(Processing) Syncronizing video image with sound

One of my complaints about Flash is that it still can't capture wave forms of sound from sources like the microphone or line-in.

With processing, it's like taking candy from a baby.
Here is a sample to get audio input from your PC and use the sample data to a create visual effect on a video image.
I didn't uploaded the completed applet because it didin't seem to work on a web page(neither does the example on the Minim library's online documentation).
If run on a PC with web-cam and microphone, this example will show an image from the camera distorted according to the waveforms as you talk or sing.



import ddf.minim.*;
import processing.video.*;

Minim minim;
AudioInput in;
Capture cam;
 
void setup() {
  size(320, 240);
  cam = new Capture(this, width, height);
  minim = new Minim(this);
  minim.debugOn();
  in = minim.getLineIn(Minim.MONO, 512);
}
 
void draw() {
  drawImage();
}

void drawImage() {
  float lev;
  PImage img = createImage(width,height,RGB);
  int ty;
  if (cam.available() == true) {
    cam.read();
    cam.loadPixels();
  
     for (int i = 0; i < width; i ++) {
       lev = in.left.get(int(float(i) / width * 511)) * 60;
       for (int j = 0; j <height; j ++) {
    
       ty = int(j + lev);
       if (ty < 0) { ty += height; }
       if (ty >= height) { ty -= height; }
       img.pixels[i + j * width] = cam.pixels[i + ty * width];
     }
   }
   image(img, 0, 0);
  }
}

 
void stop() {
  in.close();
  minim.stop();
  super.stop();
}
