I have an USB microphone that has a gain control knob. As I understand, the gain here means the voltage amplifier gain inside the microphone. USB microphone will have an maximum output voltage of 5V, so if the gain here is too high, sound might be clipped.
In Windows 7, when you go to microphone properties, you can adjust the mic "level" from 0 to 100, and also mic "boost" in decibels. Can you help me make sense of those two concepts and how they work?
I have an noise evaluation application where the amplitude of the signal is highly important so it'll be good to understand and control these parameters properly.
