METHOD FOR SIGNAL PROCESSING, ENCODING APPARATUS THEREOF, AND DECODING APPARATUS THEREOF

摘要

PURPOSE: A signal processing method, an encoding device therefor, and a decoding device therefor are provided to prevent the degradation of signal quality generated in decoding. CONSTITUTION: An encoding device, performing down mixing to first and nth channel signals into a mono signal, generates a space parameter between a reference channel signal and the rest of signals among the first and nth channel signals(310). The encoding device transmits encodes the space parameter to transmit the same to a decoding device(320).
