Abstract
There is inter alia disclosed an apparatus for spatial audio encoding configured to quantise and index a spatial audio direction parameter to form a quantised spatial audio direction index, wherein the spatial audio direction parameter is associated with a time sub frame of a frequency sub band of an audio frame; and determine a quantised spatial audio difference index by calculating the difference between the quantised spatial audio direction index and a quantised average spatial audio direction index.
