Claim:
1. A method for decoding a speech/audio bitstream, comprising: performing decoding operations on a bit stream, wherein a decoded parameter of a first frame and a decoded parameter of a second frame are acquired via the decoding operations, and wherein the second frame is a previous frame adjacent to the first frame; performing, according to the decoded parameter of the second frame, post-processing on the decoded parameter of the first frame to obtain a post-processed decoded parameter of the first frame when at least one of the first frame or the second frame is a redundancy decoding frame; and reconstructing a speech/audio signal using the post-processed decoded parameter of the first frame, wherein the decoded parameter of the first frame comprises a spectral pair parameter of the first frame, wherein the decoded parameter of the second frame comprises a spectral pair parameter of the second frame, and wherein performing post-processed on the decoded parameter of the first frame comprises weighting the spectral pair parameter of the first frame and the spectral pair parameter of the second frame.
