No worries if i end up using it full time i will pay for a license. One question or suggestion perhaps you can create a consumer oriented version that works through an APO? That way it will be system wide and allot easier to use for other kinds of applications. I know you can use stuff like virtual audio cable but an APO is a much cleaner and easier solution for a consumer.

We're thinking about making an app which sits at system audio level. Should make routing audio trivial. There should also be a switch to make going from headphone calibration to speaker calibration much easier.

Honestly, I think a lot of people should be able to look at the publicly available FR plots and the vast swath of internet knowledge and come up with an EQ curve that works for them. Not to detract from your software; the plugin has a great UI and toolset. As to whether an EQ curve can be proprietary IP......  :-S :-\ :-X

Implementing FIR filters isn't that hard, but developing them so they don't sound like shite is less than trivial. Our first attempts sounded like spoons being banged on old radiators - crazy pre-ringing.

Most impressive. Your's doesn't have that low-fi grain/mud and lack of life that every other eq (or any dsp) has pro or consumer i have tried. I'm religious in this and usually hatered comes from me regarding dsp-s.
HD800 preset though coupled with my cranium + some rug liner mod have way too much bass and some weirdness in upper treble.
The upper treble thing is at least partly due the mod (guessing), though some dizziness is unlikely due to the mod.  Bass is easy to fix with the bass slider.

Point by point:
- more depth and frontal projection in headstage, somewhat less width and slight confusion in imaging (needs verifing). Makes me wonder whether some cross-feed is being used?
- tonal balance is definently closer to Genelec 8050 than before. I don't know yet what to make out of this, will listen more.
- I like the bass quality. Though this is entry-basshead levels of quantity, generaly not my thing, but at times :D....
- No apparent lack of dynamics and fluidity.
- Treble is sometimes sizzling and slightly grating.
- Maybe some slight microdynamic compression
- Aids the mod in shelving excessive brightness
- Less shouty in some tracks mic-ed closely
Will report back with more complete impressions. Definently recommend to pirates!

Forgive me for being thick, but where do I open the trial version on a PC after installing?

You need vst host program, JRiver has it by default, Foobar needs add-in host.
Go to Program Files (x86) in Windows--> VST Plugins through the host menu. Activate. Done.
Mac players that have vst host should find AU plugin by themselves.

You need something which is able to run plug-ins. If you use Foobar2000, VST Wrapper is the most painless. On Mac, either JRiver or Soundflower/AU Lab.

Ok sounds cool!
Listening to some Trentemoller and that phat bass on the 800 holy fucking shit.

Not my call to make, OJ. Pretty sure, if you redraw our curves by hand from the plug-in and run them on another EQ tool, you'll be 80% there, depending on how good the EQ's dsp is and how steady your hand is.

At the same time - generating these correction profiles takes time and money. We buy the headphones we measure and every profile needs to be made from averaging out many samples from the same model to account for variation. Every measurement needs to be analyzed by an engineer to determine if we're not correcting for measurement artifacts. Then we do rounds of both sighted and blind testing to see if we can assure that you get the reference sound we promise. There are batches of headphones which we bought, measured and they didn't make to public release. Mostly due to reasons related to unreliable sealing or severe resonances.

I figure most audiophiles are tweak-o's and would like to do things themselves, but, as I said, your plug-in offers a easy retard-proof way to "fix" things. Even if there are detriments to one size fit all approach.

But excuse me, I'll let the thread hijack continue :)p8

Mayhaps you guys could include a OW preset curve so people could correct their headphones to the newest FOTM curve
