Apparatus and method for decomposing an input signal using a pre-calculated reference curve

摘要

An apparatus for decomposing a signal having an number of at least three channels includes an analyzer for analyzing a similarity between two channels of an analysis signal related to the signal having at least two analysis channels, wherein the analyzer is configured for using a pre-calculated frequency dependent similarity curve as a reference curve to determine the analysis result. The signal processor processes the analysis signal or a signal derived from the analysis signal or a signal, from which the analysis signal is derived using the analysis result to obtain a decomposed signal.

1. An apparatus for decomposing a signal comprising a plurality of channels, comprising:
an analyzer for analyzing a similarity between two channels of an analysis signal related to the signal comprising the plurality of channels to acquire an analysis result, wherein the analyzer is configured for using a pre-calculated frequency-dependent similarity curve as a reference curve to determine the analysis result, wherein the pre-calculated frequency-dependent similarity curve has been calculated based on two signals to acquire a quantitative degree of similarity between the two signals over a frequency range; and a signal processor for processing the analysis signal or a signal derived from the analysis signal or a signal, from which the analysis signal is derived, using the analysis result to acquire a decomposed signal.
