Spherical harmonics can be used to encode the radiation patterns of individual sound objects in a manner compatible with the ambisonic 'B' format. This 'O' format enables the construction of more realistic sound objects for use within synthesised ambisonic soundfields, whilst maintaining the simplicity and ease of use of ambisonics. This paper examines extensions to basic 'O' format which allow much closer approximation of the changes in sound radiation caused by differing source-listener distances.
