1.PCs do not recognize the USB microphones

usb microphone guide

Method 1: Disconnect the USB microphone from the PC and restart the PC

You can disconnect the USB microphone from the PC and restart the PC. After restarting, reconnect the USB microphone to the PC, and if it is not recognized by that particular USB port, try another port. If that microphone is recognized by a different USB port, there may be a hardware problem with one of the USB ports. It is probably something else if none of the USB ports recognize the microphone, so read on.

If the above method does not solve the problem, please turn off the laptop for half an hour (desktop computers can be turned off and unplugged the power cable), wait 15 minutes, and try again.

Method 2: Change the Property of the USB Root Hub

First, open “Device Manager”, expand “Universal Serial Bus Controllers”, and right-click “USB Root Hub”-“Properties”.

3. Noise problem of USB microphones

Is your microphone producing a buzzing, hissing, or humming noise? Self-noise is produced by almost all microphones. It can be very noticeable at times and very subtle at others. The buzzing, hissing, or humming sounds may become more noticeable as you add EQ, compression, and other audio effects.

A.How to Stop Your Microphone From Buzzing?

Your microphone may be making noise for a variety of reasons. Noise can be caused by cable issues, electrical issues, or ambient noise in the room.

1. Check that all cables are properly connected or replace the cables to see if the noise problem persists

If the problem persists, please read the troubleshooting guide below to assist you in determining the source of the problem.

2.Check that your recording environment is quiet
Dynamic microphones are directional and less prone to noise problems, but for condenser microphones, this is a big problem, as these types of microphones are more sensitive and more likely to pick up ambient noise.

There is a way to help you determine if your recording environment is quiet. Sometimes you don’t notice the noise, but you will start to notice the slight buzzing once you start mixing.

You can increase the gain of your microphone and start walking around the recording room with the microphone. Monitor the output using headphones. If you find a noise that interferes with your recording, turn off the equipment that is making the noise. If you can’t turn it off, try to keep the microphone as far away from the noise-causing equipment as possible while recording.

Buzzing from air conditioners, lights, fans, or some electronic devices is common. This will affect your recording.

3. Check the cables

You’ve checked your room for background noise and then turned down the preamp gain. You can replace the cables of the microphone and the audio interface with other cables and see if the noise is still there. This can be a direct solution to your audio problem and can save you a lot of time.

This a common mistake made by beginners. When you buy a new cable for your microphone, you need to check the shielding and connectors of the cable, as this is where the quality of the recording will be most affected. Another thing to keep in mind is that if your cable is damaged, it will affect the audio quality. So check your cables regularly for damage.

4. Check your audio interface and preamp or change another USB port.

With XLR mics, if you use preamps or audio interfaces, some preamps and audio interfaces may produce unhealthy signals that can cause humming or buzzing background noise. Make sure your gain is not set too high, try turning your mic gain down and see if the problem is fixed.

For USB microphones, you can try plugging the USB cable into another port on your PC to check if there is still a noise problem.

5. Check your audio software

Sometimes it can be a digital audio workstation that causes the problem. Make sure that all input controls are not too high. You can also download a free digital audio workstation like Audacity and see if the problem still exists.

6. Faulty Hardware

Nowadays, there are relatively few static hardware problems, but they may still happen. For many reasons, hardware wears out and can suddenly break or degrade. The problem is often electrical. It may have been exposed to static electricity which can cause the hardware to degrade over time, causing hardware problems.

The only way to fix the hardware is to have it repaired or replaced. If your microphone still produces a hissing sound, try recording at a low level with all the input options on your audio interface or preamp. If it doesn’t work, try replacing the microphone and see if that solves the problem.

B.The Solutions for Recordings With Background Noise

1. Noise Suppressor Plug-ins

Some digital audio workstations, such as DAW, have noise suppressor plug-ins in their software. It usually helps to remove the noise made by the microphone.

Logic Pro X has a plug-in called Noise Gate. It improves vocal clarity, removes noise, and prevents sounds from passing below a certain threshold. Signals can only be passed at audio levels above the specified threshold. If the signal is below the threshold, the signal will be blocked. This will effectively block the noise.

Another tool is the X-Noise audio plug-in from Wave. Each digital audio workstation has its own plug-in. It's a good idea to research whether your DAW has any suitable plug-ins.

2. EQ can be used to remove the hissing or buzzing sounds

There is no way to completely remove the noise without destroying the audio as it is recorded in the audio wave, but rest assured you can reduce the buzzing or hissing sounds using EQ. While this may interfere with the recording and reduce the sound quality, it is a method that can be tried.

C.Why is the microphone buzzing?

If the microphone is making a buzzing sound, it could be a loose cable connection or a faulty cable. If you have tried to replace the cable and the problem still exists, it may be a microphone that has been damaged internally. If your microphone is still under warranty, please contact us to see if it can be replaced or repaired. Sometimes it can also be a problem with your digital audio workstation, so be sure to check your software to see if it is the source of this problem.

D.Why is the microphone making the whistling sound?

This whistling sound, also called audio feedback, is due to the endless loop produced when the microphone picks up the sound from the speakers (stage monitors or PA speakers) and sends it back to the speakers for amplification and pickup, causing a specific frequency to be boosted, depending on the resonance of the room and speakers, etc.

The solutions to the whistling sound produced by the microphone:

1. Orient the speaker away from the microphone, or place it further away.

2. Lower the speaker volume or microphone gain.

3. Use a unidirectional cardioid microphone, which has a rear-repelling effect, meaning no sound is picked up from behind. Then you can use a speaker facing you in the middle of the recording room.

4. Deliberately create feedback by placing the microphone close to the speaker. When the audio feedback occurs, check the frequency on the real-time analyzer and use a channel EQ or graphic EQ to cut it.

5.You can also use a feedback reducer to improve this situation.
