FIELD: information technology.
SUBSTANCE: method for synthesis of binaural audio signals includes input of a parametrically encoded audio signal which contains at least one composite signal of a set of audio channels and one or more corresponding sets of additional information describing a multi-channel audio signal; and application of a predetermined set of filters with head transfer functions to at least one composite signal in a proportion defined by said corresponding set of values of amplification estimates for synthesis of a binaural audio signal.
EFFECT: improved use of compressed intermediate state, which is provided in parametric audio encoding, thereby improving efficiency during transmission and storage of the audio signal.
