Method and apparatus for obtaining spectrum coefficients for a replacement frame of an audio signal, audio decoder, audio receiver, and system for transmitting audio signals

An apparatus for acquiring spectrum coefficients for a replacement frame m of an audio signal, the apparatus comprising:

• a detector configured to detect a tonal component of a spectrum of an audio signal based on a peak that exists in the spectra of a last frame m−1 preceding a replacement frame m and a second to last frame m−2 preceding the replacement frame m;
• and
• a predictor configured to predict for the tonal component of the spectrum the spectrum coefficients for the peak and its surrounding in the spectrum of the replacement frame m;
• wherein for the non-tonal component of the spectrum a non-predicted spectrum coefficient for the replacement frame m or a corresponding spectrum coefficient of a frame preceding the replacement frame m is used.
