Abstract
With stereophonic sound images of multi-channel audio signals well maintained, 2-channel system audio signals are created. An acoustic image creation system includes: a left-rear localization processing meansfor outputting a left-rear localization signal by summing together a left signaland a left-rear signal, among audio input signals including the left signal, a right signal, the left-rear signal, and a right-rear signal, and processing the summation result with a rear localization processing filter; a right-rear localization processing meansfor outputting a right-rear localization signal by summing together the right signaland the right-rear signal, and processing the summation result with a rear localization processing filter; and an acoustic image creation meansfor creating the surround sound image signals from the left signal, the right signal, the left-rear localization signal, and the right-rear localization signal
