Very interesting, but in your link:
"Purchase a license for the Dolby Media Encoder ($400 /yr). The Dolby Media Encoder comes with the Dolby Reference Player. The Dolby Reference Player is the app that's needed" Maybe if free soft can do the same.

Yes, the Dolby software is needed at present. But it's a one time purchase. "Subscribing" yearly is optional.
$400 is fine by me. Compare that to the cost of a competent AVP or AVR. But of course, if any free soft can do the same, great! That's why I posted here... |

There are a free soft Cavernize
But the method suggested here with the Dolby Reference Player don't work for me: Quote:
If only can output 2D sound, like can do ffmpeg, is usseless for me. Do you know a way to obtain at least a --out-ch-config 5.1.2 (3D) at least?

Yes.
There are other thread to speak about Cavernize, I only answer to chandersson question: "But of course, if any free soft can do the same, great!" Here I say than drp.exe (Dolby Reference Player command line decoder) can't output 3D audio, only 2D 2.0, 3.1, 5.1, 7.1, like can do ffmpeg, then it is useless for Atmos decode to 5.1.2 than I need to recode to EAC3 (L R C LFE Ls Rs Vhl Vhr). I don't know how can output audio files with the GUI asociated to DRP. If you know how do it please explain me.

Okay, I will rephrase that. "Are you serious? You need to use GUI." See? It was not a question. To get object extraction you need to use CavernGUI to ADM. To get render you need to use PCM, not ADM PCM, and that will allow to select what render do you want.

Golf clap to all the people out there uploading Atmos-only MKV files without an AC3 of AAC-LC compatibility stream... they are the reason Atmos decoders for PCs and SmartTVs are even needed, and they are instrumental in helping Dolby set up a toll-booth for everyone wanting to make an MKV player, filling Dolby's coffers in the process. They are the same people who filled DTS Inc's pockets with their DTS-only MKV files. And yes, I know that a decoder for Atmos exists in ffmpeg, but it can't be distributed everywhere due to patent issues.
Save for those Atmos-only MKV files, nobody should really need a Atmos decoder: Streaming services will only serve it if your setup supports it, and Blu-Ray discs must contain an AC3 compatibility track that non-Atmos users can decode. In plain English, with the exception of those MKV files, Atmos is something that's meant to be bitstreamed to a relevant home cinema system, not decoded. PS: I hate those H.264 MKV files with the fire of a thousand suns. The only real-world reason they exist is to sidestep the MP4 requirement for an AAC-LC compatibility track. A requirement which is there to make MP4 files universally compatible. Even if a player "supports" MKV, there is no guarantee it can play a particular file, and those Atmos-only MKV files are the real-world proof for it. Sorry for the mini-rant, but I wanted to get this out of my system. Last edited by kurkosdr; 22nd September 2022 at 02:33. |

I found a way to record the sound played by the Dolby Reference Player GUI.
- With an AVR conected by HDMI to PC, a audio editor, the free Audacity can work, configure the Host like WASAPI and the Recorder Device to the AVR (loopback). See first image. - Open the GUI and configure it like the image 2, for a (image 3) output configuration L R C LFE Ls Rs Ltf Rtf or the desired, load the Atmos and Play - In Audacity record the sound (maby you need stop and replay in the GUI to record fine the begining). I finish with a wav 7.1 24 bits (the last 2 channels are the TFL and TFR) PROBLEM: the decoded time is the same than the duration. But at least can be used to compare to Cavernize or other Atmos decoder.

@tebasuna51:
a (maybe stupid) question: is it possible to play any Atmos track (TrueHD or E-AC3) simply using whatever player (MPC, VLC etc) and Dolby Atmos for home theater (thanks to Dolby Access), and then record it via Audacity as you have written in your previous post? |

@spoRv
I can't/wan't install Dolby Access in my PC's. I don't know if MPC/VLC can use the installed filters. It is also a not free solution with the same problem (record time). You can try and inform here.

Dolby Access does not decode Atmos, LOL. What? It sends it to a decoder in TV or AVR. And if you are talking about Headphones... Well, that is binuaral, i.e. just stereo. It does decode Atmos but just to stereo. Last edited by Balling; 26th September 2022 at 04:48. |

Why are you using any AVR? Just use ASIO or VAC. BTW, can you compare this fix, please: https://github.com/VoidXH/Cavern/issues/14

With other options I obtain only 2.0 But you can try other methods of course. Quote:
With Cavernize we can define the speakers position (good option) but not with DRP, maybe the Cavernize default position is different than DRP and the mix matrix between ADM and the wav 5.1.2 (for me) is also different.

I'm late to the party but I do have a question.
So, I'm currently on Fedora 36 x64 and I can't play E-AC3 streams. To test this, I went to this reference player suggested by Derek (Blue_Misfit): Link, I pasted the following stream https://dash.akamaized.net/dash264/T...48_768_ddp.mpd and I clicked "Load". Needless to say, it was completely silent both on Chrome 106 and in Firefox 104. I'm running Fedora 36 x64, the audio backend is Pipewire/Wireplumber, I have gstreamer1-plugin-libav-1.20.3-5.fc36.x86_64, gstreamer1-plugins-bad-free-1.20.3-1.fc36.x86_64, gstreamer1-plugins-bad-free-extras-1.20.3-1.fc36.x86_64, gstreamer1-plugins-bad-freeworld-1:1.20.3-1.fc36.x86_64, gstreamer1-plugins-good-1.20.3-1.fc36.x86_64, gstreamer1-plugins-ugly-1:1.20.3-1.fc36.x86_64 as well as ffmpeg-libs-5.0.1-3.fc36.x86_64 installed. and yet... nothing. Is there anything I can do to play E-AC3 streams on Linux (Fedora)? I also tried with Chrome 106 on Android 13 (Google Pixel 6 Pro) and it's just as mute as it is on Linux... For what it takes, I also tried on Windows XP x86 with Microsoft Updates 'till 2019 with Chromium 92 (July 2021) and K-Lite Codec Pack 13.8.4 Mega (May 2018) and of course it's just as mute as the other two... The funny thing is that if I open the mpd stream with VLC I can totally decode it, which means that there is a decoder available for Linux, it's just not being used by Chrome nor Firefox... Recap: OS: Windows 98SE x86 Browser: Retrozilla 2 Codec installed: K-Lite Codec Pack Full 2.69 Result: Mute OS: Windows XP Professional x86 Browser: Chrome 92, Palemoon 28 Codec installed: K-Lite Codec Pack Mega 13.8.4 Result: Mute OS: Fedora 36 (Linux) x64 Browser: Chrome 106, Firefox 104 Codec installed: libav 1.20.3-5 Result: Mute OS: Android 13 Browser: Chrome 106 Codec installed: default Result: Mute OS: Windows 10 Enterprise x64 Browser: Chrome 108, Firefox 106 Codec installed: K-Lite Codec Pack Mega 17.0.5 Result: Mute Browser: Microsoft Edge 105 Result: Normal Playback Last edited by FranceBB; 27th September 2022 at 11:00. |
