<P>PROBLEM TO BE SOLVED: To provide a three-dimensional panning apparatus which pans an acoustic signal three-dimensionally. <P>SOLUTION: The apparatus comprises a pre-panning acoustic signal reading means 11 to read the pre-panning acoustic signal s(t), a post-panning acoustic signal output means 12 to output the post-panning acoustic signal q(t), a conversion means 13 to convert the pre-panning acoustic signal s(t) into a frequency area pre-panning acoustic signal S(ω), a normal position information generating means 14 to generate the normal position information, an arrangement information storing means 15 to store the arrangement information of the post-panning acoustic signal output means 12, a frequency area post-panning acoustic signal generating means 16 to generate the frequency area post-panning acoustic signal Q(ω) having panned the frequency area pre-panning acoustic signal S(ω), based on the normal position information and the arrangement information, and an inversion means 17 to invert the frequency area post-panning acoustic signal Q(ω) into the post-panning acoustic signal q(t). <P>COPYRIGHT: (C)2007,JPO&INPIT |
