<p>Disclosed are an audio decoding method and device. The audio decoding method includes: receiving a data packet; when it is detected that there is data packet loss and there is loss of the audio data of M audio channels in N audio channels corresponding to a certain audio frame, if the audio data of the other audio channels apart from the M audio channels in the N audio channels, and belonging to the same audio frame as the lost audio data in the audio frame, is not lost, then decoding the audio data not lost; extracting a signal characteristic parameter obtained after decoding; judging whether or not there is a correlation between a first audio channel and a second audio channel; and, if so, according to the second channel, then performing packet loss hiding processing on the lost audio data of the audio frame corresponding to the first channel. Also provided is an audio decoding device. The embodiments in the present invention can effectively improve the packet loss hiding processing effects during audio decoding.</p> |
