June 18, 2023: Voxengo CurveEQ update version 3.14 is now available for download.  Voxengo CurveEQ, available in AudioUnit, AAX, VST, and VST3 plug-in formats, for macOS and Windows computers, is a spline equalizer plugin for professional music and audio production applications.

Version 3.14 update includes the following changes:

  • Changed CSV file saving to use a more widely-used semi-colon.  Compatibility with comma-delimiters retained.
  • Fixed a very rare crash when changing the EQ curve if CPU is already overloaded.
  • Fixed a GUI issue that could affect host's transport on Intel Macs.
  • Fixed occasional GUI flickering on macOS (due to usage of Device RGB color-space, now it is sRGB).
  • Improved audio-UI interoperability, to reduce a chance of audio stutter happening when UI is active.
  • Reduced GUI refresh jitter.

CurveEQ shows you the actual filter response you are designing by means of a spline (a smooth curvy line), plus it displays the output spectrum, so you can readily 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.

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 it easily lessens any dramatic differences in the area of frequency balance between various tracks.
