I have tried playing with the proposed EQ on IF for the HD800s.  A little boost in the bass of around 3-5db (more db towards 20-30hz) is acceptable, as is EQ'ing down some of the treble.  I think +6db at 1.5khz is too much though.  The most I EQ'd up the upper midrange was 3db.

So you're hearing that same issue. That's clearly too much boost there for the HD800. Maybe OW curve would sound better with other 'phones. AKGs perhaps ;)

Anyone have a recommendation for a VST plugin?

Stupid question to reconfirm: Do the IF measurements actually use the OW compensation?

No, Tyll did an article where he applied the new OW curve to all the raw response, but everything in database is not OW corrected

Got it....

My quick assessment: WTF the bass? The did reference Harmon speaker/room have 12db, 8db, and 4db modes at 22Hz, 45Hz, and 90Hz?

Other consideration: How equivalent is Tyll's measurement system to Sean Olive's measurement system? This might be crucial. For example, maybe Tyll gets a better seal than Olive.


P.S. Oh shit, I forgot that I had commented on it about 1.5 years ago and said the same thing.

Someone more familiar with OW's work can correct me, but as I understand they used a fair bit of listener polling. Listeners wanted 4dB boost throughout bass region.

Did the people they poll look like this?

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.
Yes that would make the transition easier as now in I need to go into JRiver DSP and fuss.

However using the wet/dry control can also be handy…
And the more I learn of the plugins functionality the more 'handy' it becomes.

It would be even more handy if the headphone correction could be toggled on/off while leaving the other 'reference curves' active.

Can the Sonar Works plug in be accessed through jRiver on PC? I just can't seem to figure out how this works.

Yes, once you have it downloaded go to DSP Studio > manage plug-ins > VST > find the .dll file
