Possible solution for DTS/Dolby/Atmos+eARC+HDCP to AES/EBU via Dante? (for Okta 8 etc)

This is more or less what I am after too. All I need is a simple eARC to 12 channel (7.1.4 setup) converter / sound processor (after all the downmixing/upmixing/no-mixing). All digital and no analog in or outs. It's hard to find a single device that has 12 output ports (either Dante or ABS/EBU). Did you find something?

Arvus H1-D fit the bill?

That is the closest to ideal, but now I need an additional network switch to individually route channels to the speakers, right? I was looking for the convenience of an all-in-one box.

Me too.
These are the processors that I'm aware of that decode and output multi-channel digital audio.
The 8 channel units just extract digital audio from HDMI.
I believe there will be a new option in the near future - the Audio Control Hyperion DPR-16.

Yeah looks like Hyperion DPR-16 will be it. I had emailed them asking for price. As expected asked me to wait :)

If it doesn't the product listing is extremely misleading.

I assumed all that listing is because it does. Afaik Dolby Atmos cannot be transmitted over anything but HDMI due to licensing. So if the output is anything but HDMI, you have to decode and convert.

It seems the SW42DA is available B2C now, which is great. I've had to pause this quest for now but I'd love to hear if anyone uses this for its Atmos breakout for home AV. Be very curious to know if the proposed setup with something like the Sonifex Dante/AES67->AES3 would introduce much latency and make it unsuitable for gaming, since game support is wider than I guessed. PS5. Xbox.

The Arvus H1-D as masterhw points out is also an interesting solution, if a bit painful on the wallet.

This is great info. Didn't think the thread would go this well! I'm still exploring ways to shoehorn the Okto into this niche, mind.

A frankenstein decoder + Okto DAC8PRO setup would have 118db SINAD and 122db DNR if going by amirm's measurements. A single unit has only has 8 channels, mind. Although as noted earlier in the thread if you have an Atmos decoder with >8ch AES3 output you could pair DAC8s and keep clock sync. If money was no object I'd get an Arvus H2-4D with 2 DAC8PROs, then do bass and room integration using REW and the aforementioned AVDSP_DAC8 firmware available for the Okto to apply necessary HPF/LPF and delays. This uses the onboard XMOS XU216 but is limited to IIR filtering, no FIR. My single unit is currently doing this for 4.1 and maintains its max sample rate of 192khz through processing; this might drop to 96 depending on how much processing is needed in your DSP program so an asterisk would be needed in that column. Shoutout to fabriceo, it's very cool stuff! I've attached the DSP firmware config I'm currently using, it's fairly simple at the moment but RTFM always applies.

I'm not sure if this idea should qualify for the table :p

The datasheet and manual are not at all clear or explicit about that.
My suspicion is that's it's an HDMI audio extractor like the Audiopraise Vanity PRO, and needs the source to do the decoding to multi channel LPCM.

The SW42DA does decode Atmos in up to 5.1.4 or 7.1.2 and present it on Dante.

It’s not the first product to do this it’s just that all the others which can do this such a JBL Synthesis SDP-58 or Storm Audio ISP Evo are tremendously expensive.
 
I spoke to Genelec (Marcel Schechter) regarding buying their digital active speakers and he right away mentioned the difficulty in finding fully digital sound processors in the market. But he said he is hopeful more products will come later this year or next year.

Most of Genelec's customers go for analog input. Marcel said he even as a trained user, couldn't find any difference between digital path vs analog path (even though analog signals will be converted to digital at the speaker end).

Arvus has a product in the pipeline, so has AudioControl (Hyperion series). Best to wait till 2026.

Given the price of AudioControl’s current top end products the Hyperion is going to be more towards the already available Storm audio end of the market.

I don’t hold out much hope for the Arvus which leaves the currently available Bluestream box.

I think you're right, but the question that HAS to be answered about the Bluestream is whether it needs Bitstream or LPCM audio over HMDI to do what it does.
 
I was referred to this thread from my own thread where I'm dealing with somewhat similar problems (i.e. going from HDMI eARC Dolby/DTS to digital AES/EBU or at the very least balanced analog).

The SW42DA looks like an extremely interesting product; even just the fact it has balanced analog outputs is already interesting (alternatives like the Marantz AV10 are 5 times the price), but on top of that the AES67 output makes it furiously intriguing. I hope it works as well in practice as it does on paper.

The only gap with a SW42DA-based solution is EQ/room correction. Are there any products out there that can do advanced parametric EQ/routing/mixing on a AES67 stream and then re-output AES67, AES/EBU, or even balanced analog? I could just slap a miniDSP on the balanced analog outs but might as well stay in the digital domain as much as possible. The Nuprime-X H16-A just mentioned boasts room correction support but it's not clear how customizable the parametric EQ is.

I am not optimistic about the Nuprime's room correction support but my plans are to feed it (or one of the other options) into Jriver on my PC where I can apply DiracLive and output the signal to a Hapi II DAC via Ravenna/AES67. In your case, you would send it to the speakers of your choice.
