Processing Test Waveform + Image

RAW CODE

import ddf.minim.*;

Minim minim;
AudioPlayer song;
PImage img;

void setup()
{
 size(1800, 450);
//SOUND
 minim = new Minim(this);

 // this loads mysong.wav from the data folder
 song = minim.loadFile(“soltaste.mp3”);
 song = minim.loadFile(“soltaste2.mp3”);
 song.play();
 //END OF SOUND
 img = loadImage(“banner.jpg”);
}

void draw()
{
 //THE SAME IN ONE LINE background(img);
 image(img, 0, 0);

 //DRAW A WAVEFORM
 stroke(255);
 // we draw the waveform by connecting neighbor values with a line
 // we multiply each of the values by 50
 // because the values in the buffers are normalized
 // this means that they have values between -1 and 1.
 // If we don’t scale them up our waveform
 // will look more or less like a straight line.
 for(int i = 0; i < song.bufferSize() – 1; i++)
 {
   line(i, 50 + song.left.get(i)*50, i+1, 50 + song.left.get(i+1)*50);
   line(i, 150 + song.right.get(i)*50, i+1, 150 + song.right.get(i+1)*50);
   }
   //END OF DRAW WAVEFORM
  stroke(0);  
  for(int i = 0; i < song.bufferSize() – 1; i++)
 {
   line(i, 50 + song.left.get(i)*50, i+10, 50 + song.left.get(i+1)*50);
   line(i, 150 + song.right.get(i)*50, i+10, 150 + song.right.get(i+1)*50);
   }
  for(int i = 0; i < song.bufferSize() – 1; i++)
  bezier(i+120, 150 + song.left.get(i)*120, i+120, 150 + song.left.get(i+1)*120, i+10, 50 + song.left.get(i)*50, i+10, 50 + song.left.get(i+1)*50);

}

I’m using sound library minim applying a specific image and adding a bezier with random numbers to create shapes. The general prototype idea is to draw waveform of Mexican sounds on top of Mexico City either as image of a map or video of the city moving across us along with the moving waveform. Or a collection of all sound waveforms (tamales, basura, camotes, etc.) in a map to see how it will look like all waveforms in physical space.
*Song used for prototype is Me Soltaste by Jesse & Joy
