Echo Cancelor

Echo Canceller is designed to cancel acoustic feedback

between a loudspeaker and a microphone in loud speaking

audio systems.

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.
