Reverse playback,java

Question

I do need you help. How can I adjust the following code in order to play a .wav file backwards?

Any help will be very much appreciated..Thanks. Carlos

import java.io.*;
import javax.sound.sampled.*;

public class WavPlay {
   public static void main(String[] args) {
      SourceDataLine soundLine = null;
      int BUFFER_SIZE = 64*1024;  // 64 KB

      // Set up an audio input stream piped from the sound file.
      try {
         File soundFile = new File("chord.wav");
         AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundFile);
         AudioFormat audioFormat = audioInputStream.getFormat();
         DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);
         soundLine = (SourceDataLine) AudioSystem.getLine(info);
         soundLine.open(audioFormat);
         soundLine.start();
         System.out.println("File chord.wav....playing");
         int nBytesRead = 0;
         byte[] sampledData = new byte[BUFFER_SIZE];

         while (nBytesRead != -1) {
            nBytesRead = audioInputStream.read(sampledData, 0, sampledData.length);
            if (nBytesRead >= 0) {
               // Writes audio data to the mixer via this source data line.
               soundLine.write(sampledData, 0, nBytesRead);

            }

         }
      } catch (UnsupportedAudioFileException ex) {
         ex.printStackTrace();
      } catch (IOException ex) {
         ex.printStackTrace();
      } catch (LineUnavailableException ex) {
         ex.printStackTrace();
      } finally {
         soundLine.drain();
         soundLine.close();
      }
   }

}

Yes! It is possible, a long time ago I've made a bounty for it. Here is the link to my question. And the problem was that I had to find it out my own way.
