摘要：
A decoder for generating an audio output signal comprising one or more audio output channels is provided. The decoder comprises a receiving interface (110) for receiving an audio input signal comprising 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 comprises a signal processor (120) for generating the one or more audio output channels of the audio output signal. The signal processor (120) is configured to determine a loudness compensation value depending on the loudness information and depending on the rendering information. Furthermore, the signal processor (120) 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.
