I’ve never seen anything like this! Why on earth is it so difficult to get an ATMOS mix out of the studio? This is supposed to be the easy part! Do the mix then PRINT IT!
How are you guys able to test your work before shipping it out to your clients?
Most ASIO drivers have been multi-cluent for several years.
So, what’s the file format printed on Blu-Ray disks?
If you have an MP4 file, then you still need to “treat” it appropriately so that it can be read by a Blu-ray player. You can also play it as MP4 file with many players (for example via USB stick). But if you want to simulate a “real” Blu-ray, or your player doesn’t play Atmos via USB, then you have to convert your file.
We quickly push our tracks into Scenarist for testing. But we also author (UHD) Blu-rays, so we have the software available here anyway. 
Alternatively, DME or DEE owners can of course use the Reference Player to test their own mixes. However, if you want to get a real impression of how your mix will sound to the end customer, you need to play it back the way our customers do (Blu-ray, UHD-BD, Dolby Access, etc.).
It gets really funny when you know that many customers only listen to Atmos through a soundbar. Or when you know that there are many settings in the AV receiver that have a big impact on the sound of an Atmos track. 
I would like to add the Dolby Encoding Engine (DEE).
However, the DEE is only for gourmets as it is all command line driven. The DEE is extremely customisable and can, for example, also be used for video (Dolby Vision).
If you don’t want to buy your own software, these online providers are worth considering:
Note: Most providers only support Atmos in conjunction with Dolby Digital Plus (E-AC-3 JOC).
Thanks so much for this tip. I’ll take all the help I can get on this. Unfortunately, IT DIDN’T WORK. 
I loaded the MP4 into tsMuxer and created the .iso file. I wrote that to a blank DVD disk (does this make a difference? Should it be a dedicated Blu-ray blank disk?) and popped it in my Blu-ray player, only to get the same error message.
Note: There is NO VIDEO on my export. IT IS AUDIO ONLY. Does that make a difference? My Blu-ray plays CDs, DVD’s, Blu-rays and, so far the 3 ATMOS/DTS labeled commercial disks of “Dune,” “Tar,” and Bob James’ “Feel Like Makin’ Live.”
I’m not particularly interested in wasting money burning “Coasters.” So, if there is ANY other viable option to get the mix out of my studio and make it playable on my home theater system, I would appreciate those instructions as well. I’ve tried several ways to get the files to play through my new HP laptop (Win 11 Pro/2TB ssd/64Gb Ram). The included Windows Sonic Immersive player wouldn’t see it. I downloaded VLC, which suppsedly includes ATMOS, will see it and appears to be playing it. But I can’t tell because there’s NO SOUND. I tried running the audio out through my HDMI port into the home theater system via pc connect as well as chrome casting. NONE of those methods yielded any results, let alone positive results!
The Post Guys over on the Avid site said that I need an APPLE DEVICE to play the file. I’m a 100% PC/Android guy! So the ONLY Apple device I own is an old 10" iPad I bought used a few years ago to prepare for an S1 purchase, that never happened (I got Nuage instead). How would I even be able to get he file INTO an iPad?
Meanwhile , I have tried to download the Dolby Reference Player Software. But I’m hitting walls there too saying : This professional software is available for users who have purchased or have requested and been approved to receive an evaluation for the following professional software products only:
Dolby Encoding Engine with Dolby AC-4
Dolby Media Encoder with Dolby AC-4
This is from 2021. So, I don’t know how valid this is now. But it’s NOT showing any links to actually download or links to purchase a download. So, right now, that’s another dead end.
This is madness and Elliot Scheiner is absolutely right! This GATE KEEPING SCHEME IS TOTAL BS!!! 
No, you can also burn the BDMV folder structure onto a blank DVD. The media doesn’t matter as long as the player can read it. (And, of course, the capacity of the blank DVD is sufficient. )
Only audio will not work with the BDMV folder structure (Blu-ray). Video is essential. (May be a still/black image.)
The Reference Player is linked to the purchase of the products you mention.
As I have lost track of things, what file format or codec is your Atmos mix available in?
If you would like to entrust me with your audio track, I can create a compatible ISO image for you to burn onto a blank disc that your Blu-ray player can read 100%. Just drop me a line.
That is not true. 
As long as your laptop/computer is connected via HDMI to an Atmos-enabled AV receiver or AV amplifier, you can play Atmos with any software player. All the player needs to do is provide a bitstream audio output. (PowerDVD, for example. But the free MPC-HC can also output Atmos as bitstream with the right settings.)
Provided, of course, that a home cinema track is available: TrueHD with Atmos or E-AC-3 JOC. Atmos master files (ADM BWF, etc.) will not work!
Well, that sounds like the “missing link” right there. So, how do I do that? ADM Export won’t includ a video file, right?
No.
But it would not matter in your case. Because it is a master file, you cannot play it with a home cinema component. No matter if Dolby Reference Player, PowerDVD, MCP-HC or a self-burned Blu-ray in your Blu-ray player: You need a consumer track (TrueHD with Atmos, E-AC-3 JOC or AC-4). You can only playback a master file in Nuendo or using the external Dolby renderer. But not with a Blu-ray player, the Reference Player or a software player.
Without a track in one of the above formats, you will not get anywhere. If you have an E-AC-3 JOC track or TrueHD with Atmos track, you can only put the Atmos track into an MKV container and play it directly with MCP-HC. You don’t even need a video file. But it must be a home theatre track, otherwise it will not work!
I never meant to try to play the Master File. I was just saying that my master file was Audio Only. I’m asking how to get the video added to resulting MP4 file I made, since it would not be possible to export the ADM & Video from Nuendo.
If I render the video file in Nuendo how would I combine it with my ADM to make a single file to convert into MP4 and then the ISO print?
Dolby Atmos Renderer (was DAPS) will export an MP4 with video.
But HOW do I marry the video with the ADM?
For a second, I THOUGHT I had a workable solution. I opened a session in DaVinci Resolve and added my co. logo as a video file and then imported my MP4 print of the file. Unfortunately as I only have the free version, it would not accept the multi-track version and turned my audio into a stereo track. Only the paid version supports ATMOS.
So, I need to figure out how to render the video file WITH the ADM in Nuendo and then convert that.
Why do you want to combine the master file (ADM BWF) with the video? I don’t get it! 
(Note: If you export only a certain range, make sure it is identical for both exports.)
Now you can play this file with MPC-HC.
If MPC-HC is configured correctly, your AV receiver/AV amplifier will play Dolby Atmos.
Look at your own steps:
That’s combining audio and video. I don’t think it was necessarily clear that the audio to be added to video could not be an ADM file. That’s probably what was confusing.
I don’t. You said that the Blu-ray player wouldn’t play my AUDIO ONLY MP4 file. So, I was trying to figure out how to put them both together into a file that the Blu-ray would see and playback.
This page is riddled with confusing ads! Every link I tried to download the actual app was having me download something altogether unrelated.
But I thought that was clear. Not only is it the conclusion of the whole thread up to this point, but I mentioned it several times. @Keyplayer even quoted the paragraph where I wrote it again.
You can’t play a master file on home cinema equipment. You can’t. You have to convert it to a consumer track. (This also happens with the MP4 export using the external Dolby renderer: It exports the Atmos mix as an E-AC-3 JOC.)
Just to be on the safe side: What kind of audio track (the codec) does this MP4 file contain? (If you like, you can use the free MediaInfo and post the result as text.)
This is the link for the Windows (x64) version.
