Improperly configured microphone sensitivity settings can lead to unwanted background noise or a buzzing sound when putting your microphone to use. This can often cause annoying or painful situations when attempting to record high-quality audio. 

Experiencing mic sensitivity in Windows 10 is not an uncommon occurrence. Typically, the default settings that the Windows 10 operating system provides are not yet optimized for background noise reduction. Definitely not something you want plaguing your recently uploaded YouTube video or podcast session.

This problem will require that you understand how and why adjusting your microphone sensitivity settings is the only good solution for crystal clear audio. You could opt for a noise cancelling microphone, and you should, but knowing the steps to take for changing mic sensitivity is still essential for the best possible audio setup.

How To Fix Mic Sensitivity In Windows 10

Before we begin, here are a few tips to follow that will increase your chances for crystal clear audio output.

  • So long as you have the budget, never purchase a low-quality microphone. You should always choose a high-quality microphone or headset with a noise cancelling microphone as either will provide a better quality sound.
  • Continuing on with the high-quality over low-quality microphone choice, a mic with a USB connection will usually offer an inferior sound to one using a 3.5mm connection. USB microphones are decent enough for beginners but to further your goal of reaching the “perfect audio” quality, 3.5mm is the better choice.
  • To further minimize background noise, we recommend an Air Filter and Pop Filter for your microphone setup.
  • You should ensure that your mic is no more than a foot away from your face while speaking. The optimal distance varies from person to person. To discover yours, perform a precheck prior to beginning a project.
  • Additional prechecks to make: ensure that the microphone is fully charged (if it runs on battery power), the volume is set to at least half (If it has its own volume control), the microphone connection to your computer is secure, and both the audio and microphone’s drivers are up to date (you can find a short tutorial on this at the end of the article).

You have the tips, so now let us provide you with the necessary steps to help fix mic sensitivity in Windows 10.
