This is basically an audio input that generates shapes based on frequency...
Been getting these errors with previously functioning processing projects: line unsupported: interface TargetDataLine supporting format PCM_SIGNED 44100.0 Hz... I believe it used to work on a previous version of processing, so did some of my code get obsolete? Error is on line 42

Code:

import krister.Ess.*;

int bufferSize;
int steps;
float limitDiff;
int numAverages=32;
float myDamp=.1f;
float maxLimit,minLimit;

FFT myFFT;
AudioInput myInput;

void setup () {
  size(800,600);

  // start up Ess
  Ess.start(this);  

  // set up our AudioInput
  bufferSize=512;
  myInput=new AudioInput(bufferSize);

  // set up our FFT
  myFFT=new FFT(bufferSize*2);
  myFFT.equalizer(true);

  // set up our FFT normalization/dampening
  minLimit=.005;
  maxLimit=.05;
  myFFT.limits(minLimit,maxLimit);
  myFFT.damp(myDamp);
  myFFT.averages(numAverages);

  // get the number of bins per average 
  steps=bufferSize/numAverages;

  // get the distance of travel between minimum and maximum limits
  limitDiff=maxLimit-minLimit;

  frameRate(25);         

  myInput.start();
}

void draw() {
   //rotate(90);
  background(0);
  colorMode(HSB, 400);
  smooth();
 //line(0,500,50,-myFFT.spectrum[5]*500);

 for (int i=0; i<bufferSize; i+=10) {
    //pushMatrix();
    
   int mycolor= round(myFFT.spectrum[i]*2000);
    noStroke();
    fill(mycolor-200,250,mycolor);
    println("mycolor is equal to "+mycolor);
    for(int y=1; y<=40; y+=2){
      
       ellipse(2*i, y*20, 70-mycolor/15, 70-mycolor/15); 
    }
   
    //scale(1.1);
   // rotate(.4);
    //popMatrix();
    
//    }
  }
