Why is there an electric current sound in the recording, and how to eliminate the current sound in t

The recording has the reason for the sound of the current:

1.Motherboard current serial, electromagnetic interference.

Cause. (This is mainly due to the poor workmanship of the motherboard of the computer, resulting in the instability of the power supply of the electrical components and the electromagnetic interference between the electronic components.) This situation mainly occurs on some old computers, if you want to record a clearer sound, it is only recommended to record on a different computer. ）

2.The microphone interface is virtually connected to the computer microphone interface. (You can reinsert the microphone into the microphone interface, desktops generally have two sets of interfaces, if the front one doesn't work, you can plug it into the back one.) ）

3.The audio driver is incorrect.

Recording is the process of recording a sound signal on a medium. The process of reproducing sound from a signal recorded on a medium is called playback. The two processes of recording and playback are collectively referred to as recording and playback.

The common ones are record recording, tape recording and optical recording. As far as the recording and playback formats are concerned, there are mono and stereo sounds.

Recording and playback. The mono recording and playback process includes a microphone.

Pickup, amplification, recording, and replay by a single amplifier and speaker system. Binaural stereo recording and playback is based on the human binaural localization effect and the dual-source listening effect, and the binaural system completes the process of recording and replaying sound.

There is no problem under normal conditions

However, if you use a recording, there will always be an electric current sound.

I still have the microphone and the speaker unplugged respectively

Then it shouldn't be a problem with the microphone and the speaker, right?

What exactly is the question of **?

Is there an indication of electromagnetic signal interference around your computer?

Like ordering a refrigerator.

Microwave ovens and the like.

Summary. Hello dear, I am glad to answer for you: the recording current sound cancellation method is as follows; Go to a quiet environment to record, put the mobile phone a little farther away when recording, use headphones to record when recording, and put a wet paper towel on the microphone; Close the recording software and try to reopen it, if none of the above methods can solve the problem, open the phone [Settings], find [Factory Reset], and reset the phone.

Dear Liangzhou, I am glad to answer for you: the recording current sound cancellation method is as follows; Go to the sleepy cherry blossom to record in a quiet environment, put the mobile phone a little farther away when recording, use headphones to record when recording, and put a wet paper rubber ruler on the microphone; Close the recording software and try to reopen it, if none of the above methods can solve the problem, open the phone [Settings], find [Factory Reset], and reset the phone.

What is the cause of the sound of current when recording in a loudspeaker?

1. There is poor contact at the plug of the audio input; 2. The internal resistance of the power supply has increased; 3. It is external electromagnetic interference. The teaching megaphone is a loudspeaker that is mainly used for teachers to teach. At present, it is divided into two categories, one is waist-hung and shoulder-mounted teaching amplifiers, and the other is wireless teaching amplifiers.

Here's how to use it correctly: 1When using the amplifier, the microphone should be avoided facing the speaker, and the volume adjustment should be appropriate and clear, so as to avoid distortion and feedback howling.

2.Do not pull or drag the microphone cable during use, otherwise it is easy to have poor contact between the wires. 3.

The host battery should not be overcharged for a long time, and it should be charged in time when the low power prompts. 4.When idle during winter and summer vacations, you should pay attention to charging once every one to two months.

5.If you don't use it for a long time, you should let the battery discharge be hidden. 6.

If you don't need to do it for a long time, it should be placed in a ventilated, dry place, away from heat sources and magnetic fields.

Support computer recording, audio editing, noise cancellation function. Eliminate the sound of computer current, the sound is clear and free of impurities.

Noise cancellation is checked to remove noise perfectly.

There is a volume icon in the lower right corner of the computer, press the right button to open the recording device, there is a microphone under the recording menu (the computer is displayed only when the headset is plugged in), click on the properties below, the microphone properties will pop up, and under the enhancement menu, there are: DC offset cancellation, noise suppression, echo cancellation. To reduce noise, check :

Noise suppression. If you have Adobe Audition installed on your computer, you can also reduce noise.

1.Check the computer first, click on the bottom right corner of the taskbar, find the sound icon, find the recording device, then find the microphone option, find the enhancement option in the properties, check the noise suppression and echo cancellation, and then turn the microphone enhancement option progress bar down. 2.

Check the quality of the microphone: a better microphone must bring a smaller current sound, if it is worse, in fact, if it is really bad enough to bear, even the later can not be solved, the first time Haas to check whether the microphone is damaged. 3.

There is no problem with the device and the computer, you can turn on the AU to eliminate noise and current: if it is not the problem of the device itself, then use the later method to solve it, because the equipment is always connected to the computer, and the current sound of the computer will be there as long as it is energized, which cannot be avoided and can only be eliminated in the later stage. 2. Tips for solving current sound and noiseIf you want to consciously isolate current sound and noise before recording, then remember the following tips.

1.Close the doors and windows, or buy soundproof stickers on the doors and windows to manually block out the noise. 2.

The microphone should be far away from the computer, away from the current sound of the main unit. 3.If you don't have a budget, use wet paper towels to pad the microphone, and if you have a budget, buy a microphone case or a microphone to reduce problems such as closed microphones.

Having said that, that's all for "how to deal with current sound in recording equipment" and "tips for solving current sound and noise", so if you remember it, try it next time you record.

Summary. 1. Caused by poor quality of mobile phone microphone or poor environment. You can try to use a good external microphone, which can be plugged into the headphone jack for use.

This will avoid the poor quality and poor pickup environment of the mobile phone, and the MIC is outside the mobile phone, and there will be no sizzling current sound. 2. The motherboard of the mobile phone is damaged. It is recommended to send it to a repair center for inspection to avoid further damage.

3. There are other high-power electrical appliances nearby, which causes the mobile phone to produce current sound.
