<P>PROBLEM TO BE SOLVED: To make it possible to reduce a structure or computation processing quantity necessary for computation and reproduce an appropriate sound when reproducing a stereophonic sound. <P>SOLUTION: Head-related transfer functions measured by using a dummy head are thinned within a limited number of samples, and the result is stored as a head-related transfer function database in a memory section 32. A processing section 33 extracts a transfer function at an indicated position of sound source from the limited number of samples of the head-related transfer functions within the stored head-related transfer function database. The input sound signal is multiplied by the extracted transfer function, and a sound signal with two channels is obtained by a calculation section 37 to create a binaural stereophonic sound. <P>COPYRIGHT: (C)2010,JPO&INPIT |
