原本的 order 是 based on Node's label

'[0]afifo[s0];[1]apad[s1];[s7]apad[s10];[s9][s10][s8][s1][2]amix=inputs=5:duration=first:dropout_transition=0:weights=0 0.25 1.0 1.0 1.0[s11];[s11]dynaudnorm=gausssize=3:maxgain=10[s12];[s0]asplit=outputs=3[s2#0][s2#1][s2#2];[s2#0]adelay=delays=4000:all=1[s3];[s2#1]adelay=delays=8000:all=1[s4];[s2#2]atrim=end=4.0[s5];[s3]atrim=end=8.0[s6];[s4]atrim=end=12.0[s7];[s5]apad[s8];[s6]apad[s9]'
