Usage

From source file:Main.java

public void playSound(final String filename) throws Exception {
    InputStream audioSrc = this.getClass().getResourceAsStream(filename);

    InputStream bufferedIn = new BufferedInputStream(audioSrc);
    audioStream = AudioSystem.getAudioInputStream(bufferedIn);

    audioFormat = audioStream.getFormat();

    DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);
    sourceLine = (SourceDataLine) AudioSystem.getLine(info);
    sourceLine.open(audioFormat);/* w ww  . j a  va 2  s  . c  o  m*/

    sourceLine.start();
    running = true;

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