There are two types of echo cancellation methods: Software (done in our case by the Real Time Optimization Pack Media Engine). Hardware (done by audio 

How Acoustic Echo Cancellation Works Echo can be reduced by adding sound absorbing materials like rugs and carpets, or through more undisguised means like acoustic panels. A more modern way to reduce echo, however, is by investing in equipment technology that does the work for you.

The signal interference caused by acoustic echo is distracting to both users and causes a Echo cancellation is critical to achieving high quality voice transmissions over packet networks, which typically face transmission delays above 30 to 40 ms. These long delays make echo readily apparent to listeners, and must be eliminated in order to provide viable telephony service. Echo cancellation is often needed because speech compression techniques and packet processing delays generate echo. There are 2 types of echo: acoustic echo It is practically impossible for a VoIP system to introduce less delay, so echo cancellation should be used.

Krisp is now officially removing two of the biggest problems during online meetings – room echo and acoustic echo. We’ve all been on calls when voices are echoed during the meeting, or someone’s speech was distorted because their room produced a hollow sounding voice. Our echo canceller can be used both in the client and in the network/cloud cancelling echo coming from the clients and echo coming from far-end networks. The source of the echo is usually acoustic and therefore the echo cancellation technology is frequently named acoustic echo cancellation (AEC). The scope of echo cancellation has also broadened. Begin- ning with the original concept of canceling adverse echo in long-haul voice frequency links, echo cancelers have found wide use in full-duplex data transmission over two-wire cir- cuits [6] [7] and are now being applied to control echo and howl in electronic conferencing applications.

invention of echo cancellers. An important aspect of echo cancellers is that full-duplex communication can be maintained, which allows both speakers to talk at the same time. This objective of this research was to produce an improved echo cancellation

In telephony, the source of these reflections can be generated electrically due to an impedance mismatch in the transmission path or as a result of an acoustic and/or mechanical coupling between a loudspeaker and a microphone, usually because they are in the same physical enclosure.
