Patent ID: 8010373

Claim:
A decoding device for decoding an input signal (BS) containing an encoded dominant signal containing most signal energy, an encoded residual signal containing a remainder of the signal energy, and associated signal parameters, the device comprising: decoding means for decoding the encoded dominant signal and the encoded residual signal so as to produce a decoded dominant signal (m′ u ) and a decoded residual signal (s′ mod ) respectively; decorrelation means for deriving a synthetic residual signal (s′ syn ) from the decoded dominant signal (m′ u ); attenuation means for attenuating the synthetic residual signal (s′ syn ) so as to produce an attenuated synthetic residual signal (s′ syn,mod ); scaling means for scaling the decoded dominant signal (m′ u ) and the attenuated synthetic residual signal (s′ syn,mod ) so as to produce a reconstructed dominant signal (m′) and a scaled attenuated synthetic residual signal; combination means for combining the decoded residual signal (s′ mod ) and the scaled attenuated synthetic residual signal so as to produce a reconstructed residual signal (s′); and conversion means for converting the scaled decoded dominant signal (m′) and the reconstructed residual signal (s′) into a set of output signals (l′, r′) using signal parameters (IID′, ICC′), wherein the attenuation means ( 29 ) are arranged for being controlled by the decoded residual signal (s′ mod ).
