Abstract
Techniques of performing binaural rendering involve generating separate locations of virtual sources on the sphere for each ear of a listener. Along these lines, consider a set of actual audio sources that are not equidistant from a central point. To provide a listener with ambisonic audio, a sphere is defined with the listener at its center. When a source is not on the surface of the sphere, respective rays from the source to each of the listener's ears may not intersect the sphere at the same point. Rather, to provide a more accurate representation of the actual source, virtual loudspeakers are placed at each of the sphere intersections, a first virtual loudspeaker propagating audio to the left ear, a second virtual loudspeaker propagating audio to the right ear.
