FIELD: physics.
SUBSTANCE: invention relates to means for decoding an encoded audio signal. An apparatus for decoding an encoded audio signal comprising an encoded core signal and parametric data comprises: a core decoder for decoding the encoded core signal, to obtain a decoded core signal; an analyser for analysing the decoded core signal before or after performing a frequency regeneration operation, to provide an analysis result; and a frequency regenerator for reproducing the spectral portions not included in the decoded core signal, using a spectral portion of the decoded core signal, the parametric data, and the analysis result.
EFFECT: technical result is to improve the quality of the decoded audio signal.
