STEREO AUDIO SIGNAL ENCODER

摘要

An apparatus comprising: a channel analyser configured to determine at least one set of parameters defining a difference between at least two audio signal channels; a value analyser configured to analyse the at least one set of parameters to determine an initial trend; a mapper configured to map instances of the at least one set of parameters according to a first mapping to generate mapped instances with associated order position instances based on the initial trend; and an encoder configured to encode the mapped instances based on the order position of the mapped instances.
