Stereo pan in [-1, 1] for a source: -1 is hard left of the listener, 1 hard right, 0
directly ahead or behind. The listener's facing is its heading in radians (0 faces +x,
increasing clockwise on a screen where y grows downward), so turning the listener turns
what counts as "right" with it - a sound to the world's east is centred when the listener
faces east and hard right when the listener faces north.
A game with a stereo backend applies this itself; the framework has no panner node of its
own, so it reports the number rather than pretending to pan.
