Claim 8:
9. A device for concealing audio packet loss, comprising:
a determining module configured for transforming the audio data in a time domain to a frequency domain, wherein spectrum of the audio data is divided into a plurality of bands, the determining module further configured for determining incorrect data packets among n consecutive data packets and average energy in each of the frequency bands, wherein the frequency bands are classified as a plurality of first bins and second bins based on the determined average energy in each of the frequency bands;
a classification module configured for classifying the frequency bands into first bins and second bins; and
a recovery module configured for recovering data in the first bins by a first predefined algorithm, and recovering data in the second bins by a second predefined algorithm, wherein the second predefined algorithm involves far less computation than the first predefined algorithm.
