 NOTE: Using Soft Target (as opposed to Soft Response Gain) allows using a stable reference for calculating the VC Range before running an Autofit.  Using the Soft Response Gain requires performing an Autofit first (to obtain the response curves), and then calculating the VC Range based on those curves.  The problem that emerges from the latter is when the VC Range modifies the response curves. In Intricon products, the response curve is kept in the middle of the VC Range. So for a 20 dB range, the response curve has +10 dB and - 10 dB. For a 50 dB range, it gets modified to have +25 dB and -25 dB, but the response curve is changed as well, no longer matching the autofitted response curve. NOTE: Using Soft Target (as opposed to Soft Response Gain) allows using a stable reference for calculating the VC Range before running an Autofit.  Using the Soft Response Gain requires performing an Autofit first (to obtain the response curves), and then calculating the VC Range based on those curves.  The problem that emerges from the latter is when the VC Range modifies the response curves.
