摘要： An acoustic image localization apparatus according to the present invention that outputs sound from a plurality of speakers so as to localize an acoustic image at a predetermined position on a space as viewed from a listener, the acoustic image localization apparatus comprising: amplitude characteristic adjusting means for adjusting an amplitude frequency characteristic of an inputted acoustic signal such that the acoustic image is localized at a position rotated by a first angle about a position of a listener toward an upper direction from a facing position of the listener; and a plurality of level adjusting means, provided so as to respectively correspond to the plurality of speakers, for adjusting a level of the acoustic signal outputted from the amplitude characteristic adjusting means and for outputting, to a corresponding speaker, the acoustic signal whose level has been adjusted, wherein each of the level adjusting means adjusts the level of the acoustic signal, which is outputted from the amplitude characteristic adjusting means, to a level of the corresponding speaker such that the acoustic image is localized at the predetermined position rotated by a second angle about the position of the listener toward one of directions orthogonal to the rotated directions from the position rotated by the first angle.
