Most audio settings have a mic boost and an adjustable mic gain. For Windows 10, this is found by going to Sound -> Recording Devices, and selecting the properties of your microphone.
Step 1: For mics in uni-directional mode (noise cancelling): ensure that the Mic icon on the tip of the boom (just before the pop filter) is facing your mouth.
Step 2: Ensure that Automatic Gain Control (AGC) or similar automated sound levels are turned on.
Step 3: Bend the mic closer to your mouth, but be sure to avoid your breath stream.
Step 4: Adjust the mic gain up until your voice is clear. You can listen to your own mic in the “Listen” tab in the properties of your mic mentioned above. You can also add boost, but note that higher gain and higher boost may also increase “white noise” in the background. We do not recommend more than +10db of boost.
Step 5: Read our tutorial on mic boost using reaper & light host for adjusting mic boost if your PC doesn't have it or if you want to select a number between 0 and 10db.
Step 6: A USB like ours will provide additional power to your mic and enhance the gain and clarity. Certain motherboards may not perform well without a USB or other amp source. This solves the volume problem in nearly all cases.
