摘要
An apparatus for generating a stereo side signal having a first side channel and a second side channel from a stereo input signal having a first input channel and a second input channel is provided. The apparatus comprises a modification information generator (110) for generating modification information based on mid-side information. Furthermore, the apparatus comprises a signal manipulator (120) being adapted to manipulate the first input channel based on the modification information to obtain the first side channel and being adapted to manipulate the second input channel based on the modification information to obtain the second side channel. The modification information generator (110) comprises a spectral weights generator ( 116) for generating the modification information by generating a first spectral weighting factor based on a mono mid signal and on a mono side signal of the stereo input signal.
