Sounds in games have obvious effects to the atmosphere of the game, and can make or break the gaming experience. Therefore, the commands in Leadwerks Engine 2 allow complete access to sounds, including modifying the sounds with EAX effects. Listener entities tell the engine how to spatialize 3D sounds. Although you can create as many listeners as you want, only one will be used by the engine. Hiding a listener will disable it. You should make sure you only have one unhidden listener entity at any given time.
