Parametric Multi-channel audio encoders, decoders, methods and computer programs for switching between multi-channel operation and individual-channel operation

摘要

A multi-channel audio encoder (100) is provided for providing an encoded audio representation (112) based on an input audio representation (110). The multi-channel audio encoder ( 100 ) is configured to switch between a parametric multi-channel encoding ( 120 ) of multiple channels and a separate encoding ( 130 ) of multiple channels according to characteristics of the input audio representation ( 110 ).
