As the usage of video conferencing continues to increase, everyone has higher and higher requirements on video conferencing. For video conferencing, everyone will say that video is important. In fact, this is not the case, audio is the most important thing. The communication between participants is mainly achieved through audio conversations or discussions. As long as there is an image in a video, it is of course the best if it can be clearly displayed, however, the most convincing thing is the audio. A good video is more useful than a normal audio.

Of course, the importance of audio products is not very high, which leads to a high probability of audio problems during video conferencing.

I. Light voice during audio calls

This is mainly because the voice sent from the other party is very light. It is very difficult to hear what the other party is talking about. Generally, the problem lies in the sound collection. This party can first test its own speakers or speakers and use a local computer to test the playback volume, if it is determined that the local audio downstream is normal, it can be basically determined that the problem is uplink. Generally, the device input (recording) volume can be adjusted. This requires a special signature to adjust the recording volume, in practice, many people only adjust the speaker's voice, instead of the audio volume.

Ii. high noise during audio calls

There are two main influences on the noise. One is that noise sources such as fans and air conditioners may exist during the Conference, generally, conference audio pickup products do not have special noise processing, resulting in noise being picked up. Second, the audio goes up and the recording volume is too high, this results in a large volume of sound collection and noise. Of course, sometimes the conferencing software has some functions, such as noise reduction and static noise, it is also prone to noise.

3. You can hear your voice during a video conference.

During the video conference, I found that I could hear my voice again. For example, many mobile phones are prone to this situation when they are hands-free. This kind of problem is mainly caused by poor selection of audio devices.

Although all the video conferencing software now has the echo cancellation function, none of them can actually eliminate the echo. Therefore, we still need to match the back-end audio devices, such as the ailite audio omnidirectional microphone, the echo cancellation function must be provided to ensure that the voice of the other party is sent out of the speaker and not from the pickup part of the product, resulting in Echo. Due to the limited conditions, the sensitivity of the audio input device can be reduced, the space distance between the sound pickup device and the Speaker and the power amplifier can be increased, and the sound and ECHO can be improved through the distance effect.

4. Magnetic or magnetic sounds are found during video conferencing, and sometimes harsh sounds are not stopped.

This problem is called. From the actual application process, there are two situations that will cause this situation. One is that the local speaker releases the sound of the recording, causing a local scream, this problem can be solved by disconnecting the video meeting, and then directly speaking to the audio pickup product to see if the sound will come out of the local speaker. If it comes out, you need to set it, which is generally in the sound play option, remove the audio output hook of the pickup device to ensure that the speaker is not associated with local sound amplification.

Second, because of the echo on both sides, resulting in a scream, this problem mainly needs to be achieved through the elimination of the echo.

5. Audio calls may sound discontinuous, or sound may sound like a pause.

If the above problem occurs, first check the network cause and whether there is network latency. Check the video options of the intercom to ensure that there is no network cause. If the problem persists after the network problem is rectified, you need to disconnect the software, because sometimes the software may conflict. For example, during QQ's multi-party calls, the main initiator and any party will have a good effect, however, it is easy for other parties who are not the primary initiator to have intermittent and incoherent voices. It is estimated that they are related to the functions of the software. 6. No sound output in a video conference

When encountering such problems, first check whether the local environment is normal. Generally, the problem is analyzed by several steps such as Speaker, software, and computer recording. If there is no problem locally, it is generally that the remote end is not transmitted, in this way, the remote end must first eliminate the problem and determine whether the sound is going up (recording.

If there is no problem, check the video software to see if the audio input device has been set as the pickup device you need. If not, select. Of course, in some conference software, it is necessary for the speaker to speak, and the corresponding functions need to be turned on before testing.

7. Sound changes are very serious and you cannot hear clearly

The above problems are generally caused by software conflicts, or you need to add hardware products after opening the video software, because the computer is prone to software conflicts when dealing with such problems, as a result, it is impossible to work normally. Therefore, you must first eliminate the software-side problems and confirm that there is no problem. Then, let's see if the problem exists.

8. Sound latency

When the sound delay is severe, first test whether the network is in good state. If the network is in good state, search the LAN once, check whether someone is using the network to watch videos or other software operations with high traffic. If so, pause and check whether the sound is continuous. If the network condition is not stable, we recommend that you reduce the video bit stream and increase the audio bit stream. Because the audio output generally does not require a large bit of code stream and requires a low network speed, you can reduce the video bit stream slightly. Although the quality is limited, but the effect can be improved.

These are audio problems that may occur during video conferencing. To address these problems, the developed video conferencing omnidirectional microphone can solve external problems, such as Echo, we don't need to wait until we call the video. As for some other small problems, we can exchange technical information at any time. Our goal is to enable our customers to use video conferences, it is equivalent to chatting on a table at the same time of all attendees, with unique results.
