eac3to - audio conversion tool

[tebasuna51]

I can confirm the problem, the:
"Removing DTS dialog normalization..."
only work, with dtshd input, when you use:

eac3to input.dtshd output.dts -core

And don't work with:

eac3to input.dtshd output.dtshd
eac3to input.dtshd output.wav
eac3to input.dtshd output.wav -libav
eac3to input.dtshd output.wav -core
eac3to input.dtshd output.wav -core -libav

BTW, if eac3to inform:
"DTS Master Audio, 5.1 channels, 16 bits, 48kHz, dialnorm: -4dB"

you can use this command line:

eac3to input.dtshd output.wav +4dB

Ah thank you....i think Madshi will fix it when he have the Time..
But as i say, please, can somebody write a small Tool or Batch to write the extra bytes back to a DTS-HD Header to restore the untouched DTS-HD Header :) Sadly ive no Skill to code something.

[AnryV]

"DTS Master Audio, 5.1 channels, 16 bits, 48kHz, dialnorm: -4dB"

you can use this command line:

eac3to input.dtshd output.wav +4dB

Unfortunately this will lead to the fact that we will not obtain the original sound. This will be especially noticeably for 16-bit tracks.

[tebasuna51]

Then use:

eac3to input.dtshd output.wav +4dB -down16

Of course is a workaround, but the process work at 64 bit float, do you think can be especially noticeably?
Maybe any rounding bit.

I don't know for what you need the wav's files.

Anyway this is the result of processing, but original sound.

[73ChargerFan]

The dts core is lossy, so 1-bit rounding errors could be considered immaterial.

[ACrowley]

So the DialNorm Problem doesnt exits when DTS-HD is decoded by Sonic Decoder ? Ofcourse it doesnt work on 7.1

[Snowknight26]

Reducing the bitdepth from 24-bit to 16-bit seems to cause tons of static. Tested on a 5.1 channel 24-bit WAV file. Should reproduce easily.

When I tell eac3to to give me the stream list from the main movie, it returns nothing :(

I can easily work around this by directly referencing the M2TS in question... Turns out there are two versions of the film on this disc, one with the original Russian cards (since it's a silent film), and another with English translated cards.

I prefer the Russian cards with English subtitles, so I just peeked at the M2TSs, and fully demuxed the one I wanted. Incidentally this was 00046.m2ts, and I was treated to the lovely PGS renderer that's now a part of MPC-HC!!! :D

I think eac3to's confusion may stem from the fact that the main movie M2TS files are preceeded by a very short M2TS, which is the Kino logo. But, I'm certainly not Madshi! Anyway, I was able to work around this no problem, but just a heads-up! Everyone should watch this BluRay. It's a great restoration of THE soviet film. Fantastic!

You have to do the actual file and not the playlist. It's the second one on each playlist. This is another one of the ones that we spoke about earlier.

BTW, if you do the English one you do NOT need the subs as they are the same as the placecards.

[`Orum]

Been using eac3to for quite some time now and love it...but I do have a couple of minor requests. First, an option to disable saving the internal logging of the output to a file--typically when batch processing I'll log everything to one file anyway. Secondly, a way to silence the completion "uncorking" sound. It's fairly loud and very annoying when running batch scripts to do some quick remuxing/conversion on lots of files. Other than that it's perfect.

Many thanks, I can't tell you how much time this app has saved me.

[Snowknight26]

Rename the wav files.

[`Orum]

yeah I know you can do that, but I find them useful at times...just thinking a command line flag would be best.

[Blue_MiSfit]

@Killroy:
Yep, that's what I meant to say :)

Regarding the content, I do prefer to see both the Cyrillic characters and the English subs as well. It feels more... soviet?

Thanks though!

Derek

[kypec]

yeah I know you can do that, but I find them useful at times...just thinking a command line flag would be best.
If you are annoyed by the sound only in your batch processing then why not try something like this:rem This goes somewhere before the eac3to.exe is called
rename "C:\Program Files\AVTools\eac3to\error.wav" error.none
rename "C:\Program Files\AVTools\eac3to\success.wav" success.none
rem Here goes your usual processing...
rename "C:\Program Files\AVTools\eac3to\error.none" error.wav
rename "C:\Program Files\AVTools\eac3to\success.none" success.wav

Replace path to eac3to with your real path of course.

[tebasuna51]

Maybe?:
"reduce bitdepth of decoded audio data by using TPDF dithering"

[`Orum]

Yeah, the disadvantage of that is you have to be careful with your batch files. E.g., if I have one batch file, "bat_1.bat", that is
rename "C:\Program Files (x86)\eac3to\error.wav" error.none
rename "C:\Program Files (x86)\eac3to\success.wav" success.none
.\otherdir\bat_2.bat
"C:\Program Files (x86)\eac3to\eac3to.exe" foo.mkv 2:bar.flac
rename "C:\Program Files (x86)\eac3to\error.none" error.wav
rename "C:\Program Files (x86)\eac3to\success.none" success.wav
and a ".\otherdir\bat_2.bat" that is similar, e.g.
rename "C:\Program Files (x86)\eac3to\error.wav" error.none
rename "C:\Program Files (x86)\eac3to\success.wav" success.none
"C:\Program Files (x86)\eac3to\eac3to.exe" foo2.mkv 2:bar2.flac
rename "C:\Program Files (x86)\eac3to\error.none" error.wav
rename "C:\Program Files (x86)\eac3to\success.none" success.wav
I won't get the intended silent result. Just need to be really careful of the order you do things in, and where you do the renaming. A flag avoids the ordering problems.

Hello everyone,

I hate to sound like a total noob, but I am having a big problem with eac3to. It simply will not convert TrueHD to LPCM. I'm trying to convert a bdrip for playback on my PS3. I do not know why, but it is specifically TrueHD that fails. I mean I just finished successfully converting a DTS-HD MA track to LPCM. I also know it's not a bad rip or anything because I've tried several different TrueHD tracks and none of them will convert. With a DTS-HD conversion I get the full sound, but with TrueHD I end up with no sound and really speed up and stuttery video.

If it helps I like to use multiavchd to convert my .m2ts files with DTS-HD / TrueHD to .m2ts files with LPCM. I get no errors with DTS-HD but TrueHD always throws the error that eac3to refuses to convert. Yes, I am running the latest version of both multiavchd and eac3to. I don't know what else I would need as eac3to is promoted as supporting TrueHD decoding out of the box without any additional files. I've searched high and low and I am at a loss on this one. I mean usually people have issues with DTS-HD to LPCM not TrueHD to LPCM.

Oh if it makes any difference I am running Windows 7 x64 with the latest windows 7 codec packages

[tebasuna51]

@DaFees
Please put the eac3to log.

[DaFees]

@DaFees
Please put the eac3to log.

I wish I could, but I'm not sure if I am getting a correct log. I ran multiavchd and that didn't provide a useful log. I did try running eac3to via commandline and it did give me a log, but I do not think it was helpful:

Try this

[tebasuna51]

@DaFees
Of course the log help to know the problem.

eac3to works fine and decode the TrueHD without problems, I don't know what is the problem with multiavchd.
Try with the w64 format like Atak_Snajpera say you.

[DaFees]

Try this
C:\multiavchd\tools\eac3to\eac3to.exe "D:\BD Wip\00001.track_4352.ac3" "D:\BD Wip\00001.w64"

Well I tried this and I even remuxed with tsmuxer and when I tried to play the final video I got no sound and stuttery video, again.

Still though eac3to still told me all was well:

eac3to v3.21
command line: C:\multiavchd\tools\eac3to\eac3to.exe "D:\BD Wip\00001.track_4352.ac3" "D:\BD Wip\00001.w64"

I should add that multiavchd will play the error sound that comes with eac3to every time it refuses to convert the audio.

[tebasuna51]

Play D:\BD Wip\00001.wav to listen the audio, if play ok put your problem in multiavchd thread (http://forum.doom9.org/showthread.php?t=143744) because eac3to seems work fine.

[DaFees]

Ok well I just checked and eac3to is working fine, because the .wav file played fine on my PC and yes I will post in the multiavchd thread for help, but that still doesn't totally resolve the issue. Ok, so multiavchd won't work. Well then why won't my converted audio stream when remuxed with the video play on my PS3?

I've tried the conversion two ways: Using multiavchd and tsmuxer gui to demux the audio + eac3to to convert to lpcm + tsmuxer gui again to remux the converted audio with the video.

[madshi]

The mapping of 3.0 soundtracks converted to flac is incorrect. The center channel ends up in the left surround.
Can I have a short sample, please?

If that is the case, perhaps it would be a good idea for eac3to to simply decline the encoding of 3.0 files to flac for the time being.
No, I will not limit eac3to just because decoders don't behave correctly. Instead the decoders should be fixed.

A feature request for two options:

-cutF (cut at frame)
-cutT (cut at HH:MM:SS.MLS) (or any variation using time format)
Are you talking about audio or video? Cutting how much? Have you tried the "-edit" option?

eac3to don't remove the dialog normalization with Arcsoft decoder (1.1.0.1)
Can I have a DTS-HD sample with dialnorm, please? Don't know if I can fix this. Maybe yes, maybe no. Editing the DTS-HD headers is very complicated.

Reducing the bitdepth from 24-bit to 16-bit seems to cause tons of static. Tested on a 5.1 channel 24-bit WAV file. Should reproduce easily.
I'm getting that too and also on a normal 16-bit 7.1 TrueHD to FLAC conversion.
Sorry about that. One of the v3.21 fixes caused this. Will be fixed in the next build.

I'm seeing odd behavior with Battleship Potemkin
Another Blu-Ray I don't have. Would it be possible to upload the first small m2ts file and the first maybe 10MB of the movie m2ts file, together with the PLAYLIST and CLIPINF folders?

First, an option to disable saving the internal logging of the output to a file
Is the creation of the log file such a big problem? After all, you can simply delete it again!

Secondly, a way to silence the completion "uncorking" sound.
yeah I know you can do that, but I find them useful at times...just thinking a command line flag would be best.
Nope, sorry. I don't like the idea of adding tons of funny options that must be documented/explained somewhere. That makes eac3to usage only more complicated. BTW, when writing batch files you can use stuff like "if exist success.wav goto :someMark". That should fix all "order" problems.

Ok well I just checked and eac3to is working fine, because the .wav file played fine on my PC and yes I will post in the multiavchd thread for help, but that still doesn't totally resolve the issue. Ok, so multiavchd won't work. Well then why won't my converted audio stream when remuxed with the video play on my PS3?
So there's a bug with multiavchd and another bug with tsmuxer. Why are you asking for help about these tools in the eac3to thread? As you said yourself, eac3to seems to be working fine.

eac3to v3.22 released

http://madshi.net/eac3to.zip

* fixed: reducing bitdepth from >16bit to 16bit resulted in static (v3.21)
* updated to latest ffmpeg/libav version
* libav MP1/MP2/MP3 decoders now decode to floating point
* libav E-AC3 decoder now supports spectral extension
The updated ffmpeg/libav libraries are quite a big change. It would be nice if you guys could do some libav decoder testing with various codecs (AC3, E-AC3, DTS, MP1, MP2, MP3, MLP, TrueHD) to make sure that things still work as intended.

[deathlord]

Hi

I have just encoutered a nasty problem using eac3to 3.17.
When converting 5.1 48kHz dts files to 5.1 flac, eac3to just stopped without error, leaving an unfinished file and no log. It happen only with one file out of ten.
Even worse, rerunning the identical command line once more, the problem does not appear anymore.
This has happend twice in the last couple of days.

Any ideas?

Unfortunately I was unable to reproduce this problem. I could run two instances of eac3to using arcsoft at the same time.

Probably there really was (is) something wrong with my PC...

Another thing:

How can I silence the last 3 seconds, say, of a flac file? Is there a way to use the -edit function to do this without manually entering "runtime minus 3s"?

I would like to systematically silence the annoying sound at the end of tv shows.

Cheers

Eac3to, or likely the ArcSoft decoder, doesn't seem to like my one channel DTS file. I want to convert it to 192kbps ac3 as one channel DTS seems like a massive waste of space.

Check the first post, check the readme, check by running eac3to without any parameters. Kind of hard to miss.

In this case i use Megui to encode the dts-file.

He's encoding AC3, not DTS, so that wouldn't help.

[ACrowley]

@madshi

When you anyhow take a look into the DTS-HD Header because of the DialNorm Issue, can you add a Routine into eac3to to restore/strip the DTS-HD Header ?

..new libavcodec is faster on AC3 and EAC3, Great! EAC3/AC3/THD looks good with libav so far i can see

the error in encoding to .ac3 is related to 5.0 channels...

Hi Madshi,

Thanks for reading my bug report, and being willing to take the time to fix the problem!

Here's the samples you requested for Battleship Potemkin:

nope...as I said, all is fine with FFmpeg. I mean transcoding eac3 to ac3 of course.

[Snowknight26]

It's because its only 5 channels. The implementation of Aften that eac3to uses doesn't take non-standard channel masks. If you have eac3to output to stdout, you can pipe the data to standalone Aften and it'll work.

[mrr19121970]

I don't think that's the issue in this case. The problem might be because the 2 files do not contain the same track structure.

Will you test this for me with Mary & Max

Sure, I tested and it doesn't appear to work..It does not report a DTS-HD audio track in the playlist. I didn't see that madshi fixed it in his release notes.

nope...as I said, all is fine with FFmpeg. I mean transcoding eac3 to ac3 of course.

Transcoding 5.1 E-AC3 track with spectral extension to 5.1 AC3 track seems to work well now with eac3to.

Transcoding 5.0 E-AC3 track with spectral extension to 5.0 AC3 track does not work. But this is probably more a problem with encoding only 5 channels than deconding 5.0 E-AC3 track with spectral extension.
If we could have a fix to be able to encode 5.0 tracks in AC3, that would be great because in the past one of our french channels used 5.0 E-AC3 audio instead of 5.1 E-AC3. So currently some of our old recordings are not yet managed by eac3to.

Yes, same result, converting to WAV is done by eac3to without errors and the produced WAV contains 5 channels.
Error occurs when trying to encode in AC3.

Here is a 50MB sample of dtsma 3.0, as requested. The first 30 seconds are silent, this is normal.

Apart from the "imperfections" :devil: of the ArcSoft Decoder,

255kbps would have been more-than-adequate. :helpful:

try "-libav" instead of the ArcSoft filter,

something like this ?

eac3to.exe input.ts 2:output.stdout | aften.exe -readtoeof 1 - aften.ac3

if yes, this doesn't seem to work...
