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 at least to:
obtain a spatial audio signal comprising at least one audio signal and spatial metadata associated with the at least one audio signal;
obtain at least one data set related to binaural rendering;
obtain at least one pre-defined data set related to binaural rendering;
determine at least one combined data set comprising at least part of the at least one data set and at least part of the at least one pre-defined data set; and
generate a binaural audio signal based on a combination of at least part of:
the at least one combined data set;
the spatial metadata; and
the at least one audio signal.
