FIELD: data processing.
SUBSTANCE: invention relates to bits allocation means. Number of bits for each of the plurality of sub-bands in the input spectrum frame in the form of fractions is estimated based on the allowable number of bits for the frame. Redistributed estimated number of bits in at least one sub-band, having number of bits greater than zero, until total number of bits for frame becomes equal to allowable number of bits for frame. Number of distributed bits for the sub-bands is equal to or greater than the predetermined minimum number of bits required for the sub-bands. Input spectrum has at least one of audio characteristics and speech characteristics.
EFFECT: high efficiency of bit allocation.
