-// AudioPannerNode is an AudioNode with one input and one output.
-// It positions a sound in 3D space, with the exact effect dependent on the panning model.
-// It has a position and an orientation in 3D space which is relative to the position and orientation of the context's AudioListener.
-// A distance effect will attenuate the gain as the position moves away from the listener.
-// A cone effect will attenuate the gain as the orientation moves away from the listener.
-// All of these effects follow the OpenAL specification very closely.
