APPARATUS AND METHOD FOR ENCODING AND DECODING METHOD DEVICE AND PROGRAM Russian patent published in 2016 - IPC G10L19/02 

FIELD: sound.

SUBSTANCE: invention relates to encoding apparatus and encoding method, decoding device and decoding method can be used to obtain high-quality audio. Encoding device includes a sub-band separation module, quasi-power calculation unit for sub-bands of high and low frequency, characteristic value calculation unit configured to calculate the number of areas to determine the number of continuous sections of the frame, for which the same factor assessment is selected, selection module multiples the frame included in the composition portion of continuous frames, encoding module low frequency signal input, a multiplexing unit for generating an output code string. Decoding apparatus comprises an input string code data demultiplexing module for the selected coefficient estimation section frames.

EFFECT: technical result achieved - improving the quality of sound while reducing the amount of coding.
