<P>PROBLEM TO BE SOLVED: To reproduce a sound close to an original sound at the position of a listener by branching an acoustic signal of at least one channel out of acoustic signals of three or more channels and adding a branch signal thus produced to the acoustic signal of other channel. <P>SOLUTION: Out of at least three acoustic signals generated by an acoustic signal generating means, at least one acoustic signal is branched at a branch stage to take out a branch signal which is then added, at a summing stage, to an acoustic signal other than that branched at the branch stage. Based on the distance between the reproduction position of an acoustic signal from which a branch signal is taken out at the branch stage, and the reproduction position of an acoustic signal added with the branch signal at the summing stage, the branch signal is delayed at a processing stage and the level of the branch signal is adjusted in the acoustic processor. <P>COPYRIGHT: (C)2007,JPO&INPIT |
