摘要
A technique is described for updating a state of a decoder. In accordance with the technique, a decoder state is aligned with a synthesized output audio signal at a frame boundary. An extrapolated signal is generated from the synthesized output audio signal. A time lag is calculated between the extrapolated signal and a decoded audio signal associated with a first received frame after the lost frame in the series of frames, wherein the time lag represents a phase difference between the extrapolated signal and the decoded audio signal. The decoder state is then reset based on the time lag.
