Abstract
A space surrounding a sound source (S) which is set in a sound field ( ) to be reproduced is divided into sound source element regions (S to Sn), and a space surrounding a sound receiving point (R) is divided into sound receiving element regions (R to Rm). An impulse response when a sound radiated from the sound source (S) is emitted from one of the sound source element regions (S to Sn), passes through the sound field ( ), enters one of the sound receiving element regions (R to Rm), and then reaches the sound receiving point (R) is obtained for each of combinations of the sound source element regions (S to Sn) and the sound receiving element regions (R to Rm). A sound emitted from a real sound source (Sr) in an arbitrary real space ( ) is picked up by microphones (MC to MCn) placed correspondingly with the sound source element regions (S to Sn). In an FIR matrix circuit ( ), the pickup signals are respectively subjected to a convolution operation with impulse responses which are obtained for each of the sound source element regions (S to Sn) in corresponding directions.
