PC users and show business people more than oncefaced with a problem that made them long to rack their brains and look for ways to solve it. What are we talking about? About noise and feedback, which arise when using a microphone. And here it does not matter whether the device is built into your laptop or it's expensive equipment for sound recording. Due to its physical properties, the membrane that captures sound, somehow perceives interference. This becomes an unpleasant moment when talking with IP-telephony, sound recording or just when performing on stage. Today we will try to figure out how to remove noise in the microphone.
First, we will look at methods that avoid the occurrence of noise when using a computer. So, for this, the user needs to have:
Following is an instruction on how to suppress the microphone noise.
There are several reasons whyinterference occurs. The first thing to understand is that different programs on a PC can not physically generate noise. That is, in the vast majority of cases, they arise through the fault of the user. One of the most common causes of noise when using various IP telephony services is the poor quality of the Internet connection. Despite the fact that voice programs usually do not require the presence of a powerful communication channel, you must have at least an average connection speed. Too "weak" Internet is the reason for not only poor sound quality, but also frequent disconnections. How to remove noise in the microphone in this case? The answer is very simple - to increase the connection speed. To do this, during the communication session, you must disable the download of media files and torrents. If the connection speed is initially low, then it makes sense to switch to a faster tariff plan or change the provider.
The next most common cause isproblems with the equipment itself. First, you need to check that the microphone is working properly. If you are dealing with a microphone PC, then you need to run any recording program (a simple utility is included in the Windows OS). To do this, in Windows XP, go to the "Start" - "Programs" - "Standard" and in the "Entertainment" section, find the program "Sound recording". If you have Windows 7 or 8 installed, then it's even easier. Click the "Start" button and enter the word "sound recording" in the search field. Run the program. With its help, a short section of your decision is recorded, after which the sound quality is checked.
If noises are heard on the recording you have made, thenit is necessary to deal with the microphone itself. The correct solution can be the use of another device. But if this is not at hand, you can do with improvised means. Around the microphone it is necessary to make a foam rubber or fur ball (like the TV news reporters). Also, make sure that the microphone is not too far away when talking. If it is placed outside the zone of its sensitivity, the probability of the occurrence of interference increases many times.
The last cause of noise - errors in the softwaresecurity. How to remove noise in the microphone, if the two previous methods did not fit? You must reinstall the sound card drivers. Usually the disc comes with a motherboard (if the card is built-in) or in the box with the sound card itself. For Realtek audio cards, you can enable noise and echo cancellation. To do this, go to the sound control panel on the tab "Microphone", in which opposite the corresponding options to tick.
Another effective solution may bedecrease the sensitivity of the microphone, because it is possible that it simply records much more than it should. To do this, you need to find the "Audio Settings" menu in the Internet telephony application you are using. In the opened window, you should adjust the volume slider (it is possible that you have it in its maximum position).
How to remove noise in a microphone during a performanceor working in a recording studio? Prior to live performance, you must preset the microphone. To do this, on the mixing console should be selected the optimal ratio of the sensitivity and volume controls. Often, noise occurs because the input signal strength slider is too high. That is, it makes sense to reduce the sensitivity of the signal.
If you do not get rid of extraneous sounds,and they are audible on the record, then the program for suppressing microphone noises will help. Its algorithm reliably removes the entire sound spectrum, which has a volume lower than the preset one. Thus, noise will be removed from the sound track, while voice and musical instruments will remain untouched. Now you know how to remove the background noise of the microphone.
