Just trying to do something that should be rather simple but I'm having a hell of a time getting it to function. I have 7 days before it needs to be displayed. I am trying to have smoke be pushed around by sound. Basically, have the input for the Particle System change from the mouse to the  microphone.  I have the sets of code that I want to blend. I know this is vague but anything will help.

SET ONE:::: The Particle system
import traer.physics.*;
//import processing.pdf.*;
//import pitaru.sonia_v2_9.*;

Particle mouse, b, c;
Particle[] others;
ParticleSystem physics;

PImage img;

void setup()
{
 size( 500, 500 );
 frameRate( 24 );
 cursor( CROSS );
 
 // sprite mask thing stolen from dan shiffman
 PImage msk = loadImage("texture.gif");
 img = new PImage( msk.width, msk.height );
 for ( int i = 0; i < img.pixels.length; i++ )
   img.pixels[i] = color(255);
 img.mask(msk);
 imageMode(CORNER);
 tint( 0, 225 );
 
 physics = new ParticleSystem( 0, 0.1 );
 mouse = physics.makeParticle();
 mouse.makeFixed();
 
 others = new Particle[1500];
 for ( int i = 0; i < others.length; i++ )
 {
   others[i] = physics.makeParticle( 1.0, random( 0, width ), random( 0, height ), 0 );
   physics.makeAttraction( mouse, others[i], 4000, 50 );
 }
}

void draw()
{
 mouse.moveTo( mouseX, mouseY, 0 );
 physics.tick();

 background( 245 );
 
 for ( int i = 0; i < others.length; i++ )
 {
    Particle p = others[i];
    image(img,p.position().x()-img.width/2,p.position().y()-img.height/2);
 }
}


SET TWO:::::: The Sound System
import processing.pdf.*;

import pitaru.sonia_v2_9.*;

int xpos = 5;
float a = 0.0;
float inc = PI/0.3;
float[]spectrum;
float x,y,px,py;

void setup(){
 size(1000,800);
 spectrum = new float[1024];
 Sonia.start(this);
 LiveInput.start(1024);
 ellipseMode(CENTER);
 colorMode(RGB, 256);
 smooth();
 background(255);
 
}

void draw(){
 
 getSpectrum();
 
}

void getSpectrum(){
 noStroke();
 spectrum = LiveInput.getSpectrum();
 float v = LiveInput.getLevel() * 10;
 for ( int i = 0; i < spectrum.length/4; i++){
   float r = (400.0/1000.0) * spectrum[i];
   float r1 = (400.0/1000.0) * spectrum[i+1];
   fill(i*5, xpos, 0,150);
   float w = (10.0/400.0) * r;
   ellipse((width/2)+sin(a)*xpos,(height/2)+cos(a)*xpos,w,w);
   inc = PI/r1;
   a += inc;
   xpos += r/100.0;
 }
 a = 0.0;
 xpos = 1;
}

void mousePressed(){
 background(255);
}

void keyPressed(){
 exit();
 
}

public void stop(){
 Sonia.stop();
 super.stop();


}

thx for ur link, lots of great examples in there.  your waves sketch was exactly what I was after to clear up some question marks on Additive Blending.

thx again!
