Hi raymond,

if http://www.html5rocks.com/en/tutorials/webaudio/positional_audio/ i
found this description. "The sound plays at the normal volume inside the
inner angle and gradually changes gain to outer gain as you approach the
outer angle. Outside the outer angle the sound plays at outer gain." Does
this describe accuratly the expected behavior ?

It surely matches what i see. so my initial understanding, aka "when the
listener is "totally outside", im under the impression no sound should be
heard", was incorrect.
