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

摘要

An apparatus for encoding a directional audio coding parameter including a spreading parameter and a directional parameter comprises: a parameter calculator 100 for calculating a spreading parameter at a first time or frequency resolution and a directional parameter at a second time or frequency resolution; And a quantizer and encoder processor 200 for generating quantized and encoded representations of the spreading parameters and direction parameters.
