Abstract
A method () for decoding an encoded audio signal () is described. The encoded audio signal () comprises a sequence of frames. Furthermore, the encoded audio signal () is indicative of a plurality of different dynamic range control (DRC) profiles for a corresponding plurality of different rendering modes. Different subsets of DRC profiles from the plurality of DRC profiles are comprised within different frames of the sequence of frames, such that two or more frames of the sequence of frames jointly comprise the plurality of DRC profiles. The method () comprises determining a first rendering mode from the plurality of different rendering modes; determining () one or more DRC profiles from a subset of DRC profiles comprised within a current frame of the sequence of frames; determining () whether at least one of the one or more DRC profiles is applicable to the first rendering mode; selecting () a default DRC profile as a current DRC profile, if none of the one or more DRC profiles is applicable to the first rendering mode; wherein definition data of the default DRC profile is known at a decoder () for decoding the encoded audio signal (); and decoding the current frame using the current DRC profile.
