Abstract  Abstract

An apparatus for decoding an encoded audio signal comprising an encoded representation of a first set of first spectral portions and an encoded representation of parameter data representing information about spectral energies for a second set of second spectral portions, To decode the encoded representation of the parameter data to obtain decoded parameter data 902 for a second set of second spectral portions representing information on separate energies for the individual reconstructed bands, An audio decoder (900) for decoding an encoded representation (901b) of a first set of first spectral components to obtain a first set of first spectral components (904); The reconstruction band includes a first spectral portion 921 and a second spectral portion and is configured to reconstruct the second spectral portion 922 using the first spectral portion of the first set of first spectral portions, And a frequency regenerator 906 for recovering spectral values of the reconstruction band 920 including the frequency bands of the reconstructed bands 923 and 923, (912) the survivor energy information including the energy information that has been recovered and the additional spectral portions 922 and 923 use the first spectral portion 302 different from the first spectral portion 921, Tile energy spectra of the first spectral portion 921 having frequencies of the reconstructed band 920 and the additional spectral portions 922 and 923 of the reconstructed band 920 for different frequency values, A crystal 918, and; (914) determining loss energy information of the recovery band (920) using the survival energy information and the individual energy information for the recovery band; And adjust (916) additional spectral portions of the reconstruction band based on the tile energy information and the loss energy information.
