Description

Sound create use FM synthesis use C program. Use expf( -4.0*time ) envelop. Algorithm 4 of YM2515 chip (not use chip, only follow its algorithm in C program) • no feedback • ampl_m1 = 304 • ampl_m2 = 232 • ampl_c1 = 136 • ampl_c2 = 127 • freq_m1 = 1056896*0.75 • freq_m2 = 527296*0.75 • freq_c1 = 2109184*0.75 • freq_c2 = 1056896*0.75
