An apparatus for generating loudspeaker signals, comprising: an object metadata processor, and an object renderer, wherein metadata comprises an indication on whether an audio object is dependent on a size of a screen, and further comprises 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 the size of the screen, if the audio object is indicated in the metadata as being dependent on the size of the screen, 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 dependent on the size of the screen, 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 dependent on the size of the screen, wherein the first position indicates a first azimuth, a first elevation and a first distance, wherein the second position indicates a second azimuth, a second elevation and a second distance, wherein the object metadata processor is configured to calculate the second position of the audio object depending on at least one of a first linear mapping function and a second linear mapping function, wherein the first linear mapping function is defined to map a first azimuth value to a second azimuth value, wherein the second linear mapping function is defined to map a first elevation value to a second elevation value. an object metadata processor, and an object renderer, wherein metadata comprises an indication on whether an audio object is dependent on a size of a screen, and further comprises 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 the size of the screen, if the audio object is indicated in the metadata as being dependent on the size of the screen, 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 dependent on the size of the screen, 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 dependent on the size of the screen, wherein the first position indicates a first azimuth, a first elevation and a first distance, wherein the second position indicates a second azimuth, a second elevation and a second distance, wherein the object metadata processor is configured to calculate the second position of the audio object depending on at least one of a first linear mapping function and a second linear mapping function, wherein the first linear mapping function is defined to map a first azimuth value to a second azimuth value, wherein the second linear mapping function is defined to map a first elevation value to a second elevation value.
