1. Apparatus for encoding directional audio coding parameters comprising diffuseness parameters and direction parameters, comprising:
a parameter calculator for calculating the diffuseness parameters with a first time or frequency resolution and for calculating the direction parameters with a second time or frequency resolution, wherein the second time or frequency resolution is different from the first time or frequency resolution; and
a quantizer and encoder processor for generating a quantized and encoded representation of the diffuseness parameters and the direction parameters.
