 // PannerNode 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.
