Several factors influencing the sound quality of video conferencing
Video conference omni-directional microphone is in recent years, along with the video conference is derived by gradually recognition after an audio product, it integrates the microphone and speaker and an organic whole, and echo cancellation, noise filtering, all-around practical functions such as pickup, so get the consensus of users. But there are also a number of users who reflect the poor quality of the sound quality, the echo and the noise, so we will analyze the factors that cause these problems.
First, what is the performance of the video meeting to the microphone itself.
The video meeting is all about the echo cancellation function that the microphone itself should have, how to recover the sound quality, whether there is a noise, and how to pick up the sound. These factors directly determine the quality of the microphone in the remote video meeting. How do we listen to the sound quality through the recording?
This gives you an intuitive sense of how the sound is, and we can also record the music and then detect the echo of the video meeting all the way to the microphone. It is possible to determine whether the video meeting is superior to the microphone.
Second, the operating system used for the two processing of sound quality.
We usually see two kinds of computer operating systems, XP, WIN7. These two systems have different processing of audio, so let's start with the XP system.
What should we do with XP? Mouse over the bottom right corner of the computer table, and click the volume icon right - voice - voice output - advanced - audio acceleration and sampling to the left side. The aim is to ban the second amplification of the audio from the XP system, ensuring that the original video meeting gives maximum performance to the microphone.

There's not much we can do under Windows 7, but we can adjust it by lowering the sound volume of the microphone and the volume of the speaker.
Third, the video conference software for the second processing of sound.
Usually video conference will take place on the audio codec, with high quality, low quality, will also have to eliminate echo, eliminate noise and similar options, then we choose according to network status, remove to eliminate echo, eliminate noise, purpose is the same video conferencing software for audio processing, play a video meeting the maximum performance of omni-directional microphone.
