AVR solutions that output room correction/EQ over HDMI?

[Donrod4]

I’ve tried searching high and low for something like this, and know it’s somewhat a niche thing/idea, but have been out of the home theater game for a while and wasn’t sure if this is a thing.
I love to tinker with stuff, and don’t mind if it’s unorthodox to pull off, but I’m wanting to find a way to apply room correction and EQ and output it via HDMI E-Arc/Arc to a soundbar (Nakamichi Dragon). Waiting for house to be built so I can expand back into a full HT system, but mainly looking for something to mess around with in the mean time.
Wasn’t sure if there was an AVR solution that could dissect Dolby Atmos content for the channels that the Dragon has (“11.4.6”; really 11.2.6 in stock form, but I’ve added my two Exodus Audio Maelsteom-X folded horns to the sub stage and have the stock subs HPF’d to 70hz to act as more of a full front stage of the bar) so I have EQ/room correction on the horns, but want to apply that to the soundbar and all its channels as well. Is this something that is possible? I don’t mind spending some $ to have a great Atmos receiver/processor for once the house is built, but was hoping there was something that would allow me to do what I want with the soundbar as well while I wait.

First, welcome to the Forum!

I don’t see how this idea would work. Assuming the AVR’s HDMI output would include the room correction, it would only work with signals coming from the AVR. IOW, signal sources would have to be plugged into the AVR. Your soundbar is getting its signal from the TV.

Is this Wayne from HTS?!
And yessir, sound would originate from AVR, either with an e-arc from TV to receiver in for say tv app steaming options, or inputs (blu ray player/ps5/etc) being sent to AVR over e-arc and just video being send to TV from AVR. I know it’s an odd an unusual request but figure if I’d be spending thousands on an AVR solution, I’d try to find one that would work with a soundbar that has all the “proper” height and surround channels given its footprint, but needed to dissect and apply DSP to the HDMI signal it was receiving.

There are soundbar solutions that have Dirac built-in... the Klipsch Flexus Core series!

The only other way to achieve what you're talking about is to use a passive soundbar and feed it using an AVR.

I see what you're getting at... interesting concept, but in practice, the way ARC works, the decoding is left to the soundbar.

I had a Flexus 300 and the Dirac worked pretty well, but the bar was lacking. One tweeter in the bar led to it being either shrill or dull; couldn’t stand it. Did like the fact it had a dedicated pre-out however. I do have a passive definitive technologies soundbar I could break out with a Marantz AVR, but no surround options viable currently or room for rear of the setup (SVS mains and front/rear center, caught a sale on the Tritrix speakers few years ago, so front and rear surrounds are those, ceiling too high to install other speakers there in this house). Was mainly looking to tinker with what I had currently, albeit very unusual I know. Maybe I can get with an audio engineer buddy and we can make a computer program to decode the audio channels, run REW through that, and have the audio pass through there for EQ/corrections. I’m not smart enough for that stuff lol

This is probably no help, but MiniDSP used to make Nano AVR and AVR-DL with Dirac. It had HDMI in and out. Not ARC OR eARC and it had to be fed PCM, so no atmos.

........but they did work well. Anyone looking for a NanoAVR should let me know. I have no use for it.
