SPATIAL AUDIO RENDERING

Apparatuses, systems, methods, and computer programs enable spatial audio rendering that allows for six degrees of freedom of movement of a listener. The spatial audio comprises higher order ambisonic signals. An apparatus includes circuitry for generating audio signal content sets that provide spatial audio scenes; determining positions in which the spatial audio scenes are audible; and associating a subset of audio signal content sets with the determined positions such that a first subset of audio signal content sets is associated with a first position and a second subset of audio signal content sets is associated with a second position. When audio signal content is provided for rendering, the first subset of audio signal content sets is retrieved if the listener is at the first position and if the listener is at the second position the second subset of audio signal content sets is retrieved.
