SplineEQ is a linear phase equalizer plugin (VST/AU). Designed to be simple and flexible, SplineEQ allows you to create filters using Bézier splines, the best known way to design curves. The free trial of SplineEQ is for personal use only, but if you purchase SplineEQ it comes with a full commercial license.


  • Linear phase equalizer
  • Spline-based filter design
  • Up to 60 bands (only up to 4 in the free version)
  • Simple curve modification functions
  • Frequency analyser
  • Infinite dB to +60 dB gain range
  • Adjustable resolution, latency more...

What's New

Version 1.0.9:
  • The Limiter doesn't distort the sound anymore but always caps it to the threshold (so it will never be too loud no matter what you do), which now can go down to -30 dB, while preserving the dynamics and the quality of the sound./li>


  • Mac OS X 10.4 or later
  • A VST/AudioUnits compatible host.

Really great for both subtle and drastic eq duties. Can be really transparent if you use it with care.

The fact that you can draw your own eq curves makes it as versatile as you want it to be.

Instantly seeing how you modify the spectrum with the color feedback is amazing and it has to be seen to be believed.

Get the demo now as it is fully functional but only allows for 4 bands (which for most of the tasks is enough).

I recommend this eq wholeheartedly for basic clean up duties as well as extreme soundshaping and sometimes mastering duties.
