The eac3to normalize make impossible any clip, even if the decoder output have float values over 0dB the normalize function correct these values.

Does anyone know the command to extract a TrueHD stream from an Atmos stream? Excuse me if it's already been mentioned in this thread, I tried searching but couldn't find it and I don't want to sift through so many pages.

A little question : is eac3to a good choice to just demux a BD (2D or 3D) ? Thank you.

To mainly obtain the audio streams: Yes. But it won't care much about all other streams, I believe...

Atmos or not you can extract the standard TrueHD (without Atmos info) with:

eac3to stream.thd+ac3 stream.thd

if the stream is already extracted, or from the BD, if TrueHD is track 3:

eac3to movie.mpls 3: stream.thd

Yes for 2D BD, I'm never try a 3D if you want recover 3D info (3D planes for 3D sups, etc.)

I use eac3to for de-multiplexing audio and video streams from BDs on a regular basis. I'm surely not alone.

^ OK, practical experience.

I can't understand how eac3to show a duration of 0:06:29 when seems (by size, channels, bitdepth and samplerate) the correct duration is 00:22:09.205 like show MediaInfo.
Thanks for your observations. Regarding the differing durations, please note the info I posted was for two different tracks in the same set (album).

I'll clean up that info for consistency, and post the wav when I get back tomorrow night. The sample is actually about 1.6gb, but I also put a 176 eac3to down sample log that shows the command line, and a pic of the static I get.

Perhaps in this case, the issue is related both to the embedded artwork and expanding to 32bit to apply gain.

Just to reiterate that sox approach worked without issue.

And I'll post some additional info as described in my previous post related to a 352-176 down sample issue I had with eac3to. The hotel wifi never lets me upload something that big.

Thank you ! BD 3D info is not a problem, I can extract it from MPLS file. I will try if MVC file extracted keeps 3D planes info.

I'm trying something like this but I'm still getting an outputted Atmos track:

eac3to.exe "source.mkv" 2:aud2.thd

No for the subtitles of most 3D BDs. If the same subtitles are present in the AVC M2TS and in the MVC M2TS (and it's frequent), eac3to fails completely, and you have to unselect the subtitle streams and retry. AFAIK, for everything else, eac3to works fine as a demuxer.

@canuckerfan

What is the problem?
The <WARNING> is related to 24 fps, but the "aud2.thd" seems extracted fine.

@junior_l3oss

When your command line don't work can be:

1) eac3to don't support this kind of eac3

2) Or the eac3 stream is buggy because:

2-1) A bad capture of video from Netflix

2-2) Or a bad stream extraction from video

We can't know the problem without a sample of your video.

Seems the creator of this program 'madshi' "doesn't have the resources" for this insanely difficult problem I face....which is ridiculous.

90 google results pretty much end up in this question never getting answered. 3 times it has been asked here and never answered..but here goes yet again.

I have Nero 7 installed and I have the HD/BluRay plugin installed and registered yet EAC3TO still seems to crap on me. It keeps saying cannot find Nero Audio Decoder 2..which is BS.

eac3to.exe -test
eac3to (v3.31) is up to date
Nero Audio Decoder (Nero 6 or older) doesn't seem to be installed
http://www.nero.com/eng/store-blu-ray.html
CAUTION: You need Nero 7. Nero 8 won't work with eac3to. (errr wrong Nero 7.8.5.0 ..its installed and registered ALONG with the BLURAY plugin!!)
ArcSoft DTS Decoder doesn't seem to be installed
http://www.arcsoft.com/products/totalmediatheatre
Sonic Audio Decoder (3.31.0.0) doesn't seem to be installed
Haali Matroska Muxer (2013-04-14) is installed
Nero AAC Encoder (1.5.4.0) is installed
Surcode DTS Encoder (1.0.29.0) is installed



TL;DR

I think program is dead when trying to do AAC to AAC/M4A
