示例1: audioCB
void audioCB(AudioIOData& io){
while(io()){
if(tmr()){
if(cnt()){
modMode ^= true; // increment LFO type, switch mod mode when wraps
printf("\nMod mode: %s modulation\n", modMode? "Amp" : "Freq");
}
}
env.mod(mod.cosU()); // modulate modifier parameter with unipolar cosine wave
float s = 0.f; // initialize current sample to zero
switch(cnt.val){
// non-modifiable generators ordered from smooth to sharp:
case 0: s = env.cosU(); break; // unipolar cosine
case 1: s = env.hann(); break; // a computed hann window (inverted cosU)
case 2: s = env.triU(); break; // unipolar triangle
case 3: s = env.upU(); break; // unipolar upward ramp
case 4: s = env.downU(); break; // unipolar downward ramp
case 5: s = env.sqrU(); break; // unipolar square
// modifiable generator ordered from smooth to sharp:
case 6: s = env.pulseU(); break; // Mix between upward ramp and downward ramp
case 7: s = env.stairU(); break; // Mix between a square and impulse.
case 8: s = env.line2U(); break; // Mix between a ramp and a triangle
case 9: s = env.up2U(); break; // Mix between two ramps
}
if(modMode){ // amplitude modulate noise with envelope
s *= noise();
}
else{ // frequency modulate oscillator with envelope
osc.freq(s*400 + 200); // between 100 and 200 hz
s = osc.cos();
}
io.out(0) = io.out(1) = s*0.2;
}
