Product Reviews by KVR Members

First off, it is pretty awesome. The gui is slick, styled well, and original. Also, the concept of Spline EQ is fairly amazing. I have always had a blast playing with Vector Graphic programs like Illustrator and Inkscape where you can drag nodes easily and fluidly, and to be able to control eq levels that is way is seriously fun - it opens up possibilities that - while the techniques to produce the sound in question were never not there - suddenly reveal themselves with astonishing ease. The differences are extremely noticeable as well - there is no need to be concerned with whether or not something is too subtle for the equipment you are using. This is not to say subtly cannot be achieved here, it is just not the only game available. All in all, the sound are interface are a 10/10, and are of the level of professional quality plugins (the few that I have used anyway).

Why I will likely never use this in a true production situation:

The latency is a killer. Something like 49ms on my computer (my very fast and powerful computer), and the compensation required just isn't worth it. I don't know enough about DSP production to have any sense of what the source of increased latency is, or why it might not matter as much as think it does, but until that gets fixed, this is essentially unusable for me. I've only used two plugins in my life that caused latency that was immediately, and unmistakably audible, and they were both great plugins; but they damaged the mix so much that I can't compensate for it in my listening.

Bottom line: Killer plug-in. Too much latency.

Developer edit: Have you noticed the knob called Delay? You can use it to bring the latency down to about 17 ms. If you're willing to compromise on resolution you can even bring it down to about 6 ms. Every linear phase equalizer introduces delay, at least SplineEQ allows you to adjust how much you get as a trade-off between CPU usage, latency and frequency resolution (and it remembers your settings permanently). It can't get much better than that for linear phase equalizers, which makes your comments and rating sound like a misunderstanding. Furthermore as someone else pointed out the main use for linear phase equalizers is in mastering and final mixing.

User Edit:In taking the developer and other user responses into consideration, I have revised my rating. I do think this is a d*mn good eq. However, I have used linar phase eq's that don't introduce noticeable latency, Voxengo and Electric-Q to name a couple. I am no master in the music production field, and as I said, I don't know why the latency is introduced or why it might not matter, but it still is what it is. I will play with the delay some more. When using it the first time, I found that the latency was not improved by as much as you say, but I can't remember exactly. Still, if I can get it below 10 or maybe even 15ms or so, for sure it would be at the top of my stack.
