Abstract
It is an object of the present invention to provide a sound image localization apparatus which can localize a sound image with ease correctly for many listeners. Herein disclosed is a sound image localization apparatus, in which a directional band information storage unitis adapted to store therein directional bands in advance calculated for respective directions, a control filter computing unitis adapted to read a directional band corresponding to a target position information from a directional band information storage unitupon receiving target position information, calculate a control filter coefficient in such a manner that the maximum value of a sensation level for which masking is taken into consideration is matched with the directional band thus read, output the control filter coefficient to a sound image localization processing unit. Upon receiving the control filter coefficient from the control filter computing unit, the sound image localization processing unitis adapted to convolve the control filter coefficient thus received to an inputted sound source signal, carry out sound image localization processing on the sound source signal, and output a sound signal whose sound image has been localized as a sound image localization signal to a sound reproducing device, not shown, such as, for example, headphones, a speaker, and/or the like.
