Apparatus and method for encoding or decoding directional audio coding parameters using different time/frequency resolutions

摘要

An apparatus for encoding directional audio coding parameters comprising diffuseness parameters and direction parameters, comprises: a parameter calculator (100) 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; and a quantizer and encoder processor (200) for generating a quantized and encoded representation of the diffuseness parameters and the direction parameters.
