How to Increase or Boost Microphone Volume in Windows 8

While using voice-over-IP services such as Skype on your Windows 8 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 boost microphone volume in Windows 8. Sure this applies to earlier versions of Windows 7 and Windows Vista too – but since we are now using Windows 8, we mention Windows 8 specifically.

Boost Microphone Volume in Windows 8

From the Windows 8 Desktop Screen, right-click on the ‘Sound’ icon and from the options displayed, select ‘Recording Devices’.

Again, right-click the active mic and select the ‘Properties’ option.


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 microphon volume may not solve your problem. If it is so, select the ‘Advanced’ tab from the ‘Micrpohone Properties’ window instead of ‘Levels’ and uncheck the option that reads as ‘Allow application to take executive control of this device’.
