FIELD: audio data processing.
SUBSTANCE: in a bit stream, coefficient data is entered, which is the sign of entropy-encoded quantization indices, used further for entropy decoding of coefficient data from a bit stream using the selected code dictionary for creating a number of quantization indices. The code dictionary is selected from M predetermined code dictionaries, where the specified M predetermined code dictionaries were educated using accordingly the specified M predetermined implementations of pseudorandom noise, where the selected code dictionary is connected to the specified selected implementation of pseudorandom noise.
EFFECT: technical result is an increase in the performance of audio data processing.
