How to set volume of a SourceDataLine in Java

Question

I\'m trying to make an mp3 player in java and I can`t figure out how to control the volume in it.

I\'ve tried something like this:

         // Adjust         


        

Answer 1

 float vol=50;
final FloatControl volumeControl = (FloatControl) auline.getControl( FloatControl.Type.MASTER_GAIN );
volumeControl.setValue( 20.0f * (float) Math.log10( vol / 100.0 ) );

vol=0 means mute.
