PROBLEM TO BE SOLVED: To provide a sound signal processing unit that can flexibly cope with the number of reproduction speakers and their arrangement so as to reproduce reverberation and sound image localization in a measurement environment and improve the efficiency in the measurement environment. SOLUTION: A measuring speaker outputs a measured sound to measure an impulse response in a 1st closed surface in the measurement environment (S001), and a transfer function H is obtained on the basis of the measured impulse response (S002). A reproduction sound is outputted on the basis of a sound signal subjected to arithmetic processing on the basis of the transfer function H in a 1st closed surface in a reproduction environment (S003), the impulse response of the reproduction sound is measured in a 2nd closed surface (S004), and a transfer function G is obtained on the basis of the impulse response measured in the 2nd closed surface (S005). In the case of reproducing the sound in the reproduction environment, the reproduced sound reproduction signal is subjected to arithmetic processing on the basis of the transfer function G and the processed signal is outputted (S006). |
