摘要：
An apparatus for generating a decoded two-channel signal, comprises: an audio processor (802) for decoding an encoded two-channel signal to obtain a first set of first spectral portions; a parametric decoder (804) for providing parametric data for a second set of second spectral portions and a two-channel identification identifying either a first or a second different two-channel representation for the second spectral portions; and a frequency regenerator (806) for regenerating a second spectral portion depending on a first spectral portion of the first set of first spectral portions, the parametric data for the second portion and the two-channel identification for the second portion.
