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