PURPOSE: To provide a sound image localization controller in which a listener M (operator) senses as if a sound image localized at an optional desired position in the sound field reproduction of a game machine or the like.
CONSTITUTION: The sound image controller is formed by a couple of convolvers 1, 2 applying convolution arithmetic operation processing to a signal from a same sound source (X), a storage means 3 retaining a coefficient group (impulse response) for cancel filtering use at each sound image localized position, and a coefficient supply means 4 supplying a coefficient corresponding to the designated sound image localized position to the convolvers. Then a signal subjected to convolution arithmetic operation processing by the convolvers 1, 2 is reproduced by a couple of speakers sp1, sp2. Thus, a listener (M) senses as if the sound image were localized at an optional position (x) by varying the coefficient set to the convolvers 1, 2.
