FIELD: information technology.
SUBSTANCE: decoding method involves extraction of a set of encoded signals from an input bit stream, determination of which method from a set of decoding methods is to be used to decode each of the encoded signals, decoding the encoded signals using defined decoding methods and synthesising the decoded signals. Accordingly, signals having different characteristics can be encoded with optimum bit rate by attributing the said signals to one or more classes in accordance with characteristics of these signals and encoding each of the signals using the encoding unit which best suits the class to which the corresponding signal belongs.
EFFECT: efficient encoding of different signals, including audio and speech signals.
