Abstract:
In an audio signal decoding method, a decoded frequency domain signal of a current frame of the audio signal is obtained by decoding a received bitstream; a predicted frequency domain signal of the current frame is obtained according to the decoded frequency domain signal the current frame when the decoded frequency domain signal meets anyone of two given conditions; and a time domain signal of the current frame is obtained according to the decoded frequency domain signal and the predicted frequency domain signal.

Claim (Index 6):
The method according to  claim 1 , wherein obtaining the predicted frequency domain signal of the current frame according to the decoded frequency domain signal the current frame comprises:\n estimating a position of a formant of a frequency domain signal derived from the predicted frequency domain signal according to line spectral frequency (LSF) parameters; and decreasing an amplitude of a predicted frequency domain coefficient when the amplitude of the predicted frequency domain coefficient near the formant is greater than a threshold.
