An apparatus for decomposing an input signal having a number of at least three input channels comprises a downmixer (12) for downmixing the input signal to obtain a downmixed signal having a smaller number of channels. Furthermore, an analyzer (16) for analyzing the downmixed signal to derive an analysis result is provided, and the analysis result 18 is forwarded to a signal processor (20) for processing the input signal or a signal derived from the input signal to obtain the decomposed signal (26). |
