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.

Reducing end-to-end delay for audio communication

Methods, systems, and devices for audio dejittering are described. The method may include determining a mean delay applied to packets in a packet voice communication system, calculating, from the mean delay, a standard deviation for at least a subset of packets in a talk spurt, determining a target delay for the talk spurt by applying a moving average to the standard deviation, and applying the target delay to a first packet from the talk spurt.

Audio dejittering using delay standard deviation

An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value based on previously received audio packets, to identify a receive time of a first audio packet of a talk spurt, to determine an offset value of the first audio packet based on the receive time and the arrival delay value, and to adjust a target delay value associated with a de-jitter buffer based on the offset value. The apparatus also includes a de-jitter buffer configured to buffer the first audio packet based on the adjusted target delay value.
