I Tried an Analog Mic But it didn't work at all. This one worked right off and is very sensitive.

Used these to make a sound reactive wled module. Man if it's quiet in the room it will register me tapping my fingers on the desk lightly in my office down the hall. One thing I will say, it's a tight space so soldering it isn't for the faint of heart. And I probably wouldn't have tried it had I known about ledfx first....
