Atmos finally decoded in PC/Mac

[VoidX]

Since other Korean users were getting interested in your software’s VB-Cable–based Atmos playback, I decided to give it a quick try too. If I used Atmos more often, I could have tested more things, but I don’t, so the info I provided is just from my own playback attempts—and as I mentioned before, I’m not very familiar with players. So the MPC-HC issue was probably my mistake as well. I’m sorry I couldn’t be of much help!

You helped a lot with showing the improvements in JRiver and support from PotPlayer. MPC-HC seems the same to me, it cannot play anything over 8 channels, not even just the file on a system with fewer channels.

When rendering some Atmos files to 7.1.4 wav(PCM, integer), I get the following error.
This file had some parts which were coded in sparse JOC. This part of the E-AC-3 standard is not correctly documented, thus can't be decoded, and was muted. Small distortions in the audio are expected.
Do you know the solution?

There is no solution, it's misdocumented by Dolby. Most of the time the file is perfectly fine, I just had to add this to prevent error reports, because some demos (like Amaze) click because of sparse JOC.

The combination of VBCable 16ch and Cavern, working without the need for additional AVR or interfaces, is quite interesting.
@VoidX nice job. thank you

Hello, where can I see the tutorial, thank you

Huge news, Cavern gets TrueHD Atmos support by 15th August.

I am going to read this thread later and I wonder how I can get my Dolby Atmos sources into a windows pc to use Cavern. May I ask for some advice on this?

For example, I buy all my movies on the Apple TV app.

I'd prefer to use a pc as a surround processor rather than forking out on what's available in the AV processor market.

Intriguing. Is that just for music, or is it for movies as well?

I think a lot of people have been hoping for this for a long time.

DRP?

DRP?

Disaster Recovery Plan? Digital Risk Protection?
If you want people to read your post the least you can do is type out the acronym.

The other piece of software to decode Atmos (MMH) is based on the Dolby Reference Player. I am curious if this update to Cavern will not need DRP, and make it even easier for people to jump into the Atmos game.

Both.

DRP?

No. It will be completely free.

 

[welwynnick]

Both.

Fantastic!
I was beginning to think it was Blu-ray audio only.
Will it also work with 4k Blu-rays? They seem to be a bit more of a problem?

All TrueHD tracks adhere to the same structure, there should be no difference.

Thanks. I get that, but to the best of my knowledge playing UHD Blu-rays on a PC got difficult recently. No reflection on Cavern.

I either need an old CPU that supports SGX, or I need to rip the disc, plus I need legacy software and firmware.

If I wanted to play a 1080p video Blu-ray with Atmos, and decode using Cavern, how would I play the disc? PowerDVD? VLC?

Does it have to be ripped first?

Cheers, Nick

Yes, it's currently a converter. Real time version has no release date, but it's in the works.

Got it.
It just keeps getting better.

I am looking forward to the real time version.......

 

[welwynnick]

To be clear, will that be a Dolby TrueHD Atmos real time converter, rather than Dolby Digital Plus?
DTS-X?

Yes, it will decode soon, and will be real time later. No DTS:X documentation or reverse engineering is yet known, so that's not planned at all.
