What mechanism compensates for jitter in an audio stream by buffering packets and then replaying them outbound in a steady stream?
- WFQ
- voice codec
- digital signal processor
- playout delay buffer
Explanation: Jitter on the network can cause audio problems that can be heard and which are distracting in voice conversations. To compensate for the effects of jitter, a mechanism called a playout delay buffer is used. The playout delay buffer receives and buffers voice packets and then retransmits them in a steady stream with the jitter removed.
