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

[Mike_O_Neill]

@Billy_k

It baffles my mind that they have implemented a feature for headphones, which are more often than not related to mobility,

Maybe speak for yourself, there are many users here who are 100% headphones. I have been for at least the last 12 years since I retired.

There are many advantages to using headphones , if you have restricted yourself to Cell Phone & Ear Buds you have been serioulsy missing out

Hi, This is sound very good. I did try to found OPRA in Muse without success. There is only AUDEEZE option that I can see. Can someone provide some guidelines? Best.

[Neil_Small]

I know many people that have more invested in over-ear headphones than most do in stereo gear. This is a huge win for Roon.

Well, are you using Early Access updates for testing?

Unable to access OPRA in Muse (ref#V5WXYE)

Are you using the Early Access update track? Then you should be posting this in the Early Access area. If you are using regular production updates, then you don’t have OPRA yet because it has only been released to Early Access for testing.

Thank you for the information. In fact, Early Access Program is new for me. I got the information on the way to install the Apple app to get access to Early Access Program. I will install it and I will provide feed back. I did set the Headroom for my Audeez LCD X and I can hear the improvement. Thank you.

Remember that you have to update server and control apps (on PC and mobile) to Early Access. If you don’t intend to keep testing Early Access (and deal with the occasional issue), it’s probably better to wait a few more days until it’s released regularly anyway. It’s usually only 2 weeks or so until Early Access updates get moved to Production. (Depending on how many bugs are found and how the feedback is in EA).

[Gaetan_Patenaude]

Thank you for the tips. I will wait in order to avoid local network issues. Since it is working with my AUDEEZE LCD X I can expect to get interesting results with my other headphones.

You can already add PEQ manually, OPRA offers a degree of convenience and simplicity.
I personally prefer the Oratory1990 presets which you can get here;

https://www.reddit.com/r/oratory1990/wiki/index/list_of_presets/?rdt=61009#wiki_full_list_of_eq_settings.3A

There are other sources of PEQ settings, should you feel your headphones need them, not all do IMO and some actually make headphones sound worse, again IMO.

Winfrey?
Like British rhyming slang, you need to be aware to get it.

Think on the following, @mike.

When an EQ preset has been chosen, the signal path display should be enhanced to display the name of the preset, possibly as a widget that collapses the individual filters in the pipeline. I suggested this many years ago as there’s not enough information in the signal path display to distinguish between presets that have the same filters but different parameters. Displaying the preset name solves this.

This feature would be useful for OPRA users as a place to find the name of the OPRA profile that’s active in the signal path, and if expanded, which particular filters are in the pipeline too.

Thanks,

OPRA certainly appears to be a great new Roon feature. Quite a bit easier to use than the convolution filter method. Now I’m just waiting for filters for the Drop+Grell OEA1 and the FiiO FT1 headphones to be added.

Bravo Team Roon!!!

[Michael_Harris]

Absolutely agree with this statement.

It has made it significantly easier to swap between headphones and also different filters for the same headphones when they have multiple options available

[Enno14]

It is a very nice and helpful feature. Well done!

[Burkhardt_Petermann]

Mmh, I don’t see any advantage in using OPRA against the previous filters.
If you use a mobile as remote, you’ve to save for each combination endpoint/headphone (I’ve a lot of them ) this as preset and this work will be done (for me) only once, until a new headphone or endpoint comes up…
For endpoints, which are using HQPlayer I don’t use any DSP in Roon and so also not OPRA, but this is another point…

@Burkhardt_Petermann

The advantage is that it’s made it easier to use headphone DSP for users who would have had no idea how to set it up previously by finding a third-party site for measurements, copying the EQ data, and entering them into MUSE.

[anon96160794]

I doubt I’ll use it, I’m not planning on buying new headphones and the 2 headphones that I feel need EQ have presets already added by me manually, but for anyone who’s not tried PEQ it is a quick and convenient way to try it

[Jazzfan_NJ (Listening to JAZZ since 1972!)]

I believe that one could just save the OPRA settings as a (named) preset, which is exactly what I’ve done in the screenshot below.
Preset name: test
Crossfeed: enabled
Headphone EQ: enabled with filter for Dan Clark Audio Aeon 2 Closed (measured by crinacle) selected

[Burkhardt_Petermann]

Sure, this can be done for all used DSPs and so it’s nothing what’s new and a must, if you’ve multiple settings and using as a remote a mobile, what I’ve written in my last posting.

[miklats]

Thank you for that, This is a great feature and effort.

[Calum_Mackay]

As some others have noted, the OPRA presets appear to have a headroom adjustment built in, resulting in reduced volume when compared to MUSE disabled, although it’s not shown as “headroom management”.

That seems to reflect the overall gain_db value in the OPRA data (not the per-frequency band value), e.g -6.3dB in this example:

{“type”:“eq”,“id”:“sennheiser:hd_660_s::autoeq_oratory1990”,“data”:{“author”:“AutoEQ”,“details”:“Measured by oratory1990”,“type”:“parametric_eq”,“parameters”:{“gain_db”:-6.3,“bands”:[{…

That seems right: if I add a preset with just -6.3dB headroom (and no other changes), and compare that to the OPRA preset above (which has no explicit headroom set), they sound about the same volume.

It would be nice if there was a way to do this, within the MUSE headphone EQ settings, to make it easy to compare the OPRA presets with no MUSE. You can’t just disable headphone EQ, since that will result in no headroom and a much louder sound.

But since each preset, per headphone, has a different overall headroom adjustment, that’s hard to do.
