METHOD FOR BINARY ENCODING QUANTISATION INDICES OF SIGNAL ENVELOPE, METHOD OF DECODING SIGNAL ENVELOPE AND CORRESPONDING CODING AND DECODING MODULES Russian patent published in 2011 - IPC G10L19/02

Abstract RU 2420816 C2

FIELD: information technology.

SUBSTANCE: method for binary encoding a signal envelope comprises a variable length first coding mode which incorporates envelope saturation detection, and a second coding mode, executed in parallel with the first coding mode. One of the coding modes is selected as a function of a code length criterion and the result of detecting envelope saturation in the first coding mode.

EFFECT: high coding efficiency.
