Claim 6:
7. The apparatus of claim 1,
wherein the spectral characteristics estimator is configured to calculate, as the spectral characteristic, a first spectral flatness measure of a spectrum of the first channel signal and a second spectral flatness measure of a second spectrum of the second channel signal, and
to determine the spectral characteristic of the spectrum from the first spectral flatness measure and the second spectral flatness measure by selecting a maximum value among the first and second spectral flatness measures, by determining a weighted average or an unweighted average between the first and second spectral flatness measures, or by selecting a minimum value among the first and second spectral flatness measures.
