#23 Add ability to turn sound and music on/off and change volume

[Nigel Gay]

This isn't technically possible at the moment with the library that I'm using, but wanted to log it at least.

JLayer is really dated, but here are the last Contacts:

Open Source Project
Last Update : 11/28/2004

The JLayer project has been launched on February 1999. The goal is to provide a Java™ - real time - MP3 decoder library. JLayerME sub-project has been launched on April 2002, it's the J2ME-oriented version of JLayer.

Both JLayer and JLayerME are licensed under LGPL.

MP3SPI is a Java plugin, based on JLayer, that adds MP3 support to the Java platform. jlGui is a graphical music player (WinAmp clone). It focuses on the sound capabilities of Java and it relies on MP3SPI for MP3 support.

The JLayer project is volunteer-driven. We don't have any specific requirement for volunteers other than willingness to really contribute while following the projects goal. Anyone wanting to join the development effort should send an email to jlayer@javazoom.net where all development efforts are coordinated.

If you're using the Java Sound API, you can set the volume with the MASTER_GAIN control.

import javax.sound.sampled.*;

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(
new File("some_file.wav"));
Clip clip = AudioSystem.getClip();
clip.open(audioInputStream);
FloatControl gainControl =
(FloatControl) clip.getControl(FloatControl.Type.MASTER_GAIN);
gainControl.setValue(-10.0f); // Reduce volume by 10 decibels.
clip.start();

I guess it's harder than one would first think...

Now, since Win7/Vista MS "fixed" some of the basics, but really not an issue because the game volume should be relative to the PC master volume anyways, if not here's a work-around when running the game...
