Abstract
A sound reproducing system in which virtual image orientation processing of audio signals for at least two rear speakers disposed in directions from a listener close to the right-back direction from the listener is performed by a virtual sound orientation processor so that the listener can have a sound image at a position different from each of real speaker positions at which the rear speakers are placed, and/or so that the listener is unconscious that sounds are radiated from the rear speakers placed at real speaker positions. This virtual image orientation processing is performed according to acoustic transfer coefficients of transfer of sounds from the rear speakers to the listener's ears when the rear speakers are placed at virtual speaker positions different from the real speaker positions.
