Abstract
A method is provided for the decoding of digital audio data, which is used to perform an error recognition dependent on transmitted reference values, e.g., scale factors. The method includes the comparison of reference values of a subband with preceding reference values of the same subband, in order to produce a characteristic that is compared with a threshold value, and that, if the characteristic is located above the predetermined threshold value, this is indicated by a signaling. In an example embodiment of the present invention, it is provided that in subbands in which no audio data are transmitted a default value is entered, which leads to the result that no characteristic is produced for this subband.
