1. A multi-channel audio encoder for providing an encoded audio representation on the basis of an input audio representation,
wherein the multi-channel audio encoder is configured to switch between a parametric multi-channel encoding of a plurality of channels and an individual encoding of a plurality of channels in dependence on characteristics of the input audio representation;
wherein the multi-channel audio encoder is configured to determine whether there are interfering sources in the input audio representation and to switch in dependence on the determination.
