Verfahren zum kaskadierten Codieren und Decodieren von Audiodaten

In a process for the cascaded coding and decoding of audio data, the spectral components of the short-term spectrum belonging to this data block is formed for each data block with a specific number of temporal input data, the encoded signal is formed from the spectral components for this data block using a psycho-acoustic model by controlling the bit distribution for the spectral components by means of quantization and coding, whereupon temporal output data are gained by decoding at the end of each codec stage. To avoid an impaired sound quality in codec cascades with several stages, an identification is added to the coded signal in an initial stage, said identification representing the beginning of the data block, whereby the following codec stages perform the distribution of each of the coded data blocks due to this identification.
