Have you ever heard echoes while using video conferencing software (Mail Agent, Skype, QIP, etc.)? The situation is extremely unpleasant and it is necessary to get rid of it somehow. The "echo" effect occurs, as a rule, due to high volume and excessive proximity of the microphone and speakers. Sometimes the echo turns into a nasty squeak, the kind that guitarists make at rock concerts, going up to the speakers. The panacea in this case would be to adjust the mixer parameters of your sound card.
Necessary
Setting up a sound card mixer, microphone, speakers or headset
Instructions
Step 1
In order to remove the echo, it is necessary to determine why such a sound appears. It is also worth determining from which side the echo is coming: from yours or from the side of your interlocutor. To do this, you can ask your opponent to lower the volume of his microphone, as well as turn off the power to all audio devices located near the computer. If the echo persists, then you can safely proceed to eliminate the echo in your audio system.
Step 2
If you are using separate speakers and a microphone, try changing the volume in your speakers, namely lowering it. Do the same with the microphone volume control in the mixer. In order to start the mixer, just double-click the left mouse button on the speaker icon in the tray. First, change the overall system volume. The overall volume should not exceed 70% in the mixer, and turn the microphone volume down until the echo disappears completely.
Step 3
You can also take advantage of the innovations of sound cards - the function "Echo cancellation", in some sound cards this mode is called "Optimal for audio conferencing / IP-telephony".
Step 4
After using all the methods for changing the parameters of audio peripherals, problems with echo should not appear.
