Abstract  Abstract

Encoding and decoding and device and method for using time domain noise/mending shaping for coding audio signal comprising: frequency spectrum domain audio decoder (602) wherein the first decoding for generating the first group frequency spectrum part of the first expression the first decoding expression is forecast residual value frequency spectrum frequency regenerator (604) used for using the first group the frequency spectrum of the first part and the first part for generating reconsitution frequency spectrum and the second frequency spectrum part wherein the second frequency spectrum part reconsitution and in addition comprises frequency spectrum of forecast residual value and reverse forecast filter (606) for the use in the predict filter information comprises coding of frequency signal (607) using the first group the first frequency spectrum and the second frequency spectrum part reconsitution part of the frequency spectrum residual value for carrying out the reverse forecast on frequency.

An apparatus for decoding an encoded audio signal comprises: a spectral domain audio decoder (602) for generating a first decoded representation of a first set of first spectral portions being spectral prediction residual values; a frequency regenerator (604) for generating a reconstructed second spectral portion using a first spectral portion of the first set of first spectral portions wherein the reconstructed second spectral portion additionally comprises spectral prediction residual values; and an inverse prediction filter (606) for performing an inverse prediction over frequency using the spectral residual values for the first set of first spectral portions and the reconstructed second spectral portion using prediction filter information (607) included in the encoded audio signal.
