The PSP MasterQ plugin was designed to be a high quality parametric equalizer that will operate sampling rates ranging from 44.1 to 192kHz .

The plug-in contains seven filters: 12 or 24 dB/oct low cut and high cut filters, low shelf and high shelf filters, and low mid, middle and high mid peaking filters-all of them with adjustable frequency and Q factor over a wide range.

The plug-in also includes a high precision EQ graph to display an overview of the EQ curve, as well as display the individual characteristics of each filter.
