Echo Cancellation - Retaining Echo Suppressors

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:

    ... whilst you are proclaiming peace and good will to men, Emancipating all Nations, you insist upon retaining absolute power over wives. But you must remember that Arbitrary power is like most other things which are very hard, very liable to be broken—and notwithstanding all your wise Laws and Maxims we have it in our power not only to free ourselves but to subdue our Masters, and without violence throw both your natural and legal authority at our feet ...
    Abigail Adams (1744–1818)

    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)
