Claim 6:
7. The audio decoding apparatus of claim 6, wherein the entropy decoder is adapted for decoding a sequence of symbols from the encoded audio stream based on the probability distribution derived from the coding context using a symbol alphabet comprising an escape symbol and group symbols corresponding to a set of available group indices, for deriving a preliminary tuple of spectral coefficients based on an available group index to which a group symbol of the sequence of symbols corresponds, and based on the element index, and for multiplying the preliminary tuple with a factor depending on a number of escape symbols in the sequence of symbols to acquire the tuple of spectral coefficients.
