Abstract

The invention relates in general to the reproducing of multi-channel signals.
More particularly, the invention relates to the decoding of multi-channel audio signals representing multidimensional sound fields delivered by one or more delivery channels.
wherein the complexity of the decoding is roughly proportional to the number of channels used to present the decoded signal which may differ from the number of deliverer channels.
