Patent ID: 7852882

Claim:
A method for generating an output audio signal in a communication system, comprising: (a) identifying a segment of an audio signal stored in a jitter buffer, wherein the identified segment is one of a series of segments of an audio signal received over a communication link and stored in the jitter buffer; (b) obtaining an estimate of the power of the identified segment; (c) comparing the estimated power of the identified segment to a power threshold that varies in a manner that depends on a current number of segments stored in the jitter buffer, wherein the power threshold increases as the current number of segments stored in the jitter buffer decreases; and (d) providing the identified segment for the generation of an output audio signal if the estimated power of the identified segment exceeds the power threshold and providing an inserted segment instead of the identified segment for the generation of the output audio signal if the estimated power of the identified segment does not exceed the power threshold.
