Apparatus And Method For Extracting A Direct/Ambience Signal From A Downmix Signal And Spatial Parametric Information
Abstract: 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.
