Claim 13:
14. An apparatus for processing audio, the apparatus comprising:
a plurality of loudspeakers;
a processor; and
a memory,
wherein the processor is configured to control the apparatus to receive one or more audio objects, wherein each of the one or more audio objects respectively includes position information;
wherein for a given audio object of the one or more audio objects:
the processor is configured to control the apparatus to select, based on the position information of the given audio object, at least two renderers of a plurality of renderers;
the processor is configured to control the apparatus to determine, based on the position information of the given audio object, at least two weights;
the processor is configured to control the apparatus to render, based on the position information, the given audio object using the at least two renderers weighted according to the at least two weights, to generate a plurality of rendered signals; and
the processor is configured to control the apparatus to combine the plurality of rendered signals to generate a plurality of loudspeaker signals; and

wherein the processor is configured to control the apparatus to output, from the plurality of loudspeakers, the plurality of loudspeaker signals,
wherein the plurality of loudspeakers is arranged in a first group that is directed in a first direction and a second group that is directed in a second direction that differs from the first direction,
wherein the second direction includes a vertical component, wherein the at least two renderers include a wave field synthesis renderer, an upward firing panning renderer and a beamformer, and wherein the wave field synthesis renderer, the upward firing panning renderer and the beamformer generate the plurality of rendered signals for the second group.
