摘要

A process assisted by computer means, for a spatialized sound reproduction from a network of loudspeakers (HP1, HPN) for the purpose of broadcasting a sound field chosen at a position of a listener comprises iteratively and continuously: - obtaining the current position of a listener, - determining the respective acoustic transfer functions of the loudspeakers in a virtual microphone whose position is defined dynamically as a function of the current position of the listener, - estimation d 'an acoustic pressure (P) in the virtual microphone (MIC), - calculation of an error between said estimated acoustic pressure (P) and a target acoustic pressure (Pt), - calculation and application of respective weights to the control signals ( S (HP1, HPN)) of the loudspeakers (HP1, ..., HPN), as a function of said error and of a weight forgetting factor, said forgetting factor being calculated as a function of a displacement of the listener, - calculation of the sound pressure in the current position of the auditor.
