Abstract
The present invention relates to a method for conditioning an audio signal subjected to lossy compression involving the transfer of an audio signal to a frequency spectrum in which energies of the audio signal are correlated with frequencies of the audio signal, ascertainment of the frequencies fof local amplitude maxima in the frequency spectrum, stipulation of a first selection criterion and preselection of the frequencies fof two directly successive local amplitude maxima stipulation of a second selection criterion and selection of preselected frequencies f, of two directly successive local amplitude maxima, generation of an audio filler signal (AFS) and conditioning of the audio signal by introducing the audio filler signal (AFS) into a frequency range between the frequencies f, so that the frequency range is filled with the audio filler signal (AFS) at least in sections, in particular completely.
