An audio data recovery method, an audio data recovery device and a Bluetooth device are described. The audio data recovery method comprises: dividing audio data into a first frequency domain component and a second frequency domain component in a frequency domain; using a second data recovery algorithm to recover the audio data in the second frequency domain component; and using a first data recovery algorithm with lower complexity than the second data recovery algorithm to recover the audio data in the first frequency domain component.

Audio data recovery method, device and bluetooth device

An audio packet loss concealment method, an audio packet loss concealment device and a Bluetooth receiver are described. The audio packet loss concealment method comprises: determining whether each data packet divided into a plurality of frequency bins in a frequency domain is correct after audio data is transformed from a time domain to the frequency domain; classifying the frequency bins in the incorrect data packet into a first set of frequency bins and a second set of frequency bins; and recovering data in the first set of frequency bins by a GAPES algorithm, and recovering data in the second set of frequency bins by a predefined algorithm, wherein the predefined algorithm involves far less computation when compared with the GAPES algorithm.
