<P>PROBLEM TO BE SOLVED: To provide a technology capable of adjusting the sound quality such as a sense of reverberation and a sense of sound image localization or the like in reproducing a sound field under a measurement environment on the basis of transfer functions corresponding respectively to a plurality of positions on a first closed curve measured under a measurement environment other than the measurement environment. <P>SOLUTION: Reproduction signals corresponding respectively to a plurality of positions are generated by using a synthetic transfer function generated by summating transfer functions determined according to the plurality of positions to ordinary transfer functions on the basis of results of the measurement by directional measurement microphones located at the plurality of positions respectively at an instructed ratio to convolute the reproduction signals. Thus, the sound quality such as a sense of reverberation and a sense of sound image localization or the like can thereby be adjusted. <P>COPYRIGHT: (C)2010,JPO&INPIT |
