eac3to - audio conversion tool

eac3to main.ts main.aac

Track 1 is used for destination file "main.aac".
a01 Extracting audio track number 1...
a01 Creating file "main.aac"...
eac3to processing took 1 minute, 52 seconds.
Done.

It's a file recorded from TV broadcasting with HEVC Main10 video stream and AAC audio stream. It has about -450ms delay, and since eac3to can't recognize the video, it cannot figure out the actually delay.

I believe it only happens when a TS file is given, as with MKV it seems to work fine.

Hey again guys,

I demuxed a TrueHD stream from a BD, and eac3to reported a delay of 125ms in relation to the video stream.

That means the 125ms audio delay is originally included in the BD, correct? I assume I don't need to "fix" the delay when muxing into an. mkv, because that's how it got out of the studio.

Am I right? Thanks in advance!

You need fix the delay because eac3to can't apply the delay over a TrueHD, like do automatically with other audio track.

Thanks for the reply @tebasuna51. How do I proceed about applying the delay? Do I just do it via eac3to? Thank you.

[tebasuna51]

eac3to can't apply delay to a thd.

When add the .thd in MkvToolNix GUI, select the track and put the Delay (125).

[gzuz]

Thanks man. I actually thought I have to apply a negative delay. But I realized it's a positive delay when I muxed the files. :D

Thanks again for the help, it's appreciated!

Is the -shutdown parameter confirmed as not working? It has never worked for me (Win 8/10, admin account).

[NanoBot]

Hi,

i just learned that FLAC has recently been updated to version 1.3.2. Does anyone already has compiled a new libflac.dll ( to be used with eac3to ) of the new version ?

[LigH]

Not yet on RareWares; asked in Hydrogenaud.io for it. The media-autobuild_suite unfortunately builds different DLLs.

Might be impossible to get newer dcadec DLL's now that foo86 has moved everything to FFMPEG.

The git for FFMPEG should be more updated than GitHub.

commits from foo86:
https://git.ffmpeg.org/gitweb/ffmpeg.git?a=search&h=HEAD&st=author&s=foo86

commits about avcodec/dca in general:
https://git.ffmpeg.org/gitweb/ffmpeg.git?a=search&h=HEAD&st=commit&s=avcodec%2Fdca

Madshi might have to remove dcadec DLL's in favor of FFMPEG udpates.

Which means, we'd just have to wait for madshi to update his modified libraries whenever FFMPEG goes through major updates.

[tebasuna51]

The same for aften dll's, maybe are fast thanks to wisodev optimizations, but with the same problems than old aften (https://forum.doom9.org/showthread.php?p=1794293#post1794293)

The AC3 encoder included in ffmpeg is the preferred.

[wish_ihadalife]

Hello all,

I have been lurking the doom9 forums for quite some time now, and been experimenting to get eac3to work, but I am a little stuck.

Running a test on my command line, I am getting the following messages:

Thank you for all of your help. I usually use Headac3e and tsMuxer, but I am hearing this is a much better encoder. Would love to get started, thank you for your support!

Sorry for all the questions, just trying to get started!

[LigH]

Welcome.

Are Libav / ffmpeg the same program?

Depends on the desired meaning...

The ffmpeg project contains libraries for the handling of containers (libavformat) and contents (libavcodec).

During some stage of development, some developers split and created a fork of ffmpeg, named libav. It doesn't matter much, probably, from which fork you prefer to use the codec libraries as long as they are up to date, so they can handle modern HD audio formats as well.

Does anybody know where I can find/buy the Nero Audio decoder? As well as the ArcSoft and Sonic ones?

In most recent versions, the libav* libraries should be able to handle most formats with satisfying quality. To use 3rd party decoders, you would possibly have to have bought this software a while ago, or use "codec packs" regardless of software licenses... (see forum rules).

Also, which versions will work best?

Toughest question, regarding the ArcSoft decoder; several versions have different (dis-)advantages. I believe only "fanatic" audiophiles care. Home users won't recognize a difference to the results of libav* decoders while just listening in their living rooms, especially after compressing with another lossy format...

[sneaker_ger]

ArcSoft has pretty much been replaced by DcaDec. The only thing it cannot decode compared to ArcSoft is DTS Express and that's only because the version in eac3to is outdated. The newer one in ffmpeg can decode it.

[tebasuna51]

Nero Audio Decoder (Nero 6 or older) doesn't seem to be installed
ArcSoft DTS Decoder doesn't seem to be installed
Sonic Audio Decoder (3.31.0.0) doesn't seem to be installed
- DirectShow Nero Audio Decoder (not free) is only needed to decode audio AAC.
You can extract the AAC track from a .mkv and use other free tool (ffmpeg,...) to recode, if you need recode, most the times is better preserve the AAC track as is.
Install not free Nero 7 for only this function is not recommended.

- ArcSoft (not free) DTS Decoder is only needed to decode DTS Express (some comentary audio tracks in BD's) like sneaker_ger say.
Also ffmpeg can be used for that.
The included decoder (dcadec) is equal, or best, than ArcSoft for DTS standard and HD.

- Sonic Audio Decoder (not free) is not needed at all.
It was used at first time to compare outputs, but now it is not recommended.

You can work with eac3to without these 3 commercial soft's.

[nevcairiel]

dcadec can only decode the lossy stream "core"

This is wrong. libdcadec can decode the full lossless DTS-HD parts, even the "strange setup" streams that ArcSoft does not decode lossless in all cases.

Yeah, it seems as if you need a very early version of ArcSoft... I tried installing ArcSoft TotalMedia Theatre 6.7 and eac3to doesn't seem to pick up the DTS Decoder. Even when I moved it into System Folders.

IIRC, you may use the -arcsoft switch for forcing eac3to to use the well-known DTSDecoderDll.DLL.

OK, I downloaded the latest release version 0.2.0 (https://github.com/foo86/dcadec/releases), released on 4 Jan 2016. The warning message "XLL output not lossless" disappeared now!!!

But instead of 24 bits, the decoded file has 16 bits, with libDcaDec DTS Decoder and also with ArcSoft DTS Decoder :confused:

Thank you.

[Sparktank]

IIRC, all decoders for DTS (dcadec, arcsoft) do the same thing with "XLL output no lossless".
Except, they were all silent, so the only difference was that the recent dcadec allowed the message to be seen.

One user did make a custom build that just hid the message again for the placebo users who want that message "out of sigh of mind".

Arcsoft has so many versions, and no one has thoroughly tested the last version (1.09), so we can't really say if it behaves the same as previous versions or has different negative behaviours like some versions of Arcsoft.

For Arcsoft, v1.0.0.0 is the most known version to handle most scenarios.

But Dcadec should be the same and handle all formats (including Strange Setup, which Arcsoft requires a specific version) except for DTS Express.

[Sparktank]

[a03] The original audio track has a constant bit depth of 16 bits.
[a03] Superfluous zero bytes detected, will be stripped in 2nd pass.

Superfluous means "unnecessary", so it was really 16bit stored in a 24bit.

[Midzuki]

.........

But Dcadec should be the same and handle all formats (including Strange Setup, which Arcsoft requires a specific version) except for DTS Express.

dcadec 0.2.0 is really outdated. Since April of 2016, dcadec supports DTS Express, even the multichannel (5.1) streams.

https://github.com/foo86/dcadec/issues/33

[sneaker_ger]

The problem is development of the (external) dcadec library has stopped. It's all in ffmpeg now.

[nevcairiel]

eac3to already uses ffmpeg for other formats, so that wouldn't be a big hurdle - assuming madshi updates to a recent ffmpeg at some point in the future.

[tebasuna51]

Are you confusing Nero Audio Decoder and Nero AAC Encoder? (which I already have) Or are they similar in any way?

The Nero Audio Decoder needed by eac3to are Directshow filters included in Nero 7 package (plus a extra plugin). All not free, but there are some hacks to install the required filters without install the full Nero 7 package.

The Nero AAC Encoder (NeroAacEnc.exe) is a free standalone encoder than can be used by eac3to to output .m4a (AAC in mp4 container).
There are also a free standalone NeroAacDec.exe than can decode AAC inside mp4 container (.mp4 or .m4a), but can't be used by eac3to. You need run it in command line mode.

Yeah, it seems as if you need a very early version of ArcSoft... I tried installing ArcSoft TotalMedia Theatre 6.7 and eac3to doesn't seem to pick up the DTS Decoder. Even when I moved it into System Folders.

The lastest versions of ArcSoft don't have a required (by eac3to) checkactivate.dll. You need include this dll from previous versions to work with latest versions.

There are hacks (in this forum) to install the required (by eac3to) ArcSoft files without install the full ArcSoft TotalMedia Theatre package.

BTW, ArcSoft decoder is only needed to decode XSA / low bitrate (DTS Express in BD's), with the last libdcadec.dll you can decode any other DTS (standard or HD) the same (or better like with Strange Setup 7.1) than with ArcSoft.

Of course a great improvement of eac3to is (if possible):

- Add full dcadec decoder to support XSA / low bitrate, like is already in ffmpeg.

- Add AAC decoder from ffmpeg (maybe need some workaround to avoid license problems, similar to used with ArcSoft, Nero 7, Sonic or Surcode DTS)

- Add AC3 encoder from ffmpeg.

IIRC, you may use the -arcsoft switch for forcing eac3to to use the well-known DTSDecoderDll.DLL.

I did it! :thanks:

dcadec 0.2.0 is really outdated. Since April of 2016, dcadec supports DTS Express, even the multichannel (5.1) streams.

https://github.com/foo86/dcadec/issues/33

So, 0.2.0 is the latest version (and also outdated), right?

What decoder should I use to extract DTS Master Audio 2.0, 5.1, 6.1 and 7.1 now :confused: I was using ArcSoft DTS Decoder (1.1.0.0).

Thank you very much for all your help! :thanks:

[gonzalo76]

IIRC, all decoders for DTS (dcadec, arcsoft) do the same thing with "XLL output no lossless".
Except, they were all silent, so the only difference was that the recent dcadec allowed the message to be seen.

One user did make a custom build that just hid the message again for the placebo users who want that message "out of sigh of mind".

Arcsoft has so many versions, and no one has thoroughly tested the last version (1.09), so we can't really say if it behaves the same as previous versions or has different negative behaviours like some versions of Arcsoft.

For Arcsoft, v1.0.0.0 is the most known version to handle most scenarios.

But Dcadec should be the same and handle all formats (including Strange Setup, which Arcsoft requires a specific version) except for DTS Express.

Yes, Arcsoft, v1.0.0.0 is the version I'm using.

Superfluous means "unnecessary", so it was really 16bit stored in a 24bit.

Oops, I guess I made a newbie question, sorry!

Thank you very much for all your help!

:thanks:

To extract don't need any decoder.

To decode DTS MA let the eac3to default libdcadec.dll.

I am confused, please help.

Tried with several different files - got same result.
After conversion mpg -> mkv, m2ts -> mkv, mediainfo does not contain any info about audio stream.
But audio stream can be played in MPC-HC.

Here is an example.

Is your MPC-HC set up to search external audio sources with the same file name? Check the filters submenu whether the audio source is the loaded file or an additional file.

Audio source is INSIDE of the loaded file.

Please put the eac3to log.

I can't reproduce your problem, my log:

eac3to v3.31

there are 2 files the .ac3 and the .mkv (by size is impossible than contain the audio also)

[rivera]

there are 2 files the .ac3 and the .mkv (by size is impossible than contain the audio also)
OMG, seems I got the point!
The output file does not contain audio stream, this stream is demuxed into .ac3 file!
I thought that "eac3to input.m2ts output.mkv" generates ONE file which includes both video & audio streams...

Now I understand why I was asked about external audio tracks in MPC-HC.

Is there going to be any issues with extracting these tracks? Or anything special I should be doing?

[tebasuna51]

Extract as always and put the log. Seems a eac3to mistake.

[XadoX]

Is there a way while using windows PowerShell to output the eac3to options as list, like usualy with cmd?

[LigH]

You mean something similar to "eac3to > eac3to.txt"? This never really worked well, due to the strange output formatting used. I never understood why it is necessary to prepend every output line with 80 backspace chars. As if a CRLF is not enough to start at the left margin.

[XadoX]

I only ask because in Windows 10 1703 CMD is defaulty replaced by PowerShell.
While using Powershell with eac3to the output is not shown as list. Instead every output is shown only in the first line.
So I have to use a pipe like you explained and thats not realy comfortable.

Additionally, "Take Command" by JP Software (former 4DOS / 4NT) is an enhanced CMD-like command interpreter (Lite version is free to use).

It saved my day by avoiding surprises when comparing both LFN and SFN against wildcard patterns, matching more files than desired...

While you're at it, I like ColorConsole:

I recommend to redirect the eac3to help to a file, and load the file in a good text editor to remove the BS characters. Due to the extremely bizarre formatting options of eac3to, it's the only method that gives good results.
