1. A method of rendering an Ambisonics audio signal, the method comprising:
receiving a set of L loudspeaker positions;
adding one or more virtual loudspeaker positions ΩL+1′ to the set of L loudspeaker positions to determine a new set of L2 loudspeaker positions;
determining a first decode matrix for the new set of L2 loudspeaker positions;
determining a second decode matrix for the set of L loudspeaker positions, wherein the second decode matrix is determined based on at least one coefficient of the first decode matrix, and wherein the second decode matrix is further based on weighting and distributing at least a coefficient for the one or more virtual loudspeaker positions ΩL+1′ based on a weighting factor
determining a rendering matrix based on a normalization of the second decode matrix, wherein the normalization is based on a frobenius norm; and
rendering the Ambisonics audio signal based on the rendering matrix.
