Class AudioSource

java.lang.Object

de.jreality.scene.SceneGraphNode

de.jreality.scene.AudioSource

public abstract class AudioSource
extends SceneGraphNode

The core of audio for jReality. The basic idea is that a scene graph component can have an audio source attached to it. Audio renderers request mono sample readers from audio sources, one for each occurrence of the source in the scene graph. An audio source keeps track of time in terms of the number of samples requested so far. Readers can read samples concurrently, and sample requests are queued and managed so that an audio source only writes as many samples as the fastest renderer requests. Samples are floats in the range from -1 to 1.
