Abstract
A sound image localization control apparatus provided with a pair of convolvers for performing a convolution operation on signals sent from a common sound source, a storage unit for storing groups of coefficients of localization filters (namely, impulse responses) corresponding to each of locations of sound images and a coefficient supply unit for supplying the coefficients corresponding to a designated location of a sound image to the convolvers. The sound image localization control apparatus can make a listener feel as if sound images are localized in a large space as subtending a visual angle of more than 180 degrees at his eye. The sound image localization control apparatus is further provided with a synchronization unit for localizing a sound image in synchronization with an image reproduced on the screen of a monitor. The sound image localization control apparatus can provide virtual reality with more realistic presence.
