eac3to - audio conversion tool

[nurbs]

Works like Nero. You need a "-" (without the quotation marks) where you normally put the input file and most likely also "-ignorelength".

simple question please: I get a checksum error on the BD of "The Nightmare Before Xmas":

M2TS, 1 video track, 6 audio tracks, 17 subtitle tracks, 1:16:38, 24p /1.001
1: VC-1, 1080p24 /1.001 (16:9)
2: TrueHD/AC3, 7.1 channels, 48kHz
   (embedded: AC3, 5.1 channels, 640kbps, 48kHz)

Anything I can do

[starmanj]

Is there a tool to automate MLP creation using Surcode with eac3to? Like the old Wavewizard did for DTS files?

Is only a WARNING, the flac is OK?

[lostclusters]

I have been attempting to back my BluRay LotR EE discs. My Flac encoded audio is distorted and out of sync. I have not had this trouble with any of my other discs. I use EAC3TO and HdBrStreamExtractor as a gui. I have the TMT codecs loaded and my log show them being used. Has anyone else seen this issue and what can be done about it?

[tebasuna51]

There are two problems with DTS-MA 6.1 (like included in BluRay LotR EE discs).

- You need ArcSoft Decoder v1.1.0.0, other like v1.1.0.7 make wrong 6.1 decodes.

- If you downmix DTS-MA 6.1 to 5.1 with eac3to the surround channeles are wrong mixed.

What's the best way to ensure the correct version of that codec? When the discs are played (w/TMT3) they play fine.

piranha (REAL 3D + 2D)

I created the iso using anydvd HD, then using clownBD I'm trying to backup the 2D form

There are two tracks

1) 00005.mpls, 00007.m2ts, 1:28:20
- Chapters, 12 chapters
- h264/AVC, 1080p24 /1.001 (16:9)
- DTS Master Audio, Italian, multi-channel, 48kHz
- DTS Master Audio, English, multi-channel, 48kHz

2) 00004.mpls, 00005.m2ts, 1:28:20
- Chapters, 12 chapters
- h264/AVC (left eye), 1080p24 /1.001 (16:9)
- h264/AVC (right eye), 1080p24 /1.001 (16:9)
- DTS Master Audio, Italian, multi-channel, 48kHz
- DTS Master Audio, English, multi-channel, 48kHz


so I selected the 00004.mpls and then the left eye stream with DTS Master Audio, Italian and italian subtitles
eac3to is logging plenty of "The source file seems to be damaged - discontinuity" and cannot demux
It doesn't seem a bad rip because I can demux 00005.mpls without any errors.
Any ideas?

hi..
edit:the first question was stupid.. there is a specific function for delay without using edit...
And a second question.. is there a way to do multiple edits? it's boring to have to create 4 files to do 4 edits..

Thanks!
I was wondering why my ripped LotR EE mkvs had this horrible sound. It's working perfectly now.

1) Yes, include only the delay: -640ms or +640ms
2) No, sorry.

How do I get the version number from the codec?

Open Windows Explorer, right-click on the file dtsdecoderdll.dll, select "Properties".

Tyvm!

[robpdotcom]

Which version of TMT included v1.1.0.0?

since this is exactly what I want do do ( 6.1 DTS-MA -> 5.1 Flac ), could you please give me a hint what's going wrong when downmixing with eac3to and version 1.1.0.0 of the dll ? My idea to circumvent the problem would be to decode the 6.1 DTS-MA to 7 seperate wave-files, to do the downmix to 5.1 manually in a correct way using audacity and then to reencode the wavs to a 5.1 Flac.

Thx in advance, Nanobot

In this thread: http://forum.doom9.org/showthread.ph...10#post1465610

Now eac3to make the downmix 6.1 -> 5.1 with:
SurroundL = Cs + 0.7071xRs
SurroundR = Ls + 0.7071xRs

And must be:
SurroundL = Ls + 0.7071xCs
SurroundR = Rs + 0.7071xCs

Yes, you can decode the 6.1 like wav's and make the mux manually.

[NanoBot]

Hi,

for the link and the information, that is accurately the info I was looking for.

Nevertheless, I would suspect that this downmix matrix for the surround channels might result in levels above 0dB for Ls and Rs ? Or are the levels for Ls, Cs and Rs in a 6.1 DTS-MA file are already limited to values where Ls + 0.7071 x Cs and Rs + 0.7071 x Cs can't exeed a level of 0dB ?

If my concern is true, would it be ok just to normalize those two channels after the downmix, or do you have a recommendation how to avoid this probable problem ?

C.U. Nanobot

[tebasuna51]

Yes, we always need normalize after a downmix.
eac3to normalize the 6 channels automatically.

[musinsky]

Hi,
is there any way to set "not standard" stretch ?!
For example, how with eac3to make stretch 25.002 -> 23.976 ?

Thanks.
