Wav file display text change! Is this possible?

[wolflop]

Hello,
something extraordinary. Would like to change the display in the AVR with a film sound pcm / wav file. This means that DD + Surround is displayed. How can I change that in the original wav file? B is then displayed on the receiver Surround? Is that possible?

Would be grateful for professional information

If I understand correctly it is not possible.

You can recode the PCM/WAV to DD+ and replace the track in the film, but if the track is a PCM/WAV the AVR can't show DD+

[wolflop]

but my denon 7200WA shows on the display dd+ surround. Its a atmos wav file... so would change the name in the display to atmos.... I think that maybe you can write something in the text code in the wav file .. just Atmos ... so that the receiver shows it ... No idea!

How many channels is your WAV file, and how did you make it?

[SeeMoreDigital]

For anyone who has an Apple TV 4K device connected to their AVR's, it's worth noting that it does not pass DD+ audio (with or without Atmos) as a conventional bit-stream.

It uses an audio packed transport system known as Dolby MAT (Metadata-Enhanced Audio Transport). Which transcodes 'variable bit-rate Dolby bit-streams for transmission over fixed/constant bit-rate HDMI connections within a PCM stream'.

Cheers

1- What is the channel layout in Resolve? 5.1.2/7.1/other?
2- Are the 8 objects still, or moving?
3- What settings did you use when saving from Resolve? Mind sending a picture of your audio workspace in Resolve?
4- Are you on windows or mac?
5- What audio encoding software do you have? FFMPEG/Dolby Atmos production suite/Totalcode/other?
6- Does the WAV file play back correctly on your denon 7200WA AVR?
7- What speaker layout is on your AVR ? 5.1.2/7.1/other?

[wolflop]

1. channel layout 7.1.4
2. still
3. Attachment
4. Win10
5. only resolve
6. viewed pearl harbor audio sounds correct.
7.speaker layout 11.1 and 10.1

Are you able to provide a short sample encode?

Sorry, File deleted. File size was 12 GB.

[junh1024]

What are you trying to do in Resolve? Turning 7.1 into Atmos somehow? You can already turn 71 into Atmos by enabling upmixing: DSU or DTS NX on your AVR.

[wolflop]

my goal was an Atmos audio file. This file was created with the Resolve or Dolby Conversations tool as atmos. wav generated. But it is displayed in the AVR as DD + surround. But there is also a tab for auro3d in resolve. But I don't know how it works. Or then DTS: X you would only need a DTS master suite

[junh1024]

Resolve doesn't include any Dolby, Auro, or DTS encoder, and making a genuine Atmos/Auro3D/DTSX mix requires more than just 71 input (https://i0.wp.com/www.evanschiff.com/bd/wp-content/uploads/S2S_After-1024x272.jpg) (example of 51 mixing), and many hours. Encoders are separate products.

Anyway, you can convert 71 PCM to 71 DDP using Totalcode studio, or similar software, and then upmix to Atmos using DSU on your AVR.

(See also Tebasuna's reply)

If you want free 71, you can encode to AAC using FFMPEG, qaac, etc.

[wolflop]

You may all be right; I am still too little in the matter for that.
'Actually, I just wanted to know how to rename a wav as a track name' and not fire up a discussion about whether the file can be created or not. Apparently that doesn't work with pcm wav.
That's why I took the DTS: X track. For the DTS: X variant mentioned above, this is displayed on my AVR (Attachment)
I don't need to change anything. It's the better sound variant anyway ... than Atmos
Maybe only my receiver is defective.

[junh1024]

A Few things:

1- You can't change the display text, since your AVR displays what it detects
2- Your AVR can't detect Atmos WAV/ADM, since ADM is a mastering/editing format, not meant to be played by consumer AVRs.

To the AVR, it's just regular WAV, and that's what's displayed.

Ok, the didplayed Audio is Not a wave. Ist an dtshd audio

ED: nvm

PCM doesn't have any kind of metadata.
In real life scenarios you generally start from a DAMF package (Dolby Atmos Media File) in which there are three files: a real audio file with the beds, a channel layout file and a metadata file for the objects. Then you take something like an official Dolby Encoder or third party products like Emotion from SDVI (although I'm still talking with them about this so I'm not sure they can actually do it) to create a Dolby ED2 Atmos stream which uses two audio pairs in an MXF and there are two 16bit PCM multichannel 5.1.4 essences spoofed as two stereo PCM 24bit tracks. That's the only way you can carry Dolby Atmos through SDI for instance. Then you need a Dolby decoder at the end to detect the flag and decode accordingly. That stream is then generally re-encoded live by live encoders in something like E-AC3 for consumers.

That being said, what you wanted to do is not possible...
If you want Atmos to be carried over as PCM you need Dolby ED2 and that requires proprietary Dolby encoders or third party products that pay few hundred bucks to Dolby...
None of them is included in free open source software nor Davinci...

[wolflop]

ok, of course you are all right.

You're better off using imgur as using attachments requires the approval of moderators and can take time.
Anyway, this is an extract of a presentation I made long time ago and it's what I meant and it's what it's generally done professionally (at least from a broadcast point of view):
