ABSTRACT:
Calculation is performed for sound paths112-1, 114-1along which sounds emitted from a sound emitting point104in an acoustic space102are reflected and delivered to a sound receiving point106. By the calculation, entering angles ⊖R1, ⊖R2by which the sound paths enter the front side106aof the sound receiving point106are obtained. Calculation is then performed to obtain angles by which respective speakers52C,52L,52R,52SR,52SL of a 5.1 surround system are arranged in a listening room, with the front side106aof the sound receiving point106centered thereon. Audio signals on the respective sound paths are distributed among channels for any two speakers. Consequently, sharp localization of sound images is achieved, requiring less calculation in simulating acoustic characteristics of the acoustic space102in which the sound emitting point104for emitting sounds and the sound receiving point106for receiving the sounds are placed.
