Description

Sound create use FM synthesis use C program. Use 0.60*expf( -time ) envelop. Algorithm 4 of YM2515 chip (not use chip, only follow its algorithm in C program) • No feed back • ampl_m1 = 0.627 • ampl_m2 = 0.627 • ampl_c1 = 0.798 • ampl_c2 = 0.798 • freq_m1 = 736.839 Hz • freq_m2 = 733.475 Hz • freq_c1 = 92.105 Hz • freq_c2 = 91.684 Hz • m1 = 0.0 • m2 = 0.0
