Claim 24:
25. A non-transitory digital storage medium having computer-readable code stored thereon to perform, when the computer-readable code is run by a computer, a method of encoding an audio signal, the method comprising:
core encoding first audio data of the audio signal in a first spectral band to obtain a core-encoded audio signal for the first spectral band;
parametrically coding second audio data of the audio signal in a second spectral band being different from the first spectral band, wherein the parametrically coding comprises:
analyzing the first audio data in the first spectral band to acquire a first analysis result and analyzing the second audio data in the second spectral band to acquire a second analysis result, wherein the second spectral band is different from the first spectral band;
calculating a compensation value using the first analysis result and the second analysis result; and
calculating a parameter from the second audio data in the second spectral band using the compensation value,

and
outputting the encoded audio signal, the encoded audio signal comprising the core-encoded audio data for the first spectral band and the parameter calculated from the second audio data in the second spectral band using the compensation value.
