Manual Audio Believer
 

Did some tests tonight with a RODE SVM on a boom and a rather long extension cord. The test was with Auto turned on, second was with all the sound right around -12 dB on ave but with some 0 peaks. The last was keeping everything down below 0 for sure and for the most part below -12. It sounded great!!
Did use NewBlue Cleaner on the remove noise preset but it was crystal clear audio.

Suppose like high ISO and Custom white balance it's best to set back on auto for everyday.

But definitely see the value in manual now.
