Patent ID: 8078458

Claim:
A method for generating a full-band audio signal based on a series of encoded frames in a sub-band predictive decoder, comprising: decoding one or more received frames in the series of encoded frames to generate a portion of the full-band audio signal corresponding to the one or more received frames, wherein decoding the one or more received frames comprises generating a first sub-band decoded audio signal, generating a second sub-band decoded audio signal, and combining at least the first sub-band decoded audio signal and the second sub-band decoded audio signal; storing the first sub-band decoded audio signal and the second sub-band decoded audio signal; and responsive to determining that a frame in the series of encoded frames is lost, generating a first sub-band replacement audio signal based on the stored first sub-band decoded audio signal; generating a second sub-band replacement audio signal based on the stored second sub-band decoded audio signal; and combining the first sub-band replacement audio signal and the second sub-band replacement audio signal to generate a portion of the full-band audio signal corresponding to the lost frame.
