+/**
+ * This class is a concrete implementation of AudioEngine3DL2 that uses the JOAL/OpenAL sound library to provide
+ * rendering of the Sound nodes in Java3D. <br>
+ * Notes: <br>
+ * 1. getChannelsAvailable, getNumberOfChannelsUsed and getTotalChannels have not been implemented yet and thus if you
+ * try to play more sounds than the system has then they will not play. I am still trying to find out exactly how to
+ * implement these functions, possibly there is no limit when rendering sound using software rendering. Also at the
+ * moment I think I have limited the implementation to 64 sounds. <br>
+ * 2. This implementation only plays wav files. <br>
+ * 3. Other functions not implemented have the comment 'NOT IMPLEMENTED' in their respective JavaDoc comment, otherwise
+ * the function has been implemented. <br>
+ * 4. Webstart demos are available at http://www.dutchie.net/joal/default.htm <br>
+ * Usage: <br>
+ * 1. You must have the OpenAL drivers installed on your machine, these can be downloaded for Windows, MacOS, Linux at
+ * http://www.openal.org/downloads.html <br>
+ * 2. You must have JOAL installed which can be downloaded from https://joal.dev.java.net/ . This includes joal.zip and
+ * the native dll/so for your selected platform. <br>
+ * 3. To use in your application you simply use: <br>
+ * java -Dj3d.audiodevice=org.jdesktop.j3d.audioengines.joal.JOALMixer [your_application_class] and call
+ * viewer.createAudioDevice(); as normal.
