NyquistEq – Free EQ Vst Plugin Effect is part of Magnus’s plugin range available to download at Smartelectronix
You’ll need to scroll down Marcus’s page there to find it.
Parametric graphic equalizer with excellent response all the way up to Nyquist. It never clicks, and it handles deep bass well too. The Nyquist frequency is the highest representable frequency for a given sample rate. The trebliest of the treble. Most other digital eqs have great problems producing a natural sound here.
