Claim 3:
4. The apparatus of claim 1,
wherein the mapper is configured to perform a gap filling operation for generating the target region, the apparatus comprising:
a spectral domain audio decoder configured for generating a first decoded representation of a first set of first spectral portions, the decoded representation comprising a first spectral resolution;
a parametric decoder configured for generating a second decoded representation of a second set of second spectral portions comprising a second spectral resolution being lower than the first spectral resolution;
a frequency regenerator configured for regenerating a reconstructed second spectral portion comprising the first spectral resolution using a first spectral portion and spectral envelope information for the second spectral portion; and
a spectrum time converter configured for converting the first decoded representation in the reconstructed second spectral portion into a time representation,

wherein the mapper and the noise filler are at least partly comprised in the frequency regenerator.
