Abstract  Abstract

An audio decoder (2200) for providing decoded audio information based on the encoded audio information includes a plurality of decoded spectra based on the arithmetically encoded representation (2222) of the spectral coefficients. An arithmetic decoder (2200) for providing the value (2224) is included. The audio decoder also uses a decoded spectral value (2224) to obtain a decoded audio information (2212) and a frequency domain time domain transformer (2230) for providing a time domain audio representation. including. The arithmetic decoder is configured to select a mapping rule indicating a mapping of code values to symbol codes, depending on a numerical current context value indicating a current context state. The arithmetic decoder is configured to determine a numerical current context value depending on the plurality of previously decoded spectral values. The arithmetic decoder evaluates at least one table using iterative interval size reduction and the numerical current context value is the same as the table context value indicated by the table entry or the table And is configured to obtain a mapping rule index value indicating the selected mapping table. The audio encoder also uses iterative interval table size reduction. (Selection) Figure 22
