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

Early Access
1

Hey Everyone,

We’re excited to announce the arrival of OPRA (Open Profiles for Revealing Audio) in Early Access!

What is OPRA?

OPRA is an open, community-maintained GitHub repository delivered by Roon that gives audio experts and sound enthusiasts a trusted, collaborative platform for precisely crafted EQ profiles that optimize a wide range of headphone models.

OPRA represents the first comprehensive effort to establish a reliable, community-driven source that facilitates routing headphone EQ profiles directly into software, providing an accessible space for headphone enthusiasts to gather, explore, and contribute.

Today OPRA contains EQ profiles for hundreds of popular headphone models. We expect that number to grow as people around the world leverage these profiles to improve the performance of their headphones and contribute their own profiles to OPRA. We’re already exploring collaborations with key figures like oratory1990 and will share more on that soon.

OPRA in Roon and ARC

We’ve seen innumerable Community posts from headphone users and aspiring audiophiles asking for equalization advice and expanded EQ presets like the ones provided by Audeze.

Our new Early Access build integrates OPRA into Roon, making these expert-created profiles easily accessible to anyone looking to get better sound from their headphones. Say goodbye to the hassle of manually entering EQ curve parameters; optimized tuning is just a few clicks away.

You’ll find the new Headphone EQ filter preinstalled in MUSE when you launch the latest build.

Testing OPRA

Headphone EQ is available as part of MUSE in Early Access builds of both Roon and ARC.

Please be sure to browse the profiles available in OPRA, and try them out with the headphones you use and any other MUSE functionality that’s part of your normal listening experience.

Let us know about any issues, questions, concerns, or bugs you run into.

How OPRA Works

Navigate to MUSE in Roon or ARC, enter the Headphone EQ filter, and search by model name or manufacturer. You can also use the manufacturer logo grid to browse by model name. Click a model number to see and select EQ preset offerings.

The preset you choose will appear in the parametric EQ grid display, providing a visual reference of the tuning that’s being applied.

To remove the preset, press CLEAR. In Roon, use the breadcrumbs above the headphone model name to return to the model list for the brand you selected or to navigate back to the complete list of manufacturers. In ARC, select CHANGE PRESET.

If you feel that a particular preset needs additional tuning, you can click the arrow shown on the graph to save the curve to your EQ presets, where you’ll have full control of all parameters.

With OPRA, enjoying better headphone audio quality is easier than ever before!

Very nice @mike but could we have separate zones for headphones when using the same Roon Endpoint for either speakers or headphones? Here different DSP profiles are needed for either speakers based on REW measurements & convolution filters or headphones using the OPRA profiles.

I often forget after using headphones with a DSP profile and then panic that my speakers are broken, but it is just the wrong DSP profile, that needs switching over. The Roon Endpoint is the same Naim NDS Reference Network player with SonoreUPnP Bridge.

Looking forward to trying this out. Will compare Audeze’s own against OPRA as well for my Audeze. It’s been a few years since I used Sonarworks but preferred Audeze’s tuning to Sonarworks. I had a few headphones that were supported by Sonarworks, but their signature house curve didn’t quite fit right for my taste. Excited to see how far we’ve come. Time to dust off the headphone collection. :slightly_smiling_face:

Haha that happens to me all the time at one of my desktop zones where I use the same endpoint for both speakers and headphones (with Audeze profile) and find it off for awhile until I remember to look at signal path and change it.

Hi @mike

A feature well worth testing. Updated fine. Within 5 mins I have two EQ profiles set for my current main two sets of headphones, those available on AutoEQ.

For Arc via carplay/Android Auto, known car brands EQ profiles sound possible now :wink:

OPRA, may need a brainstorming session on the name (again) :face_with_peeking_eye:

You’ll get headphones for the zone’s line art when the filter is active, so at least it’s harder to forget when this stuff is active.

But understood on this:

We’ve talked about this kind of change quite a bit, but I can’t commit to when we might overhaul how zones and devices interact. For what it’s worth, I really want it too.

I had been thinking the other day about whether some kind of “quick switching” might be good for DSP profiles :thinking:

With my Mojo2 I’ve got the choice of two pairs of cans. I’ve just saved two presets and it’s easy, quick enough to swap between them in MUSE.

Can’t see “Headphone EQ” on my Desktop Roon. On ARC, its OK.

[Update : Solved]
My RoonServer was unhopely “Production”. It is OK now on the EarlyAccess.

As I am already using EQ, I am not quite sure where the benefits with OPRA is?

What’s the benefit of having a separate repo instead of using e.g. the AutoEQ GitHub repo? Seems like you’re reinventing the wheel.

9 posts were split to a new topic: OPRA in the Roon phone app?

It’s easier and quicker for people who don’t use EQ or wouldn’t know how?

It was enabled listed in the filters for me automatically, but it is not in my Add Filter list either, so I don’t know if I could re-add it if I deleted it.

Version 1470 on iPad and rock here, don’t have this option

17

That’s because 1470 is the current regular Production release and OPRA was just released in Early Access with these build numbers:

I’m sorry, I found my Roon Server was switchwed to “Production”. Now it backed to EralyAccess and I could find a “Headphone EQ” fiter. Solved!

The production releases are announced here:

You can even set up a notification for this category whenever they post a new update.

Ignore the Early Access announcements from here (or be aware that you won’t get them):
