Abstract  Abstract

ABSTRACT The present invention discloses a method, and a decoder for processing audio signal, and pertains to the field of communications technologies. The method includes: obtaining a current SID, wherein the current SID comprises a noise low-band parameter and may comprise a noise high-band parameter; when the current SID does not comprise a noise high-band parameter, obtaining a CN frame based on a decoded noise low-band parameter and an extrapolated noise high-band parameter; or obtaining a second CN frame according to a decoded noise high-band parameter and a decoded noise low-band parameter. According to the present invention, different processing manners are used for the high-band signal and the low- band signal, calculation loads and encoded bits may be saved under a premise of not lowering subjective quality of a codec, and bits that are saved may help to achieve an objective of reducing a transmission bandwidth or improving overall encoding quality.
