摘要： A decoder for generating an audio output signal having one or more audio output channels is provided. The decoder includes a receiving interface for receiving an audio input signal including a plurality of audio object signals, for receiving loudness information on the audio object signals, and for receiving rendering information indicating whether one or more of the audio object signals shall be amplified or attenuated. Moreover, the decoder includes a signal processor for generating the one or more audio output channels of the audio output signal. The signal processor is configured to determine a loudness compensation value depending on the loudness information and depending on the rendering information. Furthermore, the signal processor is configured to generate the one or more audio output channels of the audio output signal from the audio input signal depending on the rendering information and depending on the loudness compensation value. Moreover, an encoder is provided.

摘要： An apparatus for decoding an encoded audio signal to obtain modified output signals includes an input interface for receiving a transmitted downmix signal and parametric data relating to audio objects included in the transmitted downmix signal, the downmix signal being different from an encoder downmix signal, to which the parametric data is related; a downmix modifier for modifying the transmitted downmix signal using a downmix modification function, wherein the downmix modification is performed in such a way that a modified downmix signal is identical to the encoder downmix signal or is more similar to the encoder downmix signal compared to the transmitted downmix signal; an object renderer for rendering the audio objects using the modified downmix signal and the parametric data to obtain output signals; and an output signal modifier for modifying the output signals using an output signal modification function.

摘要： An apparatus for processing an encoded audio signal having a plurality of downmix signals associated with a plurality of input audio objects and object parameters E. The apparatus includes a grouper configured to group the downmix signals into groups of downmix signals associated with a set of input audio objects. The apparatus includes a processor configured to perform at least one processing step individually on the object parameters Ek of each set of input audio objects in order to provide group results. Further, there is a combiner configured to combine the group results or processed group results in order to provide a decoded audio signal. The grouper is configured to group the downmix signals so that each input audio object belongs to just one set of input audio objects. The invention also refers to a corresponding method.
