Abstract
An apparatus (100) for generating spectral replacement values for an audio signal comprising: a buffer unit (110) for storing previous spectral values related to an error-free audio signal frame received previously, and a generator (120 ) of concealment frame to generate the spectral replacement values when a current audio signal frame has not been received or is erroneous, in which the error-free audio signal frame previously received comprises a filter information, having the filter associated filter information a filter stability value indicating a stability of a prediction filter defined by the filter information, and in which the concealment frame generator (120) is adapted to generate the spectral replacement values based on to the previous spectral values and based on the stability value of the filter.
