// Example by Krister Olsson

import krister.Ess.*;

AudioChannel myChannel;
PitchShift myPitchShift;

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

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

  // load "cell.aif" into a new AudioChannel
  myChannel=new AudioChannel("cell.aif");

  // shift pitch up by 3 semitones
  myPitchShift=new PitchShift(Ess.calcShift(3));
  
  myPitchShift.filter(myChannel);

  // play
  myChannel.play();
}

void draw() {
}

// we are done, clean up Ess

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

Parameters   ,
pitchshift   any instance of PitchShift

src   the source AudioChannel or AudioStream instance
srcArray   float[]: the source array containing sample data
rate   float: the sample rate of the source floating point array
dest   the destination AudioChannel or AudioStream or floating point array. The default is the source AudioChannel, AudioStream, or floating point array
wet   float: the wet/dry mix value, 0 being completely dry (all source) and 1 being completely wet (all filtered output)
offset  int: the sample frame from which to start filtering. The default is the first frame
frames   int: the number of frames to filter. The default is the entire AudioChannel, AudioStream, or floating point array
   
Returns   nothing
