Hi, I need some help. I have a USB microphone (novox nc-1 black) and it detects sounds from the surroundings, cars passing outside the window or conversations in the other room, etc. Can the microphone be configured so that it does not detect all this? I do not mean that it will turn on only when the sounds are loud enough, but that those quiet background sounds are not audible when I am talking. Can it be done at all? If so, I would be very grateful for your help.
