Reference Signals
When creating signal generators yourself, you will want to compare your audio output to reference signals. Here are a few audio programing languages/environments that might be useful.
- [Chuck]-audio programming language
- [Pure Data]- a graphical audio programming language
- [SuperCollider]-audio programming language
SAMPLE CHUCK CODE
//** Comment/uncomment the different oscillators to hear each **//
SinOsc s => dac; //TriOsc s => dac; //SqrOsc s => dac; //PulseOsc s => dac;
.2 => s.gain;
while( true ) {
440.0 => s.freq; 100::ms => now;
}
//************ Use this for impulse ****************//
//Impulse i => dac; //while( true ) { // 1.0 => i.next; // 100::ms => now; //}
//*************** Use this for noise *********************//
//Noise n => dac; //.2 => n.gain; //while( true ) //{ // 100::ms => now; //}
Download and install. From there you'll need to create a small bit of code to make the same output signals.
