AudioListener

Remarks

One per mixer, and not one per camera. A split-screen game has two cameras and one set of speakers, and the answer to "which one does the audio follow" is a decision the game makes — usually a point between them — rather than something the mixer can average.

A value, published through the command queue. Fifty-two bytes cannot be written atomically, so a listener assigned directly from the game thread would be read torn by the audio thread — for one block, with a position from this frame and an orientation from the last one, which is a click. It goes through AudioEngine.SetListener instead.
