 28th August 2018, 09:12 AM #22 David McBean   diyAudio Member   Join Date: Jun 2007 The following explanatory note will be added to the Filter Wizard section of the Hornresp Help file in the next update. ================== In some parametric equaliser software packages the shelving filter 'Q Factor' is actually S, a "shelf slope" parameter. The relationship between Q and S is given by the expression: S = 1 / (((1 / Q) ^ 2 - 2) / (10 ^ (G / 40) + 1 / (10 ^ (G / 40))) + 1) Where: S = shelf slope parameter Q = Q factor G = gain ================== __________________ www.hornresp.net
