Abstract

An apparatus for encoding one or more audio objects to obtain an encoded signal is provided. The apparatus includes a for downmixing the one or more audio objects to obtain one or more unprocessed downmix signals. Moreover, the apparatus includes a processing module and a signal calculator. The signal calculator is configured to calculate each of one or more additional signals based on a difference between one of one or more processed downmix signals and one of the one or more unprocessed downmix signals. Moreover, the apparatus includes an object information generator. Furthermore, the apparatus includes an output interface for outputting the encoded signal. Moreover, a corresponding apparatus for decoding is provided.
