Package com.sun.j3d.audioengines

Class AudioEngineThread

  • All Implemented Interfaces:
    java.lang.Runnable
    public class AudioEngineThread
extends java.lang.Thread
    The Thread Class extended for Audio Device engines that must process calls dynamically, in 'real-time" to asynchronously change engine parameters.

    NOTE: this class is probably not needed for those Audio Device implementations that handle all dynamic parameters in the low-level audio library.
