摘要：Embodiments of the present invention provide a signal classification methodand device, and encoding and decoding methods and devices. The encoding methodincludes: dividing a current frame into a low-frequency band signal and a high-frequencyband signal; attenuating the high-frequency band signal or a to-be-encoded characteristicparameter of the high-frequency band signal according to an energy attenuation value ofthe low-frequency band signal, where the energy attenuation value indicates energyattenuation of the low-frequency band signal caused by encoding of the low-frequencyband signal; and encoding the attenuated high-frequency band signal or the attenuatedto-be-encoded characteristic parameter of the high-frequency band signal. The technicalsolutions according to the embodiments of the present invention can improve the effectof combining the low-frequency band signal and the high-frequency band signal at thedecoder.
