May 18th, 2009, 8:08am  
Hello folks, I've problem using aiff or wav files within processing.

this is the sketch

     
Code:

// Example by Krister Olsson

import krister.Ess.*;

AudioChannel myChannel;
BandPass myBandPass;
Normalize myNormalize;

void setup() {
  size(256,200);

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

  // load "cell.aif" into a new AudioChannel
  myChannel=new AudioChannel("/home/mbutubuntu/Scrivania/vivaldi.wav");

  // apply a band pass filter
  myBandPass=new BandPass(960,-20,16);
  
  myBandPass.filter(myChannel);

  // normalize
  myNormalize=new Normalize();
  
  myNormalize.filter(myChannel);

  // play
  myChannel.play();
}

void draw() {
}

// we are done, clean up Ess

public void stop() {
  Ess.stop();
  super.stop();
}
