Hello,

I'm working on my sound visual coding and at the moment it looks like waves of sound

and i want to make it look like a mosaic like that:



or similar, so the idea is to insert black colour values rather than waves fluctuations: black=no fluctuation(silence), white=high volume.

please help to adjust my existing coding to do that.

1. import ddf.minim.*;
   // import processing.opengl.*;
   AudioPlayer track;
   Minim minim;
   float bpm = 50.2;
   float mspb = 60000/bpm;
   float x = 0;
   float y = 0;
   float x1 =0;
   float x2 =0;
   float y2 =0;
   float y1 =0;
   //
   float horizontal_scaling = 180; // or 160
   float line_height = 1;
   int time = 0;
   //
   //
   void setup()
   {
     size(750, 500);
     background(0);
     stroke(255);
     smooth();
     minim = new Minim(this);
     track = minim.loadFile("test.mp3", 2048);
     track.loop();
   }
   //
   //
   void draw()
   {
     int lapse = millis() - time;
     //
     for (int i = 0; i < track.left.size()-1; i++)
     {
       float column_norm = line_height/1*(0+1.5*y);
       x1 = x     / horizontal_scaling;
       x2 = (x+1) / horizontal_scaling;
       y1 = track.left.get(i)  *line_height/2 + (column_norm);
       y2 = track.left.get(i+1)*line_height/2 + (column_norm);
       line(x1, y1, x2, y2);
       x++;
     } // for
     //
     if (lapse > mspb)
     {
       // start a new line on the left
       time = millis();
       y += 2; // or 1
       x = 0;
       if (y2 > height-40)
       {
         // start a new page from top
         y = 0;
         background(0);
       } // if
     } // if
   } // func
   //
   //
   void stop()
   {
     // always close Minim audio classes when you are done with them
     track.close();
     minim.stop();
     super.stop();
   }
   //
   
   

I hope it it possible.

Thanks
