Abstract  Abstract

A device used for decoding audio signal containing code key signal and parametric data comprising a core decoder (600) used for encoding key signal to carry out decoding and obtain decoding key signal analyzer (602) before regeneration operation used for carrying out frequency at or after decoding key signal to carry out analysis to provide analysis result (603) and frequency regenerator (604) used for using frequency spectrum part of decoding key signal parameter data (605) and analysis result (603) for regeneration not including in the frequency spectrum part of decoding key signal.

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).
