Abstract:
An apparatus for decoding an encoded audio signal having an encoded representation of a first set of first spectral portions and an encoded representation of parametric data indicating spectral energies for a second set of second spectral portions, has: an audio decoder for decoding the encoded representation of the first set of the first spectral portions to obtain a first set of first spectral portions and for decoding the encoded representation of the parametric data to obtain a decoded parametric data for the second set of second spectral portions indicating, for individual reconstruction bands, individual energies; a frequency regenerator for reconstructing spectral values in a reconstruction band having a second spectral portion using a first spectral portion of the first set of the first spectral portions and an individual energy for the reconstruction band, the reconstruction band having a first spectral portion and the second spectral portion.

Claim (Index 1):
An audio encoder for generating an encoded audio signal, comprising:\n a time-spectrum converter configured for converting an audio signal into a spectral representation; a spectral analyzer configured for analyzing the spectral representation of the audio signal in order to determine a first set of first spectral portions to be encoded with a first spectral resolution and a second set of second spectral portions to be encoded with a second spectral resolution, the second spectral resolution being lower than the first spectral resolution; a parameter calculator configured for providing an energy information for a reconstruction band comprising spectral values of a first spectral portion and comprising a second spectral portion; and an audio encoder configured for generating a first encoded representation of the first set of the first spectral portions comprising the first spectral resolution, wherein the audio encoder is configured for providing scale factors for scale factor bands, wherein the first encoded representation comprises the scale factors; and wherein the parameter calculator is configured for generating a second encoded representation of the second set of second spectral portions, the second encoded representation comprising the energy information for the reconstruction band, wherein the reconstruction band coincides with a scale factor band or a group of scale factor bands, and wherein the first encoded representation comprises a scale factor for the scale factor band comprised in the reconstruction band.
