Before using a USB microphone with a sound card, it is recommended to say a few words. The current sound mentioned by the subject in the question, I believe that many game veterans often encounter this situation. This is because you may use the headset microphone to play games, but you have not noticed the interference of the computer graphics card. When playing games, the computer’s CPU graphics card is in high-speed operation, which will produce frequency radiation effects, which are just coupled into the computer’s audio circuit, thus causing electromagnetic interference to the sound source audio line of the headset. Therefore, to completely solve the problem of current sound, it is necessary to need a USB microphone with a sound card. So, how to choose a USB microphone with sound card? There are many types of USB microphones currently on the market, with prices ranging from tens of yuan to thousands of yuan. As a practitioner for many years, in my experience, if you want to buy a USB microphone, it is best to choose according to actual needs. If you only use it for game chat, generally the USB microphone with built-in sound card can basically satisfy game communication. If you have requirements for live video recording of live games, then choose a USB microphone with a better sound card.
