1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to:
obtain spatial audio and associated one or more three-dimensional parameters, wherein the one or more three-dimensional parameters comprise one or more direction parameters;
determine one or more ranges for direction parameters when the one or more three-dimensional parameters are reduced to two dimensions to obtain one or more two-dimensional parameters; and
apply processing to the one or more two-dimensional parameters based on whether or not the one or more ranges in two dimensions are in accordance with one or more criteria.
