The microphones in the system at the far end also need echo cancellation.Д¬IE is a multi-award winning distributor of professional audio equipment. This means only the sound of the person speaking into the microphone is mixed with the other microphones and sent to the far end. The echo cancellation circuitry examines the sound going into the microphone and compares it with the sound coming from the far end it then cancels out the sound detected in both signals as that can only be the sound from the far end. It can be more complicated in the AV world because conference rooms may have several of microphones set up in them.Д®ach microphone needs a separate echo cancellation into the signal processor this is because each microphone will be in a different location and will pick up a slightly different sound. This happens because of the small time delay that the video conferencing links have, this means that you will get an echo of the sound that will repeatedly bouncing back and forth.ДЄudio Echo Cancellation was invented to prevent this problem from happening, providing a better quality of sound.ДЄudio Echo Cancellation is commonly used on everyday devices such as smart phones (especially when used in loudspeaker mode) and on video calling systems (e.g. This sound then gets returned back to the far end and comes out of their loudspeakers in the room and also goes into their other microphonesand then back again. When the audio from the far end comes out of the loudspeakers people in the room will hear it through their ears as they should, however, that sound also gets picked up by other microphones in the room. The audio travels through a room the journey it takes explains why Audio Echo Cancellation is needed. However, this would produce very poor quality of sound without the use of Audio Echo Cancellation. A mix of the microphones in the room will also be sent to the far end. In a standard conference room, audio will come from the far end and will be played out of the loudspeakers. In general, there will be a video conference codec this will have one audio input and one audio output. One of the common things in conference audio system is a connection for video conferencing.
