Abstract

An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value, to determine a receive time of a first audio packet of a talk spurt, to determine a target delay value associated with a de-jitter buffer based on the arrival delay value and the receive time of the first audio packet. The apparatus also includes a decoder timing control circuitry configured, in response to detecting the first audio being dequeued from the de-jitter buffer, to cause a decoder to start decoding of the first audio packet.
