FIELD: information technologies.
SUBSTANCE: invention discloses encoding of audio signal represented by corresponding set of signal selection values for each of multiple consequent segments. Signal selection values are analysed to determine one or more sinusoidal components from multiple consequent segments. Sinusoidal components are joined for multiple consequent segments to provide sinusoidal tracks. For each sinusoidal track, the phase is determined containing virtually monotonically varying value; and encoded audio flow is generated which flow comprises sinusoidal codes representing specified phase.
EFFECT: data decoding accuracy improvement.
