Detect sound, trigger sound
May 11th, 2010, 3:39am  
Hi! I want to detect sound with minim.getLineIn() and trigger random sounds from a list if the detected sound is loud enough. Can I get some help with this?

Current sollution (without random sample triggered):
 
for (int i = 0; i < 1; i++){
   float r = (1000*in.right.get(i));
   float l = (1000*in.left.get(i+1));
   float number = ((r*l)/2);
   //println(number);
   if ( number > 100) {
     q.trigger();
   //trigger AudioSample q
   }

It works for now, but I'm sure there are easier ways.

Hey you could use the amplitude follower part of this dumb pitch detector
