VORRICHTUNG UND VERFAHREN ZUM ANALYSIEREN EINES AUDIO-INFORMATIONSSIGNALS

摘要

For analyzing an information signal consisting of a superposition of partial signals, wherein a partial signal originates from an individual source, the information signal is first decomposed into several component signals. Then one or more features are calculated for each component signal, wherein the feature(s) is/are defined so that it/they provide(s) a statement on an information content of the component signal. Finally, an association of the component signals with at least two subspaces is performed on the basis of the features calculated for the component signals. By feature extraction on the component signal level, an efficient subspace decomposition which is meaningful with respect to a present audio scene is achieved.
