An audio decoding method and apparatus are disclosed. The audio decoding method includes: receiving data packets; when data packet loss is detected and audio data of an audio frame corresponding to M channels in N channels is lost, if audio data of other channels than the M channels in the N channels, which belongs to the same audio frame as the lost audio data in the audio frame, is not lost, decoding the un-lost audio data; extracting a signal characteristic parameter of the data obtained after decoding; determining whether a correlation exists between a first channel and a second channel; and if the correlation exists, performing packet loss concealment processing on the lost audio data of the audio frame corresponding to the first channel according to the second channel. The audio decoding method and apparatus can effectively improve the effect of packet loss concealment processing in audio decoding. |
