Abstract:
An apparatus for generating an enhanced signal from an input signal, wherein the enhanced signal has spectral values for an enhancement spectral region, the spectral values for the enhancement spectral regions not being contained in the input signal, includes a mapper for mapping a source spectral region of the input signal to a target region in the enhancement spectral region, the source spectral region including a noise-filling region; and a noise filler configured for generating first noise values for the noise-filling region in the source spectral region of the input signal and for generating second noise values for a noise region in the target region, wherein the second noise values are decorrelated from the first noise values or for generating second noise values for a noise region in the target region, wherein the second noise values are decorrelated from first noise values in the source region.

Claim (Index 10):
The apparatus of  claim 1 ,\n wherein the mapper is configured to perform a gap filling operation for generating the target spectral region, the apparatus comprising: a spectral domain audio decoder 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 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 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 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.
