filtergraph, filtertypes have different db scales?

    Sep 08 2013 | 5:18 pm
    Im using the different filtertypes in filtergraph/biquad and finding that they have vastly different db scales, for instance, if I feed "peaknotch" 15db it only reaches about 6db on the scale, but if I feed "lowpass" 15db it reaches around 24db. Im wondering why this is, is there something Im doing wrong, or is there a "correct" scaling to use with filtergraph/biquad?
