APPARATUS AND METHOD FOR EXTRACTING A DIRECT/AMBIENCE SIGNAL FROM A DOWNMIX SIGNAL AND SPATIAL PARAMETRIC INFORMATION. |
摘要 |
<p>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.</p> |
