Claim Text:
1. A decoding system configured to reconstruct an n-channel audio signal on the basis of a bitstream, the decoding system comprising: a parametric-mode demultiplexer for receiving the bitstream and outputting, based thereon and in a parametric coding mode of the system, an encoded core signal and multichannel coding parameters; a core signal decoder for receiving the encoded core signal and outputting, based thereon, an m-channel core signal, where 1≦m<n; and a parametric synthesis stage for receiving the core signal and the multichannel coding parameters and outputting, based thereon, the n-channel signal, wherein the parametric-mode demultiplexer is further configured to output, based on the bitstream, pre-processing dynamic range control, DRC, parameters quantifying an encoder-side dynamic range limiting of the core signal, and wherein the decoding system is operable to cancel the encoder-side dynamic range limiting based on the pre-processing DRC parameters.
