressure in the second sub-area as a function of the respective control signals of the loudspeakers, and of a respective initial weight of the control signals; calculating an error between the estimated sound pressure and a target sound pressure in the second sub-area; and, calculating and applying respective weights to the control signals, based on the error. The sound pressure in the second sub-area is calculated again based on the respective weighted control signals of the loudspeakers.
