Class | public class Sound3D |
Inheritance | Sound3D ObjectContainer3D Object3D flash.events.EventDispatcher |
A sound source/emitter object that can be positioned in 3D space, and from which all audio playback will be transformed to simulate orientation.
The Sound3D object works much in the same fashion as primitives, lights and cameras, in that it can be added to a scene and positioned therein. It is the main object, in the 3D sound API, which the programmer will interact with.
Actual sound transformation is performed by a driver object, which is defined at the time of creation by the driver ini variable, the default being a simple pan/volume driver.
