In this free video tutorial brought to you in with the support of Plugin Alliance, Pro Tools Expert team member Julian Rodgers attempts to use bx_refinement to control harshness on a solo violin recording.

Damping Frequencies In The 3.5kHz Region

At its core bx_refinement is a cut-only bell filter centred on the upper midrange. The damping control dials in a fixed cut around 3.5kHz with a choice of two Q settings with hard being sharper than soft. The perceived loss of high end can be countered using the presence control which is a cut/boost high shelf and  additional harmonic content can be introduced using the saturation control.

Dynamic EQ

This upper mid band filter can be modulated by the Dynamics section, which is a band of dynamic EQ which can be tuned by soloing the output of the filter.
