FIELD: physics.
SUBSTANCE: method is implemented by predicting the comfort noise that is generated by the decoder according to the currently input frame in the case, in which the currently input frame is encoded into a silence descriptor (SID) frame and by determining the actual silence signal. The currently input frame is a silence frame, determining the degree of deviation between the comfort noise and the actual silence signal, determining that the encoding method of the currently input frame is a coding technique with a tightening frame, according to the degree of deviation and coding the currently inputted frame according to the encoding technique with a snap frame.
EFFECT: expanding the arsenal of technical means for coding signals.
