hey all, im doing an art project but im new to code,
i need to make an ellipse start and expand each time a sound goes in pocessing
i already did the drawing based on a sketch from openprocessing, now i just need to make it start from sound and not from keypressed,

im using the minim library

here is my code:
4. ArrayList Circles = new ArrayList();
5. Circle D;
7. import ddf.minim.*; //minim audio input
8. Minim minim;
9. AudioInput in;
10. int s = 1700; // audio input sensivity
12. void setup(){
13. size(600,600);
14. smooth();
16. minim = new Minim(this);
17. minim.debugOn();
18. in = minim.getLineIn(Minim.MONO, 64);
20. }
22. void draw(){
23. background(0);
25. strokeWeight(3);
26. for (int i=0; i<Circles.size(); i++){
27. Circle D = (Circle) Circles.get(i);
28. D.run();
29. }
30. }
32. class Circle {
34. PVector pos;
35. color c;
36. float s;
37. int age;
39. Circle( PVector _pos, color _c, float _s ) {
40. pos = _pos;
41. c = _c;
42. s = _s;
43. }
45. void run() {
46. render();
47. age += 3;
48. if(age > 600) {
49. Circles.remove(this);
50. }
51. }
53. void render() {
54. stroke(255,255,255);
55. fill(255, 255, 255, 155-age*0.35);
56. ellipse( width/2, height/2, age*1.5, age*1.5 );
57. }
58. }
60. void keyPressed(){
63. Circle D = new Circle( new PVector(random(width), random(height)), color(100),0);
64. Circles.add(D);
65. }
70. void stop(){
71. in.close();
72. minim.stop();
73. super.stop();
74. }
thank you very much for your time!
i really apreciate all the help!
