Abstract
A sound image control apparatus and sound image control method capable of increasing the accuracy, in particular, in the distance direction while keeping fixed intervals of transmission characteristic filters, without increasing the number of the transmission characteristic filters. Sound image control apparatus 100 is provided with distance gain control section 101 that performs gain control of the sound pressure of an input monaural audio signal of one channel in the distance direction from a head to a sound image before input to virtual sound field 1 sound image localization section 120 and virtual sound field 2 sound image localization section 130 , and reflected sound gain control section 102 that performs gain control by distance of a reflected sound of the sound pressure of the input monaural audio signal of one channel before input to virtual reflected sound generating section 150 that controls the sound image to be localized outside the head when the sound is listened to with headphones.
