Hi Marc, As I understand it, this represents the peak amplitude you want the AGC to aim for. If you look at preprocess.c, you'll see that this should be a float from 1 to 32768, with the default being 8000. I've been using 70% of the maximum in my application. You should probably experiment to see what works best for you. Tom Marc <maarcc@gmail.com> wrote:> > Hi. > I am trying out 1.1.9.
