Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    DataLine.Info info = null;//w  ww  . j  a v a2  s.  c  o  m
    Clip clip = (Clip) AudioSystem.getLine(info);

    FloatControl gainControl = (FloatControl) clip.getControl(FloatControl.Type.MASTER_GAIN);
    double gain = .5D; // number between 0 and 1 (loudest)
    float dB = (float) (Math.log(gain) / Math.log(10.0) * 20.0);
    gainControl.setValue(dB);

    BooleanControl muteControl = (BooleanControl) clip.getControl(BooleanControl.Type.MUTE);
