Class AudioListener

java.lang.Object

com.codename1.media.audio.AudioListener

public final class AudioListener
extends Object

The position and orientation of the listener every PannerNode of a context is heard from, the Web Audio AudioListener. Get it with BaseAudioContext.getListener().

The coordinate system is right-handed: by default the listener is at the origin facing -Z, with +Y up and +X to the right. Every coordinate is an audio rate AudioParam, so a moving listener can be automated.
