You are right seems only work with integer values.

It does work with -no2ndpass, but then it has some, albeit minor, clipping.

Don't worry with the clipping, they are always encoder/decoder imperfections, the original source can't have peaks over 0dB.

Recode from lossy formats never can be exact.

Eac3to is due for a refresh...........................................

The Nero decoder doesn't seem to work, will use libav instead...

Do you have tried to use nero ac3 decoder??? Apparently, it isnt installed.

Madashi has stated that once MadVR reaches v1.0 work on eac3to will continue.

No. IIRC you needed a fairly old version of Nero for this, and I have a newer version installed which I needed for some new features (I forget what exactly).

Looks like DRC isnt disabled properly

Better use libav..works without Problems. And i dont think you hear big a Quality Difference generally between Nero and libavcodec on AC3/EAC3

AC hasn't been around for some time now.

Does anyone know if the above applies to both DD and True-HD ?

Anybody ??

Overdrive80 · 25th July 2012, 20:19

If eac3to doesnt remove DRC properly and I dont want use libavcodec. What could it be other option??? Maybe Audition??

ramicio · 26th July 2012, 18:26

How doesn't it remove DRC properly? It's just a gain metadata. Why don't you want to use libavcodec? Why would one want to go from AC3 to FLAC?

rapscallion · 26th July 2012, 18:44

@ramico, see my post above re the same, #11708.

ramicio · 26th July 2012, 18:45

What?

rapscallion · 26th July 2012, 18:46

What do you mean "what"? Did you read the post and the links.

ramicio · 26th July 2012, 18:49

First off, my first post wasn't even replying to you, it was to Overdrive80. Secondly, I read it, and I don't see what it has to do with anything I said. The problem is not with eac3to, it's with a codec. I was asking Overdrive80 what was wrong with libavcodec, because it will function perfectly.

rapscallion · 26th July 2012, 20:15

Whoa, slow down ther ramico.

I know you weren't replying to me, but Overdive's question was in response to my post, right above his.
You commented re DRC and metadata so my post has everything to do with what you said. I was hoping you could clarify things for him and me.

My post(s), I asked this back on the 15th as well (w/no responses): http://forum.doom9.org/showpost.php?...ostcount=11699 referenced the Nero codec, which ACrowley stated removal of drc was a problem.

We are here to help each other, no ?

Overdrive80 · 27th July 2012, 00:52

Ramicio, I havent any reason for not use libavcodec. My question is mainly based on the curiosity to know if there are alternatives.

my question is a consequence of assertion of rapscallion. Is there technical data for it??? I actually use nero for disable drc on my projects, and it worry me.

Thanks

ramicio · 27th July 2012, 16:37

Why not just use libavcodec, which comes with eac3to, instead of a third party codec that doesn't even work?

From the first post in this thread:

So, it has always seemed safer to me ( and Overdreive) to use Nero. Until, of course, the drc question. Do you know if the "problem" applies to both DD and TrueHD ?

ramicio · 27th July 2012, 17:14

It shouldn't apply to TrueHD. It's really MLP in disguise, and is lossless. Specs weren't hidden for it. EVERY different lossy decoder will give a different decoded result. This is the nature of all of this psychoacoustic lossy pseudoscientific pseudomathematic BS. Want consistency? Go lossless.

Thanks for the info...that is what I was hoping !

Always go lossless. However, and just my personal prefrence, I use eac3to to create the wavs from a BD TrueHD track and then use DTS MA Suite to create a DTS-HD track to mux back with the original video.

Thus, my reason for asking.

ramicio · 27th July 2012, 17:21

Why the love for DTS-HD?

rapscallion · 27th July 2012, 17:23

Well, and this has certainly been a matter of discussion on the boards, I'm not a fan of DRC.
