FIELD: physics.
SUBSTANCE: invention relates to means of encoding audio signals containing components of different nature. Bitstream signal is decoded as a preliminary temporary audio signal in one of several decoding modes. Post-filtering of the preliminary temporary audio signal is carried out by attenuating inter-harmonic noise, thereby obtaining a temporary audio signal, where attenuation of inter-harmonic noise is controlled by the post-filter gain. Absolute value of the gain is selectively assigned a zero value, whereby post-filtering is skipped, depending only on post-filtering information encoded in the bit-stream signal.
EFFECT: technical result consists in improvement of encoding quality of inhomogeneous audio signal.
