+    #EXPLANATION OF LDFC CONFIG PARAMETERS
+    # The ColourFilter parameter determines how much the low index values are emphasized or de-emphasized.
+    # The purpose is to make low intensity features stand out (emphasis) or become even less obvious (de-emphasis).
+    # This parameter applies a function that lies between y=x^-2 and y=x^2, i.e. between the square-root and the square.
+    # For an acoustic index value of X, newX = [(1/c - 1) * X^2 + X] * c, where c = the supplied filterCoeff.
+    #    When filterCoeff = 1.0, small values are maximally emphasized, i.e. y=sqrt(x).
+    #    When filterCoeff = 0.0, the matrix remains unchanged, that is, y=x.
+    #    When filterCoeff =-1.0, small values are maximally de-emphasized, i.e. y=x^2.
+    #    Generally usage suggests that a value of -0.25 is suitable. i.e. a slight de-emphasis.
