Audio reactive particles

In this recipe, we'll take a look at how we can create interesting audio reactive visuals. This sketch might be a good start, if you want to create your own software to do performances. This sketch is similar to the FFT example, but the visual output is a lot more interesting.

How to do it...

We'll start by importing the minim library and will declare a Minim object, an AudioPlayer object, and an FFT object. We also need an array to store our Particle objects and a boolean variable to use the fading effect or to draw a background in each frame. This is the code for the first part of the sketch.

import ddf.minim.*;
import ddf.minim.signals.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*;
  
Minim minim;
AudioPlayer player;
FFT fft;
  
Particle[] particles;
  
boolean fade = false;
  
void setup()
{
  size( 640, 480 );
  smooth();
  
  background( 0 );
    
  colorMode( HSB, 360, 100, 100, 100 );
  
  minim = new Minim( this );
    
  player = minim.loadFile...
