I'm using this EQ for headphone curve correction.  It's the only one i know that is able to import csv files.  I am able to use APO headphone profiles with more than 600 EQ bands.  CurveEQ is indispensable in my chain.  I use it every single time I mix.

I have various match EQ plugins including the one in LOGIC and the one in Ozone but this one is by far the most useful as I can export my EQ curves as .CSV files.  This means I can use them in a hardware DSP, where for example I don't want the latency.  I can also import a .csv curve, which means I can use my calibrated microphones, import their respective curves and create a recording with a totally flat response.  I can also create .csv curves Room EQ WIzard, which means I can use this as a measuring tool, then get my EQ into my software, where it is preferable to having it in hardware.  So I have created a hardware version of the ARC curve for my room on my master output.  And I have the EQ curves of various signal chains in AU/VST.  The one feature I think is missing for me is a better understanding of how the Q works on each filter band.  It would be useful to have an EQ calculator for those times when you see a fairly simple curve which you could dial into a parametric where exact EQ is not so critical.  An example of this is that I was trying to match two guitar pickups and only had limited EQ to do it.  I measured them using Curve EQ and I could see a fairly simple curve.  It would be nice to have an overlay showing potential settings for 2 or 3 band EQ that could be dialled into hardware to get a similar sound.  I am sure there is a formula somewhere to approximate EQ with a few bands of parametric but I probably wouldn't understand it ;/)

I started using your plugin, on a mastering job the other day, and realized how incredible the linear eq is, it's so smooth and doesn't just work, but the first thing I noticed was it sounds incredible, it has a ora to it I can't explain, and competes with some of my not so inexpensive hardware eq's we use, it's a incredible plugin, and worth every penny, thanks for the awesome Plugin..  We master about 5 projects a week, and this has become a go to plugin

Voxengo Curve EQ is "must have" plugin IMHO.  Spectrum comparison and analysis in modern music production is crucial.This plugin is definitely the best in this area (I've tried a lot) I'm really 100% sure about all eqing I do during mastering sessions, cause I analyze a lot and compare a lot using Voxengo Curve EQ.

I have all kinds of very expensive software, but still I use a lot of Voxengo plug-ins, some of them are really unique.

I purchased Curve EQ yesterday and I'm hooked.  I don't wanna do another job without it.

What sets Curve EQ apart from the competition is not that it perfectly shapes one spectrum into another, there are more that can do that, but the fact that one can't hear that it has been done.  Even huge corrections don't seem to bother the sonics at all.

This makes it a perfect mastering EQ also if you're not after copying another spectrum.

Well done Aleksey

I feel like saying thank You for giving CURVE EQ the audio world.

I am using CurveEQ for several situations in mastering.  But for some time I was also working heavily on changing listening setups on lower SPL levels to be used in mastering as the most important first step is to find the right spectrum balance for every music in every genre.

Due to the strong effect of ISO226/Fletcher Munson I found CurveEQ as THE tool to be used in a mastering setup to make perfect basic EQ decisions on 10dB! lower listening levels from normed reference SPL levels (79 to 85 dB SPL), which are sometimes really annoying for sensitive ears.

CurveEQ appeared as the only tool to manage this job accurately!

Curve EQ was the very first "match" EQ plugin I ever bought and it quickly became a real "go to" plugin for me..one I know I can depend on while mixing / mastering, as well as during the pre-mix sound design phase.  The information Curve displays, along with it's "matching" feature, enables sounds to be crafted quicker than any other EQ plugin I've used in the past.. and I don't intend buying any other any time soon.

I have had a 'bedroom studio' for the last few years and when it came time to look for mixing and mastering tools outside of Logic's own I did a lot of research into the different brands on the market.  Voxengo's was a name consistently associated with high praise.  Having bought numerous plug-ins from you I attest to the robustness, usability, elegance and effectiveness of the Voxengo tools and the audible improvements they made to my music.  The price, when looking at that of the competition, seems pretty cheap.

I use Crunchessor (powerful all-purpose compressor), Drumformer (great results) and Voxformer, Varisaturator, GlissEQ and HarmoniEQ and the smaller ones, like StereoTouch (so good), Warmifier (very subtle when used correctly) and LF Max Punch (instantly rewarding).  When I master I always use CurveEQ (brilliant design), Soniformer and Elephant.

As an amateur, it's hard for me to appreciate just how good these plug-ins are, because I've not tried a lot of the comparable tools from other companies, but as Voxengo always does the job in the way I want, I've no desire to look for any replacements.  When I used Elephant, I knew I wouldn't need another limiter; it doesn't add any colour to the mix and it's incredibly powerful.  The entire mix is simply elevated, louder, with no apparent negatives.  The only one I have no idea how to use is Soniformer, but the presets are really solid, so I don't feel the need to investigate further.

The saturation, EQ and compressors in Voxformer helped me fully realise what my voice could be.  I had no idea my vocals could sound so full and warm until I used it, and now my singing has matured to match that sound so well that I don't even need to dump loads of effects anymore, just any quick preset on the Voxformer and there you go: thicker, sunnier, glowing.

I'm so stoked I came across this site, and I will definitely get the Polysquasher in the sale this summer.

I use your EQ, SPAN, and Voxengo Analogue plug-ins all over my own music.  Span Plus alone is absolutely essential for both tracks and masters.  When it comes to Tape Simulation, there isn't a better plug-in out there than Tapebus, and I've tried countless, plus the Delay portion of the bundle is one of my all time go tos.  I look forward to trying out more, amazing work my friends!

I just want to comment on Voxengo products we use here in the studio.I would say lately they have been the "go-to" plugs we've been using.The Curve EQ,Soniformer,Elephant have replaced all the "big name-big price" plugs that keep getting all the talk.Extremely warm,versitile, and analog.The compliments I've been receiving have been satisfied clients and "How did you get that sound?" We are lucky to have a company and a creator
