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 8):
An audio signal decoder, comprising:\n a non-transitory computer readable storage medium storing computer executable instructions; and a processor coupled to the storage medium and configured to execute the computer executable instructions to:\n obtain a decoded frequency domain signal of a current frame of an audio signal by decoding a received bitstream, wherein the decoded frequency domain signal is a low frequency part of the frequency domain signal of the current frame, and wherein the frequency domain signal comprises a plurality of subbands and each subband is represented by an index; \n determine whether the decoded frequency domain signal meets at least one of two given conditions; \n obtain a predicted frequency domain signal of the current frame according to the decoded frequency domain signal the current frame when the decoded frequency domain signal meets at least one of the two given conditions; and \n obtain a time domain signal of the current frame according to the decoded frequency domain signal and the predicted frequency domain signal.
