+    \brief defines the position and orientation of the person listening to a sound field
+    defined by a AudioEngine.
+
+    A AudioEngine can have exactly one listener, that defines the position and orientation
+    of the person listening to the sounds defined by the objects placed within the audio engine.
+
+    In most cases, the AudioListener should simply be a child of the Camera element in QtQuick3D.
+    This will ensure that the sound experience is aligned with the visual rendering of the scene.
