Claim 1:
2. The audio encoding apparatus of claim 1, wherein the entropy encoder is adapted for encoding the result of the division or the tuple using a group index, the group index referring to a group of one or more codewords for which a probability distribution is based on the coding context, and, based on a uniform probability distribution, an element index in case the group comprises more than one codeword, the element index referring to a codeword within the group, and for encoding the number of divisions by a number of escape symbols, an escape symbol being a specific group index only used for indicating a division, and for encoding the remainders of the divisions based on a uniform probability distribution using an arithmetic coding rule.
