Recently, new approaches for sound-image localiza-tion1,2) have been developed based on a model of hearing.However, they are applicable only to twoloudspeaker one-listener case.The method proposed here is their extension to multi-loudspeaker multilistener case.Although our method cannot offer the optimal configuration of loudspeakers and listeners, it provides the least-squares solution for the transfer characteristics of the channels to the loudspeakers for given configuration of loudspeakers and listeners.This method is one of the applications of the generalized inverse of matrices to acoustic signal processing.3)
