Performance

asig -- input signal

kfreq -- the lower end of the harmonics created.

kceil -- the upper end of the harmonics created.

kharmonics -- amount of harmonics in the range 0.1 - 10.

kblend -- blend between 2nd and 3rd order harmonics in the range -10 - +10.

instr 1 ; excited sound + original sound

a1 diskin2 "Mathews.wav", 1, 3.5
a2 exciter a1, 3000, 20000, 10, 10	;generate uneven harmonics at maximum setting
     outs a2+a1, a2+a1
endin

instr 2 ; original sound for comparison

a1 diskin2 "Mathews.wav", 1, 3.5
   outs a1, a1
endin

instr 3 ; the effect of the excited sound only

a1 diskin2 "Mathews.wav", 1, 3.5
a2 exciter a1, 3000, 20000, 10, 10	;generate uneven harmonics at maximum setting
   outs a2, a2
