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 additional information for synthesis of a binaural audio signal. The invention also describes the corresponding parametric audio decoder, parametric audio coder, computer software and a binaural audio signal synthesis device.
EFFECT: high efficiency when using compressed intermediate state, which is provided during parametric audio encoding.
