Voxengo has announced the 3.3 version of their Linear-phase spline equalizer.
CurveEQ is a spline equalizer for professional music and audio production applications. CurveEQ shows you the actual filter response you are designing by means of a spline (a smooth curvy line), so you can actually see what the EQ is doing with the sound. This, in turn, allows you to get the best from your mix and your tracks. CurveEQ perfectly suits the needs of mastering.
Changes included in the new 3.3 version are:
CPU load decreased by 20%.
Implemented a fast Shift+Click insertion of control points.
Implemented a more flexible way to copy envelopes.
Fixed the “Underlay” selection issues.
Added VST3 support.
