8. Method of decoding an encoded audio signal, comprising:
receiving the encoded audio signal, the encoded audio signal comprising a first encoded signal, a first processed signal in a second domain, and a second processed signal in a third domain, wherein the first encoded signal, the first processed signal, and the second processed signal are related to different time portions of a decoded audio signal, and wherein a first domain, the second domain and the third domain are different from each other;
decoding the first encoded signal to obtain a first decoded signal;
decoding the first processed signal or the second processed signal,
wherein the decoding the first processed signal or the second processed signal comprises:
inverse processing the first processed signal in the second domain to acquire a first inverse processed signal in the second domain;
inverse processing the second processed signal in the third domain to acquire a second inverse processed signal in the second domain;
combining the first inverse processed signal in the second domain and the second inverse processed signal in the second domain to acquire a combined signal in the second domain; and
converting the combined signal in the second domain to the first domain to obtain a converted signal in the first domain, wherein the converting comprises an LPC synthesizing controlled by LPC information; and
combining the converted signal in the first domain and the first decoded signal to acquire the decoded audio signal in the first domain.
