Abstract  Abstract

An audio decoder (200) for providing decoded audio information (212) based on the encoded audio information (210) may be configured based on an arithmetically encoded representation (222) of the spectral values. An arithmetic decoder (230) for providing a decoded spectral value of 232 and a time domain audio representation (262) using the decoded spectral value to obtain decoded audio information And a frequency domain time domain converter (260) for providing. The arithmetic decoder (230) is configured to select a mapping rule indicating a mapping of code values to symbol codes, depending on the context state. The arithmetic decoder is configured to determine or modify the current context state depending on the plurality of previously decoded spectral values. The arithmetic decoder detects a group of a plurality of previously decoded spectral values that meet a predetermined condition for their magnitude, individually or collectively, and depending on the result of the detection, the current context Configured to determine the state. Audio encoders use a similar principle. (Selection) Figure 2
