Apparatus, method and computer program for decoding an encoded audio signal

摘要

Apparatus for decoding an encoded audio signal comprising an encoded core signal and parametric data, comprising: a core decoder (600) for decoding the encoded core signal to obtain a decoded core signal; an analyzer (602) for analyzing the decoded core signal before or after performing a frequency regeneration operation to provide an analysis result (603); and a frequency regenerator (604) for regenerating spectral portions not included in the decoded core signal using a spectral portion of the decoded core signal, the parametric data (605), and the analysis result (603).
