ouch,
"I think the point that was being made (not by me) was that regardless
of mic sensitivity, the recorded noise can never be better than the mic
noise floor, so that is the only number that really matters when
comparing the "potential" lowest total recorded noise."
I will have a good nights sleep and try tomorrow and see if I can
understand all implications in that sentence!
Haha, smiley smiley and good night from here!
