Is 8 analog outputs to multichannel PCM or even DD over HDMI in real time, possible?

[PHD]

Hi


A friend at work has a working Lexicon DC-2 which I can buy for $200. I want to connect my Bluesound node 2's SPDIF output to the DC-2 SPDIF input and set it to Logic-7 mode.

Now, my Denon X4800H doesn't have multichannel analog inputs.

So, I was thinking, is there a multichannel analog to digital on-the-fly converter/encoder device that can take 8 analog channels, encode them into a multichannel PCM, and output them via HDMI, which would support 8-channel PCM?

Perhaps it could be possible to do this using a PC with an 8-channel soundcard that can do l time encoding to even Dolby Digital or DTS?

Is this even worth the trouble? I'm very curious to test the logic-7 upmixing capabilities.

I'm even open to an offline solution (sound card with 8 channel analog inputs that can capture them at once as 8 different wave files which I could later encode as LPCM using an audio editor software)

Thanks

Your Denon has Dolby Atmos, DTS:X, IMAX Enhanced, Auro 3D, Dolby Surround, and DTS Neural:X. Do you need Logic-7?

I was always curious about Logic-7 as a 2.0 to 7.1 upmixer. Especially in the older Lexicon processors, where you have many ways to tweak the upmixing effect.

I really don't understand why the license to apply Logic-7 was never acquired by other brands if it is really that good as anyone who tried it claims...

That should work although there will be some latency. https://docs.pipewire.org/page_man_pipewire-pulse-modules_7.html has some info on supported compressed formats like DTS, but isn't entirely clear whether they're all capable of encode as well as decode.

I doubt it. But even if there is it will be a royal pain in the ass to make it work properly, with decent quality.

On the other hand...

Your Denon can also do this with a number of up-mixers, including Auro 3d - and I'd be surprised if the Lexicon - with its 25 year old tech - can do a better job of it.


My personal opinion - don't waste your time on this just to scratch a curiosity itch.

Lexicon, and then Harman, was busy using it as their special sales sauce....

And by the time it would have made sense to let go of the exclusivity, Fosgate had developed PLII and sold it to Dolby... and Dolby then as now dominates the market.

A missed opportunity.
