Voxengo has announced the release of version 3.0 of CurveEQ, a spline equalizer plug-in for professional music and audio production applications, available in AudioUnit and VST plug-in formats (including native 64-bit support), for Mac OS X (v10.5 and later), and Windows computers.

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, and in some cases CurveEQ is suitable for use as an in-track equalizer.

CurveEQ implements spectrum matching technology that allows you to transfer spectrum's shape of one recording to another. In other words, this allows you to “copy” frequency balance of existing time-proven mixes so that other mixes that are still in the works may have a chance to sound better. This technology also greatly helps in music mastering since using it allows you to easily lessen any dramatic differences in the area of frequency balance between various tracks.

CurveEQ's filters can be switched between linear- and minimum-phase modes. CurveEQ also features a deeply-customizable spectrum analyzer like the one found in Voxengo GlissEQ and SPAN plug-ins. You may also display, save and load static spectrum plots for comparison and matching purposes.
