A sound image localization processing apparatus is provided, in which a surround system is realized by a front speaker with a simple signal process, and the same side localization effect can be given to a plurality of listeners. A sound image localization processing apparatus 100 causes two speakers FR, FL disposed at the right and the left in front of a listener to output sound in accordance with a plurality of supplied sound signals, and gives a sound space with a sense of realism to the listeners. The apparatus 100 comprises: signal processing means 200 for controlling a phase of a right signal indicative of sound signal which should be heard from the right side, and a left signal indicative of sound signal which should be heard from the left side, relative to a listening position of one of the listeners, and localizing a sound image at a side of one of the listeners frequency-band division means 200 for dividing the processed sound signal by a predetermined frequency band, and signal correction means 200 for assigning each listener to the divided frequency band, controlling a phase of the right signal or the left signal which has been signal-processed for a listening position of the other listener, and localizing a sound image at a side of the other listener.
