Cavernize free EAC3 Atmos decoder - Page 2

Balling · 30th January 2023, 06:45

My idea fixed "for older than 22H2 OS", it was unrelated DWORD allignment and now all decodings must work. That also removed the need for 10 extra channels for compatible Atmos and now 24 bit is the default not only for ADM, but for renders too.

This works very good.
I will donate.
I have noticed that some objects get distorted or have artifacts at some points.
But most of them seem properly decoded.

We are aware.

Does anyone know the maximum number of ceiling channels supported by E-AC3+JOC (aka Dolby Digital Plus Atmos)?

Also, since there is a FOSS implementation now, and it may be used in free-to-air broadcasts someday, do we have a patent list?

Theoretically infinite amount, because it is dense subset of R. In practice the coordinate decimal is like 6 digits and has higher precision in TrueHD. 24.1.10 is what is supported max in practise, so 10 Top channels. Note that Bottom channels are also possible, and that the Eye of god (perfect overhead) is probably impossible.

The number of supported ceiling channels is the same as with Dolby TrueHD.

However, for use within the home no more than six channels are created/mixed, which can be folded down to 4 or 2, depending on the capability of the Atmos decoder.

What do you mean by "R"?

Greetings to the forum participants.
I need your help.
I'm trying to get Dolby Atmos audio from the HDMI port, but I can't figure out how to properly decode the data into 7.1.4 format
Can you explain to me how to extract the necessary data from a bit stream and arrange it into channels?

What is the current status of thd+atmos to eac3+atmos conversion?

Any tutorial available?

tebasuna51 · 3rd November 2024, 17:23

Cavernize is a free EAC3 Atmos decoder:

- Can't decode thd+atmos
- Can't encode eac3+atmos

Then can't be used to convert thd+atmos to eac3+atmos.
To do it you need commercial Dolby software.

Even a tutorial for commercial software would be more than welcome.

I saw some "eac3+atmos" conversions around and I am curious to know how to.
