I am trying to create a correction filter for Equalizer APO for use with my HP Reverb G2 headset. The challenge is that I am sitting next to my CPU (loud fans) and I have a desktop fan blowing at me to keep the headset from steaming up. For a mic I have the Zoom F1 with the LMF-2 which can plug into the PC USB port. I have adjusted the F1 to -12 db. Using a simple sound meter app on my phone, I have measured the ambient sound of the room at -38db. I have been watching videos on how to do a measurement, but I am not sure I have set things up correctly to deal with the fan sound coming from my right side. Can you provide some advice on the best approach?
