Thanks for the useful comments.
Is there any suggestions on the calibration strategy and how to monitor
for clipping. Right now, I am going to re-adjust the gain on bins that
are below 1000 auto-corr units and try to make the spectrum as flat as I
can ( by looking at the spectrum every second). Once this is settled (or
maybe it won't), I will re-adjust gains only once every so-many minutes
maybe. Does this sound reasonable?
