Claim 11:
12. A method for generating an audio output signal comprising one or more audio output channels, wherein the method comprises:
receiving an audio input signal comprising one or more audio object signals,
receiving loudness information indicating information on the loudness of the audio object signals which are mixed within the downmix signal and indicating information on the loudness of the one or more further by-pass audio object signals which are not mixed within the downmix signal, and
receiving rendering information indicating whether one or more of the audio object signals shall be amplified or attenuated,
receiving a downmix signal comprising one or more downmix channels as the audio input signal, wherein the one or more downmix channels comprise the audio object signals, and wherein the number of the one or more downmix channels is smaller than the number of the audio object signals,
receiving downmix information indicating how the audio object signals are mixed within the one or more downmix channels,
receiving one or more further by-pass audio object signals, wherein the one or more further by-pass audio object signals are not mixed within the downmix signal,
generating the one or more audio output channels of the audio output signal from the audio input signal depending on the downmix information, depending on the rendering information and depending on a loudness compensation, wherein the loudness compensation depends on the loudness of the audio object signals which are mixed within the downmix signal, and depends on the loudness of the one or more further by-pass audio object signals which are not mixed within the downmix signal.
