Apparatus And Method For Encoding Or Decoding An Audio Signal With Intelligent Gap Filling In The Spectral Domain

Abstract: An apparatus for decoding an encoded audio signal, comprises a spectral domain audio decoder (112) for generating a first decoded representation of a first set of first spectral portions, the decoded representation having a first spectral resolution; a parametric decoder ( 114) for generating a second decoded representation of a second set of second spectral portions having a second spectral resolution being lower than the first spectral resolution; a frequency regenerator (116) for regenerating every constructed second spectral portion having the first spectral resolution using a first spectral portion and spectral envelope information for the second spectral portion; and a spectrum time converter ( 118) for converting the first decoded representation and the reconstructed second spectral portion into a time representation.
