How To Get The Colors To Stay Transparent

lbrez16

Ok! So I have this code where I want to change the color of a photo based off of the input audio the code receives. I got it to do this, however, the biggest issue is that after saying a few words it changes to a solid color and stays that way. Does anyone know how to make it stay transparent? Help is appreciated! I'll post the code below.

import ddf.minim.*;
import ddf.minim.signals.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*;
PImage img;

Minim minim;
AudioInput in;

void setup()
{
    size( 540, 687 );
    img = loadImage("Ash.jpg");
    image(img,0,0);
    }

 {   
    minim = new Minim( this );

    in = minim.getLineIn( Minim.STEREO, 512 );
}

void draw()
{
      float p = 0;
    for ( int i = 0; i < in.bufferSize(); i++ ) {
        p += abs( in.mix.get( i ) ) * 1;
    }
  loadPixels();

    for (int i=0; i<(width*height); i++){
      float r = red(pixels[i]);
      float g = green(pixels[i]);
      float b = blue(pixels[i]);

      pixels[i] = color(r*p,g/p,b+p);

}
  updatePixels();
}

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

This is not a solution to your problem but an alternate code. Check it out.

Kf

import processing.sound.*;
Amplitude amp;
AudioIn in;
float ampt;
PImage photo;

void setup() {
  size(1200, 800);
  background(255);

  // Create an Input stream which is routed into the Amplitude analyzer
  amp = new Amplitude(this);
  in = new AudioIn(this, 0);
  in.start();
  amp.input(in);
  photo = loadImage("fig.jpg");
}      

void draw() {
  background(255);
  ampt = amp.analyze();
  println(ampt);

  float myColor = ampt*256; 
  tint((myColor), (myColor), (myColor));

  image(photo, 0, 0, width, height);
  loadPixels(); 
  int halfImage = width*height/2;
  for (int i = 0; i < halfImage; i++) {
    pixels[i+halfImage] = color(constrain((pixels[i]>>16)*round(random(ampt)*100),0,255) & 0xff,pixels[i]>>8 & 0xff,pixels[i]&0xff);
  }
  updatePixels();
}

Move line 14 to within your draw method.
