Apparatus And Method For Processing An Encoded Audio Signal

Abstract: The invention refers to an apparatus for processing an encoded audio signal (100). The audio signal (100) comprises a sequence of access units (100") each access unit comprising a core signal (101) with a first spectral width and parameters describing a spectrum above the first spectral width. The apparatus comprises: a demultiplexer (1) for generating from an access unit (100") of the encoded audio signal (100) said core signal (101 ) and a set of said parameters (102) an upsampler (2) for upsampling said core signal (101 ) of said access unit (100") and outputting a first upsampled spectrum (103) and a timely consecutive second upsampled spectrum (103") the first upsampled spectrum (103) and the second upsampled spectrum (103") both having a same content as the core signal (101 ) and having a second spectral width being greater than the first spectral width of the core spectrum (101) a parameter converter (3) for converting parameters of said set of parameters (102) of said access unit (100") to obtain converted parameters (104 104") and a spectral gap filling processor (4) for processing said first upsampled spectrum (103) and said second upsampled spectrum (103") using said converted parameters (104). The invention also refers to a corresponding method.
