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

[Tim_Woodward]

Ah OK I can see them all now… the difference between all these adjustments and Resolve’s are quite profound. He doesn’t seem to see any reason to pull down the 2900Khz band at all, whereas all these others do quite a lot - the result is almost a phase shift in tone, a thickening of vocals and lack of air. Resolve’s EQ is thinner by comparison bit far more air - but sound more real?

Anyways, maybe I should shift my fun experiments over to somewhere else as this isn’t really on topic!

[CrystalGipsy (Resisting the flow!)]

Depends on how the measurements were done and what they used to do them all of which can affect the outcome.

[Henry_KARJALAINEN]

Same here. Not functional in the Android app.

[BlackJack]

Modify EQ from Android phone

You can use DSP presets.

Thanks Roon.
Great addition to my mobile @home set-up using my Android mobile phone with Roon Arc + the DAC dongle of my choice (and headphone).

[Bruno_Winyle]

I try check this new feature in Roon Arc and Samsung Buds2, Sony WH-1000XM5, Bowers & Wilkins PI5. I feel a reduction in volume and a reduction in bass. Should I turn off the equalizer after turning on the Headphones EQ settings ?

The OPRA EQ (desktop Windows 11 + iPhone 15 Pro) settings that I have don’t show up in ARC (iPhone 15 Pro). Nothing

[Dipper]

I may have misunderstood but are they not there if you click on Headphone EQ

@Torben_Rick

The OPRA EQ (desktop Windows 11 + iPhone 15 Pro) settings

As far as I understood, the settings done on PC/Tablet for Roon Zone pre-sets are for the Roon Remote app, or, other Roon endpoints, not ARC. You need to setup ARC in ARC in the Headphone EQ.

[Torben_Rick (Torben - A Dane living in Hamburg - Roon Lifer)]

I think you are right @Rugby

Than it easier to use Roon Remote app instead off ARC when not at home

@Torben_Rick

Roon Remote app

is only for local playback, it doesn’t work outside the home network. (aside from some Tinkering VPN cases).

@Rugby

Yes, it works just fine outside. I use WireGuard-VPN with my router so I can use Roon Remote app.

Tinkering - no

Roon ARC - FRITZ!Box - VPN

If you are using an FRITZ!Box router - in my case 7590 - and don’t want to use port forward, there is a very nice solution that works just fine with ARC, You just need to setup WireGuard-VPN: [image] and than install WireGuard-VPN on your phone. If you than test the connection it will show Roon ARC is not ready: [image] But ARC works just fine and you have an VPN connection. Torben

You only want one EQ in the chain, the Sony (or whatever) or Muse / OPRA.
For BT headphones I’d just use the EQ in the headphone app and save OPRA for wired equipment.

[CrystalGipsy (Resisting the flow!)]

Using presets for your specific phones will reduce bass if it’s too high for the Harman curve that is being used as the baseline. It will bring it down to its recommended levels as well as adjust other areas where the heaphones fall out this curve preference. The Harman curve doesn’t appeal to everyone so it’s horses for courses . To prevent audio clipping when DSP is applied as some frequencies will get boosts the overall digital level is lowered to prevent this, thus giving it more headroom before it reaches peak 0dbfs.

If you have other eq in play via your headphones own DSP then use that or just use OPRA but not both. Use what pleases you the most. Not all like headphone eq at all.

@dabassgoesboomboom

can we please get ability for separate Left and Right channel EQ?

Not sure if you’re asking for separate left/right EQ with the new Headphone EQ (OPRA) or whether MUSE supports left/right EQ.

For MUSE, you first create a Procedural EQ, then create 2 separate Parametric EQs inside that Procedural EQ. You restrict one of those inner Parametric EQs to be left-only and another to be right-only.

I’ve managed to apply separate left/right EQ this way (even on top of my headphone-specific Parametric EQ) to apply audiogram compensation.

OPRA and ARC in general, both when away from home. No procedural DSP with ARC?

For Roon at home can be done

[desbiss]

Not sure if it’s already been requested, or if it’s possible… but my IEMs weren’t listed under their brand. Is there a way to add them to a future OPRA EQ ‘wishlist’? Mine are Oriveti O400…

[Grasshopper (\m/)]

You might need to send your IEMs to one of the people doing the testing, they include professionals doing this work in their spare time.
They don’t have access to all IEMs on the market.

Have a look at the autoeq website for contract information or Reddit in the case of contacting oratory1990, who is my personal preferred source of measurements.

[SukieInTheGraveyard]

I’ve had quick look at what Oriveti’s have been measured. Jaytiss has measured both the OD100 and OD200, so they might be your best bet in terms of asking about the O400.

ToneDeafMonk has also measured some Oriveti’s.

Measurements only transfrer over to OPRA if they’re added to AutoEq, as far as I know.

They both hang out on various headphone forums, e.g.

ToneDeafMonk

Jaytiss

[desbiss]

Thanks @SukieInTheGraveyard and @Grasshopper! To confirm my understanding, essentially I have to EITHER send my O400 IEMs to someone who can measure them… OR, rely on someone who has provided prior Oriveti measurement, in hope that they have a pair of O400 IEMs that they could measure and submit to AutoEq…?
