Introducing OPRA, a powerful new headphone toolkit for Roon and ARC

[watchnerd]

Sorry for the slight necropost!

They do use AutoEQ, but in addition to that, OPRA is also using the EQ settings I publish here: http://reddit.com/r/oratory1990/wiki/index/list_of_presets
As a reminder, AutoEQ does not use my EQ settings - it uses my measurements but the EQ is calculated automatically. OPRA is using my actual EQ settings (the same ones that are being published as a PDF)

They are paying a license fee - which helps me build my own lab (I have switched jobs and do not have access to the previous lab anymore)

It's the Harman Target, specifically the curve from the 2018 paper.

If I look at the K7XX (screenshot upthread), I see two different curves with your name on them.

His? Who is "he"?
EQ related just to brand and model says nothing about the target curve. EQ as implemented by ROON is almost useless as you don´t know what it is aiming for,

One of the curves for the AKG K7XX is labeled the Harman target curve.

See screenshot upthread.

Yes, because Opra uses both my own EQ settings (the same ones found here) and AutoEQ (which automatically calculates EQ settings based on measurements it takes from various sources, me being one of them).

Opra uses my EQ settings under license. They're the EQ settings I made.
AutoEQ takes my measurements (unlicensed) and calculates EQ settings from that.
