Analysis of common problems in the use of multimedia conference rooms

With the increasing use of multimedia conference rooms, the requirements for multimedia conference rooms are getting higher and higher. For multimedia conference rooms, everyone may say that the picture clarity is more important. In fact, in the multimedia conference room, the audio source is also Very important, because the communication between the participants is mainly through audio dialogue or discussion. As long as the video has pictures, it is of course best if it can be clearly expressed, but the most convincing is definitely audio, with good video and ordinary. The audio is much more useful than a normal video with good audio. Of course, since the emphasis on audio products is not very high now, the probability of audio problems is high during video conferencing.

Here are some common audio sound issues when using video conferencing systems:

1, the sound is light during the audio call

This is mainly because the voice passed by the other party is very light, and it takes a lot of effort to understand what the other party is talking about. The problem is generally in the collection of sound. The party can test its own speaker or speaker first, and use the local computer to play the test to see if the volume of the playback is large enough. If it is determined that the audio downlink is normal, you can basically judge the problem. In the uplink, you can generally adjust the volume of the device input (recording). This requires special signature. It is to adjust the recording volume. In practice, many people only adjust the sound of the speaker, but not the size of the recording volume.

2, the noise is relatively loud during the audio call

The size of the noise mainly has two aspects. First, there may be noise sources such as fans and air conditioners during the conference. However, the general conference audio pickup products will not have special noise processing, resulting in noise being picked up. Second, the audio is up, the volume of the recording is too large, resulting in a small motion with a large sound collection, causing noise, of course, sometimes there are some functions in the conference software, such as noise reduction, squelch and other functions When it conflicts with the software, it is easy to cause noise.

3. I can hear my voice during the multimedia conference room.

During the multimedia conference room meeting, I found that I could hear my own voice and sent it back. For example, when many mobile phones use hands-free, it is also very easy to appear. This type of audio equipment is not good choice. Although the current video conferencing software has the function of eliminating echo, none of them can really eliminate the echo, so the rear-end audio equipment is also needed to match, such as the omnidirectional microphone of the Elite audio, which needs its own echo cancellation function. In order to ensure that the other party's voice comes out of the speaker, it will not be transmitted from the pickup part of the product, resulting in echo. If the conditions are limited, the sensitivity of the audio input device can be reduced, the spatial distance of the sound pickup device and the speaker, the power amplifier, the sound reduction and the echo effect can be improved by the distance effect. If you have a better plan, you are welcome to communicate and connect with the company's technical staff.
