add one more point that is later not used to fit the spline so that the transition between the two frequency regions is smoother

fit the spline only for the high frequencies, for low frequencies keep the A2B coefficients untouched, make graphs of filters better

add maximum amount of boost to limit filter ends after fitting the spline, this still does not work out in low frequencies, perhaps we need to fit the spline only in the upper frequency range and just leave the A2B matrix alone in the low frequency range

change the way the filter is designed, get a spline to interpolate a smooth frequency response curve, plot some graphics to see what is going on
