PROBLEM TO BE SOLVED: To generate almost natural reverberation, of which the frequency rises with time by hand clapping in a room or a passageway with a small calculation quantity. SOLUTION: Dimensions Lx, Ly, and Lz and an acoustic velocity c are inputted (S1), and Lm=√((Lx2+Ly2+Lz2)/3) is obtained (S2), and further, α=Lm/c is obtained (S3), and a series of an integer M increment one by one (S5); and if M≠4k(8m+7) holds (S6), √M is calculated (S7), and further, α√M is obtained (S8), and an impulse is generated at the time of α√M (S10). |
