    摘要： An apparatus for extracting a direct and/or ambience signal from a downmix signal and spatial parametric information, the downmix signal and the spatial parametric information representing a multi-channel audio signal having more channels than the downmix signal, wherein the spatial parametric information comprises inter-channel relations of the multi-channel audio signal, is described. The apparatus comprises a direct/ambience estimator and a direct/ambience extractor. The direct/ambience estimator is configured for estimating a level information of a direct portion and/or an ambient portion of the multi-channel audio signal based on the spatial parametric information. The direct/ambience extractor is configured for extracting a direct signal portion and/or an ambient signal portion from the downmix signal based on the estimated level information of the direct portion or the ambient portion.

    摘要： An apparatus for generating loudspeaker signals is provided. The apparatus comprises an object metadata processor (110) and an object renderer (120). The object renderer (120) is configured to receive an audio object. The object metadata processor (110) 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. The object metadata processor (110) 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. The object renderer (120) is configured to generate the loudspeaker signals depending on the audio object and depending on position information. The object metadata processor (110) is configured to feed the first position of the audio object as the position information into the object renderer (120), if the audio object is indicated in the metadata as being not screen-related. The object metadata processor (110) is configured to feed the second position of the audio object as the position information into the object renderer (120), if the audio object is indicated in the metadata as being screen-related.
