Advice 1: How to remove the background microphone

Background microphone can considerably ruin your recording or live performance. The microphone is a highly sensitive equipment, the quality of which can be affected by many factors, such as the breaking of contacts in the wires, the proximity of other devices, noises, etc. in order to ensure perfect operation of the microphone, before you begin recording or live performance, you must carefully conduct a thorough review and adjustment of the device.
How to remove the background microphone
You will need
  • Microphone, computer
Instruction
1
Check the cable of your microphone and Jack. Very often noise is created by the damaged cable that has broken contacts. Test the MIC with different cables to find the perfect option.
2
Make sure that there's no other microphones or devices which can create high frequency noise flowing through the speakers. Wind or any air fluctuations can also be a hindrance for normal operation of the microphone. In such cases it is recommended to use a windproof nozzle.
3
If you use microphone for recording on your computer, check volume settings entry in the configuration of your sound card. Adjust the volume to the optimum level.
4
Speak or sing directly into the microphone as close as possible to him. The less you amplify the MIC, the less noise it picks up.
5
If you record a sound on a computer, you will be able to handle your account with special filters to remove noises which are usually included with any audio editor. In addition, during recording, you can use EQ. For example, if you record a low deep voice, and the MIC captured the high-frequency noise, the EQ settings is a bit to remove the upper frequencies and add the bottom.
Note
To work with EQ and filters is carefully, otherwise the sound may become unnatural, flat.
Useful advice
If you record sound at home, you should ensure that the space was isolated from extraneous noise

Advice 2 : How to remove microphone noise

When you work with microphones , the user often has to face various kinds of interference. To eliminate such interference is possible only in case, if known reason for their occurrence.
How to remove microphone noise
Instruction
1
Determine the cause of interference by their nature. A strong hiss when recording outdoors can be caused by exposure to the MIC of the wind. Any kind of crash that occurs when displacement of the microphone that occurs when cliffs and the circuit wires. The presence of the signal, in addition to voices, background noise (the noise of cars, voices of people far from the microphone), indicates an incorrectly selected radiation pattern. Finally, the hum, the frequency of which depends on the distance between the microphone and the speaker - a consequence of acoustic feedback.
2
To protect the microphone from wind, use a special cap which is called windproof. He cannot enter into the delivery set of the device, and if not, just wrap it in several layers of foam with a total thickness of about 10 millimeters.
3
In the presence of cod, try to find, when bending what is the part of the cable it occurs. There is an intermittent short or open. Repair it.
4
To the microphone was sensitive only to the voice of the speaker, but not to background noise, change it on the other, has a narrow radiation pattern. Good results are differential microphones DEM and DEMS not sensitive to sounds, equally affecting the membrane on both sides. In a particularly noisy environment the microphone together to use the throat microphone.
5
To eliminate acoustic feedback, you can also use the differential microphone or the throat microphone. But they are rarely electret, and therefore to work in conjunction with a computer, this solution is unsuitable. Good results in this case can give piezo-electric throat microphone, developing a voltage of sufficient amplitude. It needs to be well electrically isolated from the neck. When you use an ordinary microphone, try lowering the speaker volume or put the device away from them. Finally, a radical solution is to use during recording or performance karaoke speakers instead of headphones.
