1. An apparatus for generating loudspeaker signals, comprising:
an object metadata processor, and
an object renderer,
wherein the object renderer is configured to receive an audio object,
wherein the object metadata processor is configured to receive metadata, comprising an indication on whether the audio object is screen-related, and further comprising a first position of the audio object,
wherein the object metadata processor is configured to calculate a second position of the audio object depending on the first position of the audio object and depending on a size of a screen if the audio object is indicated in the metadata as being screen-related,
wherein the object renderer is configured to generate the loudspeaker signals depending on the audio object and depending on position information,
wherein the object metadata processor is configured to feed the first position of the audio object as the position information into the object renderer if the audio object is indicated in the metadata as being not screen-related, and
wherein the object metadata processor is configured to feed the second position of the audio object as the position information into the object renderer if the audio object is indicated in the metadata as being screen-related.
