my comment: The technicalities of this are way beyond me, but I would
be suspicious of any recorder function that claims to reduce noise.
If you need to remove noise, do that later using computer software.
Just my 2 cents worth :-)
Pleased to hear you are using my SASS variant.
And good luck with those ultrasonic insects!
