Jitter Buffer
It’s a hardware device or software process that eliminates jitter
caused by transmission delays in an Internet telephony (VoIP)
network. As the jitter buffer receives voice packets, it adds small
amounts of delay to the packets so that all of the packets appear
to have been received without delays. Voice signals are
sequential by nature (i.e., they must be played back in the order
in which they were sent) and the jitter buffer ensures that the
received packets are in the correct order. Without a jitter buffer
to smooth the transmission, data can be lost, resulting in choppy
audio signals.
