Possible solution for DTS/Dolby/Atmos+eARC+HDCP to AES/EBU - via Dante? (for Okto DAC8PRO etc)

[john61ct]

Noob here, but my opinion from extensive reading.

HDMI sucks for audio, extract it ASAP and use well established standard transports.

I2S is only suitable between boards within a single enclosure over short distances, as in a few cm.

For cost effectiveness, ADAT at 8ch can't be beat, but AES3 over CAT LAN cabling is good also

skip XLR, use DB-25 to RJ45 / AES-72 for patch blocks, snakes

breakout cable matching RJ45-to-XLR or RJ45-to-DB25 adapter at the other end.

Proprietary AoIP gets expensive fast, with IT skillz stick to AES67, but IMO for recreational home systems above is just as good but MUCH easier.

A low powered PC or evenbRPi for routing and DSP. Besides RPi doing AES67, also have a look at the DSPi project here for ADAT and AES3.

USB for output from hosts, either a primary interface with the I/O format you want, or e.g. RME Digiface USB gives 4x inputs & outputs so 32ch total via ADAT connections to format converters in 8ch blocks.

Anything doing DA or AD should be BNC WC clocked, all DDC interfaces ideally as well.

Legacy secondhand gear can get down to $15-25 per channel.

These 8ch AD/DA converter boxen and primary interfaces are much more practical than one-way 2ch DACs, not least wrt clock sync'ing, phase drift smearing is a real issue especially full range, less so for subs LF

In my Chain no external Clocks needed or make anything better, i talked to RME and they told me thats don't do anything for me and is useless!!!

HDMI to AES (Processor or Extractor) --> RME HDSPe AES, 8x AES Out (up to 50dB Jita surpressoin) -->8x SMSL SU-2 AES in, XLR Out --> Relais Based Volumecontrol XLR in and Out --> HYPEX AMP's XLR in

I measured 3 DAC's at once and no drifts was showing with an scope after 30minutes of playing 1 kHz into it.

Also DAC's are synced because they get the Clock from RME Card thrue AES!

What splitter did you get? I tired an orei yesterday and it did not work, constant handshake issues with my mac

I also need to try an anti CEC adapter since that is also cause of issues of constant tv turning off

This. Orei

HX16-AES will be also an new Device and will play more than 48kHz on AES Out but comes out not realy soon, may be mid next year i guess.

The HX16-AVP will cost around 5k and will have Analogue in and Outs as well so not something i interested in and i hope the Price for the AES only version will be cheeper

So for me there is an Race between Hyperion DPR-16 (4 HDMI in) and NuprimeX HX16-AES (6 HDMI in)!

The Nuprime H16-AES was already outdated on lounch for me, because 48kHz only Device!!! For people that don't wannt more than 48kHz it is probably still the cheepest option for now.

Here the Information around:

Nuprime-Jason previously said the HX-16 will only decode Atmos at 48kHz, but indicated that it would "Allow for external hi-res stereo and multi-channel inputs"

The Nuprime H16-AES was already outdated on lounch for me, because 48kHz only Device!!!

Same as pretty much everything else, then.

 

[Frunse]

Ok i am Confused now and did an Question on that Forum, we will see! What he will answer.

He told anywhere in that Forum that the H16-AES was fixed to 48kHz on AES Out's, but that the HX16 Series will not and will become more expensive if i remember me right!!!

Really, there is NO objective reason to want higher than 48Hz

You're just Feeding the Beast talking about that here, like bragging about flushing money down the toilet

While there is some Atmos master material in existence at 24/96 there is currently no distribution channel that can deliver it, theoretically the DCP specification for cinema delivery supports it but in the real world there are enough issues with stuff not playing correctly that no one bothers.

If there was a mechanism to deliver AVR manufacturers might support it but they aren’t going to bother otherwise.

 

[john61ct]

My point is independent of whether the source material is delivered at higher sample rates or not.

When not - "even more" irrelevant?

No, always irrelevant.

 

[Frunse]

Nice, you can do what ever you wan't but i experiences already hires for long Time at 96kHz and it is possible to do so.

An AVR is capabel to play that and SACD digital to his internal DAC with high Samplerates not only at 48khz that was also possible at my Onkyo 5007 thru HDMI longer Time ago.

But not at Digital Out and thats because off Copy Protection Stuff and so on, The Industrie don't wan't to give it to you.

So i could throw all my Hires Media away and thats it LOOOOL
No, that would never happen

It's easey i skip ATMOS at all use my HDMI to 4xAES Extractor or buy me an Vanity Pro and can play all Audio hires like it should, Have only 7.2 Speaker Setup so anyway..... and i am already in haven LOOOOL

I am also able to add an cheep Nuprime H16-AES (1300€) only for Movies (ATMOS 48kHz) to an second bunch off 4 AES in on HDSPe Card (8 AES in's at all) build up 2 different Setups for CamilaDSP to switch between that 2 Bunch of AES ins and thats it LOOOL (with 2 HDSPe Cards even full 16 Channel in possible but useless for my Speaker 7.2 Setup)

Both of my Bluerays have 2 HDMI outs so all possible Also with an HDMI Switcher thats had 2 HDMI out possible to do so.

But H16-AES has still bugs makes pop's and noises like i read so i stay away for now, ATMOS i don't realy need often.

But in the future we get more and more Devices that's Capabel to do so and the Prices will go down.

Its already so cheep, in comparence to earlier days, to get an Softwarebased DSP with DAC's for up to 16 Channels or more with 192kHz
and the bigest Problem still are the Source Device that wan't give you the nativ multichannel digital Stream for all Channels and the Industrie wan'ts to sell the Hires Media ..........LOOOL

But an cheep DIY build HDMI to AES Extractor for 300 bugs do the job for now ..........but without native ATMOS Rendering. Probably not that bad Stil able to view my ATMOS Movies converted to LPCM.....

May be i am already Satisfied with my Extractor without buying anything else LOOOL....let see .....still Moving my Household to my new Apartment.....

So the Project willl need some Time......All parts bought......and don't forget it's an Hobby for me and i am not an normal Endconsumer for shure
So Time i don't cound here .....for my PCB design and CNC work as example

Sure it's youre opinion and don't help people thats on an different Route. I realy like that "48Hz"

It's an Hobby and Hobby's cost money loool

I could drive with an VW Polo to get from A to B but if i like to pay for an Ferrari to do the same route ......it's my choice!

Specialy on Americas Street with limited max. Speed

If i would be satisfied with 48kHz i could use an normal AVR for 2k with passive Speaker and thats it ....saving a lot off Money loooooooool

But where is the Hobbyfun than ......the experiences...... the developement on the System ......

Why people pay for an Turntable 10k or more knowing they have only 60 to 70dB Dynamic a lot off extra noises and wand to tell you its the Best way to listen Music lool

Where is the proove

It's like beliving in god without to accept all the biological experiences and Kowing we learned the last hunfreds of years And ignoring Darwin at all .......LOL

Ok its a bit off lol

 

[MCH]

I am holding all my efforts to see if the people of music assistant sort out wireless multichannel. As of now, they claim to have better latency than wisa for stereo.

 

[Frunse]

Of course some people would like it, KEF released his new Wireless Speaker:

https://valhalla-audio-shop.de/prod...3uz7zNJhG4T3z2cJ3ZkCWm3ELF0iEfzAaAsHoEALw_wcB

4k for an pair ........ and not my cup off tea The shape looks very good by the way only round eges

It seems to build for only Stereo, would be nice if it had an Dante input, LOOL on the Eathernet connection or ASE

I wish i could make an own Mould for an concrete or composite low resonance Material to build my own Skeaker with no edges around, but not with an coaxial Driver!

I have build my Speaker by my self as long i could think
Never bought an pair from an shop ready to play LOOOOL (Hobbytime)

While there's plenty of evidence that standard resolution audio is transparent, there's also plenty of evidence that it is not ( but that's probably beyond the scope of this thread ).

There is no objective reason to want higher than 48Hz - discuss

Apparently this is possibly wrong? Talking about recreational home listening, not creating, mix/mastering etc. I was hoping there was nearly a consensus on this here! Please chime in if you think it is true, no need for seeking out objective studies. But if you believe there are audible...

I would appreciate your views, and any links showing the latter

It's easey, i don't wan't to close the Hires Door in my Setup so i build it up with all the possebilitys we have today
So i decide to buy Devices able to do it this way easey, it is also most flexible!!!

At least my Crossover Filter on CamillaDSP will be the Limited Faktor, that may run at 48kHz or 96kHz or even more, like i wan't to do tests by my own!

96dB LR at 96kHz works well already but also able to go FIR 48dB LR @ 192kHz plenty off processing Power there!

So no limeted Faktors there on Hardware and i can believe my own ears or measuring equipments not only talking Peoples.
So i don't need to invest in new Hardware next year again and again and again.

I am open in Channel Count without degrading in possible Samplerate!
I am open in Samplerates
I am Open to Surround and Stereo Files
I am open for Streaming or Media playing (DAD, SACD, CD, Blueray, DVD)

Not wan't to close any off this doors at all!

Limiting Faktor, quality wise, would be always the Speaker or Room by sure And building Speaker is my main Hobby

Don't wan't to talk about +/- 1-2 % in Quality if the Speaker and Room does already more than 50% in Quality loool.

I decidet the SU-2 only because of Price Quality ratio and SINAD of 123,5 dB is already Clean as Hell and better than my Amps!

That why i don't like DAC's with Tubes or R2R they don't be clean there offten add Harmonics DAC's should never have an own soundstage like an Guitar Amp LOOOOL
It's not an Music Instrument.

Also the AMP's i chose because of the Price Quality Ratio, how many Amps for around 200-300€ are that clean with XLR in ?? (NC122MP.PDF):
And Flexible to use. The Only Channel i would look for an Class A or AB Amp would be the Tweeter, there you need only 1 to 5 Watt or so
But i like it already how it sounds with that HYPEX Amps.

But the Frequency Response off my Amps shows already (-1,5dB @ 50kHz 4Ohm, -6dB @ 70kHz and so on) there are no benefit possible higher than 96kHZ Sample Rate with it, so i stay with FIR 96dB @ 96kHz on CamillaDSP!

Thats my opinion
Every one is differend and has his own Targets and wishes also Budget

You need to toggle BB code in the signature editor (via 3 dot button at right hand end of the toolbar) then enter the BB code for the link directly. When you toggle BB code off again it will show as a link.

Thanks for your help. I tried lots of things, and I did get a hyperlink in the editor, but that never appeared in actual signatures.
