Downmixer and method of downmixing
Downmixer and Method of Downmixing Abstract A downmixer 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 re...
