Retaining Echo Suppressors
Echo suppression may have the side-effect of removing valid signals from the transmission. This can cause audible signal loss that is called "clipping" in telephony, but the effect is more like a "squelch" than amplitude clipping. In an ideal situation then, echo cancellation alone will be used. However this is insufficient in many applications, notably software phones on networks with long delay and meager throughput. Here, echo cancellation and suppression can work in conjunction to achieve acceptable performance.

Famous quotes containing the words retaining and/or echo:
“Housework is a breeze. Cooking is a pleasant diversion. Putting up a retaining wall is a lark. But teaching is like climbing a mountain.”
—Fawn M. Brodie (1915–1981)
“To write is to make oneself the echo of what cannot cease speaking—and since it cannot, in order to become its echo I have, in a way, to silence it. I bring to this incessant speech the decisiveness, the authority of my own silence.”
—Maurice Blanchot (b. 1907)
