Abstract:
A sound field generation system performing interaural correction on at least one input signal to generate a target reproduction sound field, comprising:at least two sound releasing units; two input lines through which the one input signal is supplied to the sound releasing units; a plurality of first band splitting units which are disposed in at least one of the two input lines, and which have different bands from each other; a plurality of delaying units which are disposed in the first band splitting units, respectively; a sound picking unit adapted to pick up sounds released from the sound releasing units, at listening positions corresponding to both ears; a plurality of second band splitting units adapted to band-split outputs of the sound picking units with the same bandwidths as those of the first band splitting units; a calculating unit adapted to calculate interaural correlation on a basis of band-split outputs from the second band splitting units; and a controlling unit adapted to control delaying amounts of the delaying units on a basis of a calculation result of the calculating unit.
