Abstract:
Placement of one or two placed virtual loudspeakers within a loudspeaker setup that includes a real loudspeakers is determined and vector base amplitude panning (VBAP) gains including the gains of the real loudspeakers and placed one or two virtual loudspeakers are also then determined. Gains of one or two placed virtual loudspeakers are redistributed to the real loudspeakers to ensure preservation of total energy. Real loudspeakers in the loudspeaker setup have redistributed gains of one or two placed virtual loudspeakers. Loudspeaker outputs are generated and transmitted to the real loudspeakers to be played back. When received audio content is ambisonics content, a predetermined grid is generated and HOA content is projected to the grid. Other aspects are also described.

Claim (Index 15):
The method of  claim 12 , wherein determining the placement of the one or two placed virtual loudspeakers within the loudspeaker setup, when the loudspeaker setup is the 3D setup, includes:\n forming the polyhedron with locations of the real loudspeakers in the loudspeaker setup, determining a centroid, wherein the centroid is the center of mass of the polyhedron, determining an anti-centroid, wherein the anti-centroid is an additive inverse of the centroid, wherein, when the centroid is at an origin, determining that no placement of the one or two placed virtual loudspeakers is needed in the loudspeaker setup, wherein, when the centroid is not at the origin,\n determining a line that includes the centroid and the anti-centroid, \n determining intersection points of the line and a unit sphere centered at the listening point, wherein one of the intersection points having a smallest distance to the anti-centroid is the placement of the one placed virtual loudspeaker.
