#define FE2_HIGHPASS_Q

Filter parameter for shape constant ("Q" coefficient).

The Q coefficient controls the "shape" of the filter. In general, higher numbers mean a sharper response
curve. The default value is 0.707, and should be appropriate in most cases. If you feel the default value is
inadequate, iterative experimentation is the best way to select a new value. Alternatively, a mathematical
description of this filter is linked in the references above.
