Left channel goes to left ear, right channel goes to right ear. Turn spatialiser off: select this to listen to the unprocessed audio channels. The audio might click slightly when you change between them: it’s a prototype and it’s free. The different reflection patterns and intensities are tuned to different kinds of content. If you want to experiment with the environments and speakers, start pressing other buttons. To configure it, click the little head tracker icon in the plug-in window (this does most the things that Bridgehead can do). Double-click on the animated head to zero it when you’re facing forwards.
