Abstract  Abstract

FIELD: acoustics.SUBSTANCE: invention relates to audio encoding. Audio decoder includes an arithmetic decoder to provide a plurality of decoded spectral values based on an arithmetically encoded representation of spectral values; and frequency-domain converter to time domain; arithmetic decoder is configured to select a mapping rule describing mapping of a code value arithmetically encoded display on a symbol code which displays one or more decoded spectral value or at least part of one or more of decoded spectral values depending on state of context; arithmetic decoder is configured to determine numeric current context value describing state of current context depending on a plurality of previously decoded spectral values as well as depending on where there is a spectral value to decode-in first preset frequency domain or in second preset frequency domain.EFFECT: technical result consists in improvement of efficiency of encoding at low computational costs.17 cl 48 dwg
