Qualche anima pia che mi spiega un po cosa fa questo metodo che non ho scritto io . Help meeeeee!!

package jCallRemember.libreria;


import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;
import java.io.File;
import java.io.IOException;
import javax.sound.sampled.UnsupportedAudioFileException;

public class WAVPlayer {


    private final int BUFFER_SIZE = 128000;
    private File soundFile;
    private AudioInputStream audioStream;
    private AudioFormat audioFormat;
    private SourceDataLine sourceLine;


    /**

     * @throws javax.sound.sampled.LineUnavailableException

     * @throws javax.sound.sampled.UnsupportedAudioFileException
     */
    public void playSound(String filename) throws LineUnavailableException, 
            IOException, UnsupportedAudioFileException {


        String strFilename = filename;


        soundFile = new File(strFilename);




        audioStream = AudioSystem.getAudioInputStream(soundFile);


        audioFormat = audioStream.getFormat();


        DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);


        sourceLine = (SourceDataLine) AudioSystem.getLine(info);
        sourceLine.open(audioFormat);


        sourceLine.start();


        int nBytesRead = 0;
        byte[] abData = new byte[BUFFER_SIZE];
        while (nBytesRead != -1) {


            nBytesRead = audioStream.read(abData, 0, abData.length);


            if (nBytesRead >= 0) {
                
                sourceLine.write(abData, 0, nBytesRead);
            }
        }


        sourceLine.drain();
        sourceLine.close();
    }


}

commentandomi magari un po i metodi.. lo so c'è la documentazione ... ma ahime non riesco a capire molto..
