Binaural Location goes beyond the simple pan control; it allows you to place your audio at a specific location anywhere in a virtual space around the listener. The location of the L and R control points on the screen controls the location of two virtual speakers. Based on the angle and distance from the speakers to the listener's ears, the app creates a realistic impression that the sound is actually coming from the specific location of the L and R points.
