-			This uses the [link:https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API Web Audio API].
-
+			The [name] represents a virtual [link:https://developer.mozilla.org/de/docs/Web/API/AudioListener listener] of the all positional and non-positional audio effects in the scene.</br>
+			A three.js application usually creates a single instance of [name]. It is a mandatory construtor parameter for audios entities like [page:Audio Audio] and [page:PositionalAudio PositionalAudio].</br>
+			In most cases, the listener object is a child of the camera. So the 3D transformation of the camera represents the 3D transformation of the listener.
