Patent ID: 8214206

Claim:
A method for reducing audible artifacts in an audio output signal generated by decoding a received frame in a series of frames representing an encoded audio signal in a predictive coding system, comprising: determining if the received frame is one of a predefined number of received frames that follow a lost frame in the series of the frames; altering from a state associated with normal decoding at least one parameter or signal associated with the decoding of the received frame responsive to determining that the received frame is one of the predefined number of received frames, wherein the at least one parameter or signal relates to a scale factor associated with an adaptive quantizer, a stability margin for a low-band pole section of an adaptive predictor, a partial reconstructed signal, or a reconstructed signal; decoding the received frame in accordance with the at least one parameter or signal to generate a decoded audio signal; and generating the audio output signal based on the decoded audio signal.
