AUDIO DOWNMIXING

A down mixer for downmixing a multi-channel signal having at least two channels, comprises: a weighting value estimator (100) for estimating band-wise weighting values for the at least two channels; a spectral weighter (200) for weighting spectral domain representations of the at least two channels...

Zusammenfassung:	A down mixer for downmixing a multi-channel signal having at least two channels, comprises: a weighting value estimator (100) for estimating band-wise weighting values for the at least two channels; a spectral weighter (200) for weighting spectral domain representations of the at least two channels using the band-wise weighting values; a converter (300) for converting weighted spectral domain representations of the at least two channels into time representations of the at least two channels; and a mixer (400) for mixing the time representations of the at least two channels to obtain a downmix signal.
