While using voice-over-IP services such as Skype on your Windows 10/8/7 desktop, you may have observed sometimes the quality of voice sinks. Under such circumstances, you may have to boost the volume to recover the audio quality. So if you think your Microphone volume is too low at times, this tip will tell you how to increase or boost microphone volume in Windows. This post will also help you if the Microphone Boost option is not available.

From the Windows Desktop Screen, right-click on the ‘Sound’ icon and from the options displayed select ‘Recording Devices’.

Then, under the Microphone Properties window, from the ‘General’ tab, switch to ‘Levels’ tab and adjust the boost level.


By default, the level is set at 0.0 dB. You can adjust it up to +40 dB using the slider provided.

Be sure to carry out the process during your conversation so that you get the feedback from the other end immediately. This will also tell you whether the adjustments made are appropriate or not.

Microphone volume too low

In rare cases, it has been observed that boosting the¬†microphone volume may not solve your problem. If it is so, select the ‘Advanced’ tab from the ‘Microphone Properties’ window instead of ‘Levels’ and uncheck the option that reads as ‘Allow application to take executive control of this device’.

Microphone Boost option not available

Audio features depend on the chipset and drivers installed. If you do not see the Boost option, you may try the following:

  1. Change the port to connect the Microphone
  2. Run the Recording Audio troubleshooter
  3. Update Drivers: Updating Sound, Microphone & Audio drivers will help. If it is a Realtek chipset, you can get the updated drivers from Realtek.

Hope this helps!
