Same here.

The "3dB Attenuation" is also an option in the encoder GUI, AFAIK it's for rear-channel attenuation.

I'm using 1.0.21, so ACrowley's version is probably newer. Or it's a different product than "Surcode DVD Pro".

I use Surcode DVD DTS Pro 1.0.23

I will Test it. But what i know surely is that changing the DynamicCompress Reg.Setting has no Effect!
The wave has same Peaks compared with DRC off encoded

@Madshi
You say in the Screenshot its -27db ? I dont know how to set the DialogN. Values with Registry (Hexa)Dezimal Values ?
Then i can Test it

Use Windows calc. Enter "-27", then switch to "Hex". You'll get 16 chars. Cut off the first 8. The last 8 chars is what you need to put into the registry.

I made a Test with Surcode dts pro 1.0.23 and the DialogNorm Registry Settings.

http://img66.imageshack.us/img66/6021/sshot3mi9.th.png (http://img66.imageshack.us/my.php?image=sshot3mi9.png)

All dts are decoded to wave with Tranzcode 0.4b

Theres absolutly no difference when i change the RegistryValues fro Dialog Normalization
And not whne changing Dynamci Compress

So it has no Effect so far i can see

Maybe Tranzcode ignores these values? Does Tranzcode ignore DialNorm for AC3 decoding? I think ffdshow would be a good test decoder cause it executes DialNorm for AC3 decoding, IIRC.

Another useful test would be to check if those DTS files are bit wise identical or whether there are any bytes different. If the DTS files are 100% identical then no decoder on earth can output a different result for the 3 DTS files.

I test with SurCode DVD Pro DTS v1.0.23.

1) Initially i don't have "DIALOG NORMALIZATION" at register

2) With "DIALOG NORMALIZATION"=dword:ffffffe5 (-27)

3) With "DIALOG NORMALIZATION"=dword:ffffffe1 (-31)

the three dts are bit identical.

BTW, in encoder options I can only choose:

-Data Rate:
1536 -> "DTS BITRATE INDEX"=dword:00000001
768 -> "DTS BITRATE INDEX"=dword:00000002

-Sample Rate:
48000 -> "SAMPLING RATE"=dword:00000000
44100 -> "SAMPLING RATE"=dword:00000001

-Attenuate rear channels 3 dB:
Yes -> "SURROUND DOWNMIX"=dword:00000001
Not -> "SURROUND DOWNMIX"=dword:00000000

Don't know why that happens. It seems to work for everybody else? Do you have the Blu-Ray/HD DVD plugin correctly licensed/registered? And are you using the latest Nero version?

Err... I updated eac3to and I'm getting the same error messages.

ACrowley

31st July 2007, 12:19

@madshi

Tranzcode applies no DRC..thats sure
But i think DialogNormalization ,as like as ffdhow

But with AC3 Filer the decoded dts are always at bit higher Peaks (a bit), SO ithink AC3 Filter applies no DRC, no Dialog Norm
However, these 3 Test Samples are identical with all decoders..no Effect when changing the Values in Registry

madshi

31st July 2007, 12:32

the three dts are bit identical.
Argh. Ok, thanks for testing!

Are you absolutely sure that DTS really knows Dialnorm at all? I rather doubt it right now. After a google search it seems to be that DTS doesn't have a Dialnorm like feature.

Madshi , im not sure
Look at here, its a Comparion from original dts Source decoded with all Decoders :
http://img123.imageshack.us/img123/42/46819065qo5.th.png (http://img123.imageshack.us/my.php?image=46819065qo5.png)
AC3 Filter has higher Levels..

This is a Comparions from AC3Filter Source with a Surcode reencode with -10db DialogNorm RegistryValue
http://img66.imageshack.us/img66/7116/84926638sa7.th.png (http://img66.imageshack.us/my.php?image=84926638sa7.png)

No difference.
When it would be possible to change DialogNorm via Registry for Surcode ,there must be a visible Difference

Read here (from Hardware Sound Processor)
http://www.hometheaterhifi.com/volume_4_3/meridiandts.html

DTS also does not have flags that support late evening listening (compression) or dialog normalization, while DD does.

Then it makes sense why Surcode output is identical with DRC/DialogN Reg.Values On or Off, and AC3 Filter is only a bit louder

Also i was wondering why honai told us his AC3 Tracks are louder as dts..it should be reversed.

honai

31st July 2007, 13:17

What I meant was that typically my receiver plays DD louder than DTS, but with the new eac3to the transcoded DTS tracks were louder than the same DD tracks from retail DVDs.

yes..i know
And i was only wondering why typically dts is always louder as ac3 :)
Ofcourse the decoding from eac3to 1.10 is "louder" now , because it preserves the full dynamics instead of older Version with full DRC/Dialog.
So your dts reencode has more dynamics/is louder too. I think a AC3 reencode from EAC3 is closer to the Source. Surcode isnt the best Encoder ....

Of course DTS have DialNorm and DRC like you can see in DTS Coherent Acoustics; Core and Extensions (http://webapp.etsi.org/action/PU/20021224/ts_102114v010201p.pdf) (pag. 14 and 17)

"Embedded Dynamic Range Flag V DYNF 1 bit
DYNF indicates if embedded dynamic range coefficients are included at the start of each sub-frame. Dynamic range correction may be implemented on all channels using these coefficients for the duration of the sub-frame."

"Dialog Normalisation Parameter/Unspecified V DIALNORM/UNSPEC 4 bits
...
The dialog normalization gain (DNG), in dB, is specified by the encoder operator and is used to directly scale the decoder outputs samples. In the DTS stream the information about the DNG value is transmitted by means of combined data in the VERNUM and DIALNORM fields (see table 5.22)."

Other question is if a encoder use these features.

madshi

31st July 2007, 15:24

Hmmmm... Thanks for the PDF, it's helpful, although a bit confusing. I'll do some more tests later when I have more time.

ACrowley

I Made more Tests.
The Surcode DTS Pro 1.0.23 Registry Settings for DialogNorm and DRC have no Effect

madshi

31st July 2007, 16:24

Ok, the next test would be to check which dialnorm value Surcode writes into its DTS encodes and to manipulate this value and see if it shows any effect with any decoders.

EvoDemux shows the timestamps (PTS) of the first video and audio packets. If they don't match, you can calculate the delay from that.

madshi, is it possible to have eac3to output a new DD+ track with dialnorm (and maybe DRC?) removed? It would be a great option for realtime playback of DD+ tracks without the step of conversion.

madshi

31st July 2007, 21:59

madshi, is it possible to have eac3to output a new DD+ track with dialnorm (and maybe DRC?) removed? It would be a great option for realtime playback of DD+ tracks without the step of conversion.
Removing the DRC information from the DD+ track would be theoretically possible, I think, but much harder than removing DialNorm. Removing DRC would mean parsing through the full DD+ structure, which is relatively complicated. And if there's a parsing bug, the DRC removing would destroy the DD+ track. Because of that I'd rather not do that. Removing Dialnorm is oh so much easier, because it's right at the beginning of each audio frame, so not much parsing is needed and there's no big danger for bugs. I could easily add an option to give out a modified DD+ track without DialNorm. Actually you can do that yourself already: Just ask eac3to to convert the DD+ track to e.g. "raw". Then during the decoding phase you can copy the "something.tmp.ddp" file. This temporary file is a full copy of the original DD+ track, just with DialNorm turned off.

But I have to say that defeating DialNorm alone doesn't make much sense, as long as DRC is still active, because DRC is the much worse problem.

Rectal Prolapse

31st July 2007, 22:01

Ah, thanks madshi! :)

For realtime playback, is Nero Audio Decoder the best solution right now?

Daodan

31st July 2007, 22:21

Sorry to interrupt this lenghty DRC/normalize talk, but does anyone know a method for decoding truhd from mt2s files? No splitter I have sees that (sonic, nero, cyberlink, etc). Only xport can demux but that doesn't help much as I don't think there is a filter source for that.

madshi

31st July 2007, 22:28

For realtime playback, is Nero Audio Decoder the best solution right now?
I think for realtime playback I'd use the Sonic one right now. It seems to be a bit less bad than the Nero one in terms of DRC. But maybe you should better use ShowTime or PowerDVD. That way you could get around DRC.

does anyone know a method for decoding truhd from mt2s files?
Haven't tried that yet cause I haven't run over a TrueHD Blu-Ray yet. But I know they are beginning to appear.

Daodan

31st July 2007, 22:37

Here's a piece: http://d01.megashares.com/?d01=2209572
Track 1 is 5.1 truhd. I found smth intersting with that, will post after a few more tests (I managed to get some sound out of it, but has some crackling in it).
Also Sonic demux sees the demuxed truhd with xport...only problem is that nero audio can't connect to that...

Rectal Prolapse

31st July 2007, 23:26

I read that Blu-ray TrueHD tracks have a DD5.1 640 kbps track interleaved with the TrueHD stream. It is NOT a core track, but a separate track.

madshi: Unfortunately, I have major PQ issues with PowerDVD, and showtime crashes on a lot of blu-ray titles. Oh well. I guess I'll stick with Sonic for now, or actually use eac3to for what you designed it for and mux my own. :)

Daodan

31st July 2007, 23:30

Yeah, that's probably why I manegd to get some sound. Having it interleaved sounds like a lol idea, why would they do that? Just because the crappy players don't support truhd?

eac3to 1.12 released

http://madshi.net/eac3to.zip

(1) The tools "flac.exe", "aften.exe" and "sox.exe" are now distributed in the eac3to zip to make your life a bit easier.
(2) Correct channel mapping for 7.1 LPCM tracks is default now.
(3) The new option "-down6" allows downconverting of 7.1 tracks to 5.1 (this option is activated by default for AC3 and DTS encoding).
(4) I'm shipping a modded "flac.exe" with eac3to now, which has no problems with 2GB file output, anymore!! As a result the flac encoding by eac3to should now be more or less perfect.
(5) Fixed a number of bugs.

Btw, those Blu-Ray soundtracks which say 6.1 LPCM are actually 7.1. Ok, two channels are identical, that's probably why the cover sais 6.1. But the LPCM track contains full audio data for 8 channels. So use the "-8" switch for 6.1 LPCM tracks.

It's a "full version". The pas etc files are the source code of eac3to, which is now in the sub folder "sources". You can delete this "sources" folder if you don't need/want to have the source code of eac3to. You should keep the other subfolders and files. Ok, you can delete sox, if you don't plan to downconvert anything from 24bit to 16bit. And you can delete the aften/flac sub folders, if you don't ever plan to use eac3to to encode ac3/flac.

ACrowley

6th August 2007, 10:43

ok, thx

On more suggestion, maybe you should note in eac3to.exe that Sonic Decoder will apply DRC and DialogNormalization, that you can only avoid it with NeroDecoders.
Sure, we here know it, but for other Users its more obvious

And, for bluray lpmc to wave , do i need still the -bluray parameter ?
Or works the Auto CHmapping for lpcm too ,as like as for eac3/TrueHD(when i want standard L=0 R=1 C=2 LFE=3 SL=4 SR=5 ) ?

EDIT:
Nice work!! lpcm24bit to flac 24bit works perfect! With Timeline and no 2gb Restriction!
Older eac3to Version outputs always a 24bit flac which was corrput8 to big, only noise) but now it works !

E-AC3 DialNorm is fully defeated by eac3to, doesn't matter which decoder you're using. But I should probably add a warning about DRC with Sonic's decoder, I agree.

Channels should automatically be mapped correctly for every kind of input, unless you have a strange input. For Blu-Ray PCM I expect the data to be demuxed by xport or TsRemux, though. If you use the GraphEdit dump method to demux a Blu-Ray PCM track, you'll have to set different parameters in eac3to, e.g. endian will be "little" instead of big etc...

But thats not my Experience....All LPCM Tracks i have demuxed with SonicHDDemxuer/graphedit are working with BigEndian.
Shouldt eac3to detects autom wich Endian it is ?
When i set no Endian Switch the Output is ok

And your tweaked flac.exe...is it working only eac3to intern or can i use the 2gb workarounds outside eac3to ?

I'm quite sure it's no DialNorm with the later eac3to versions. But probably DRC + gain.

Strange. Well, that's just fine.

I can try to add auto Endian detection.

And your tweaked flac.exe...is it working only eac3to intern or can i use the 2gb workarounds outside eac3to ?
Of course that tweaked flac.exe works just fine on its own, but I will not tell you that, because I want eac3to to gain world domination... :)

P.S: That said, I've fixed the *output* 2GB limitation. The *input* limitations are still valid. You can work around them by feeding flac.exe though stdin (that's what eac3to is doing), but it's not very comfortable to do that manually.

ACrowley

6th August 2007, 19:29

Ok thx
Yes ,youre Right. Sonic Output looks more like DRC+Gain, very bad

Ah, Ok...It works everytime for me because Big Endian is default and all my LCPM are Big Endian as i say even demxued with Graphedit
Autodetection would be nice.
I know that SonicHDDemxuer output should be little Endian..But its reversed, with little Endian i get garbage on 24bit lpcm
Maybe the older 4.2 Demxuer outputs little E.

And i was talking about flac "output limitation"

I have a 24bit-5.1ch-48kHz-big.endian lpcm file and I tried converting to a flac.
The info about the lpcm file is from the output of xport

LPCM Audio Mode = 3/2+lfe
LPCM Audio Bits/sample = 24
LPCM Audio Sample Rate = 48000

So, I figured I don't have to use any option above and used this simple command line.

eac3to "the.wild.LPCM24.pcm" "The.Wild.flac"

This is what eac3to says;
Tried to find out the bitdepth automatically, but the algorithm failed.
Please use either "-16" or "-24" to tell eac3to which bitdepth the source has.

probably auto-detection is default instead of "-16" or "-24"?

Is it possible to convert truehd 8 channel from either inside an evo or demuxed to a pcm file and then I can use each3to to convert that to flac 7.1 audio file? I did try renaming the demuxed mlp file to .pcm but it only picks up the first 21-22 minutes of the movie instead of the full 2 hours worth which all the dolby digital plus tracks do. If I can somehow convert that truehd 8 channel track to pcm 7.1, then I can use each3to to convert it to a flac 7.1 audio file.

madshi

6th August 2007, 20:56

The Nero TrueHD decoder can only do 5.1. And the Sonic TrueHD decoder is totally unusable. So currently I don't see how you can decode all 8 channels of a 7.1 TrueHD track.

And PowerDVD can play eac3 ofcourse , but only in evo, as like as TrueHD only in evo

With winddvd8 no Truehd possible (only fileinfo)

Use sonic audio decoder 4.2.0 instead and add -sonic to the command arguements when encoding, then it should work.

I must have the same problem with my install because I get the same error consistently. I don't have the HD plug-in, but I understand that's only necessary for TrueHD.

I might just have to call Ahead and try and get my money back.

I would say Nero is necessary for EAC3 to, cause ist the only Way to keep the full Dynamcis

Try to rebuild the Evo with only your desired Audio and run eac3to onto it . I think its only your Audio File

Thanks for the great tool, madshi! Would it be possible to add a -dtswav option? I get mkvmerge errors when I attempt to mux a .dts file but a dts .wav file works okay.

dts2wav.exe doesn't appear to handle 48k / 24-bit .dts files so adding it to my batch file won't help.

-Cal

Edit:
or perhaps the syntax

eac3to.exe <inputfile.xxx> <outputfile.wav> -1536

and

eac3to.exe <inputfile.xxx> <outputfile.wav> -768

could be supported to produce a dtswav output file. Curently, it results in an error.

"Bitrate "1536" is only allowed for DTS encoding."

Don't know if this has been resolved somewhere in the thread but I had this problem and resolved it so I'm posting how I fixed it.

When trying to decode anything to wav (ddp or mlp) I got this:

E-AC3, 5.1 channels, 2:12:32, 640kbit/s, 48khz, dialnorm: -27dB
Remove Dialog Normalization information. Please wait...
Muxing eac3 file to raw. Please wait...
Disabling DRC for Nero E-AC3 decoding...
The file size of the raw file doesn't seem to fit.

Finally I discovered the actual problem was the dtsac3source-full.ax file which was corrupted or something. I had the same exact version on another computer which I had downloaded a couple of weeks before. That one was working, I knew, so I unregistered the old one (don't know if this is necessary)...

regsvr32 /u C:\WINDOWS\system32\dtsac3source-full.ax

...got the new one, and it worked.

If your raw file is 0 bytes and then eac3to crashes, chances are this is your problem.

Get some new dtsac3source from some different mirror or download site, register it and try again. That worked for me.

The version I have is 1.0.0.1, BTW.

Hope this helps.

That's interesting - thanks! I'm wondering why it happens in the first place, though, because eac3to by default doesn't even use the dtsac3source filter! The filter is only used if you use the "-orbitlee" switch or if the "Nero File Splitter" fails to work. Usually the Nero File Splitter should work just fine.

DTS Compact (.cpt)
DTS Padded (.dts)
DTS WAV (.wav)

11th August 2007, 01:33

Thanks for answering madshi's question, tebasuna51. Yes--Surcode allows the GUI user to specify the target file as a .wav file but the .wav contains DTS code rather than the more common PCM or, as you point out, other code.

The only other time I've used dtswav was when I played around with authoring a DTS audio CD. Using dtswav, it was possible to use conventional audio CD burning software--just burn the DTS .wav files like PCM .wav audio files. Now I'm interested in the dtswav format to cleanly mux DTS without errors or audio stuttering using mkvmerge.

Does anyone know a method for decoding truhd from mt2s files? No splitter I have sees that (sonic, nero, cyberlink, etc). Only xport can demux but that doesn't help much as I don't think there is a filter source for that.

I tried some things with a blu-ray trueHD track, but no luck so far.
The file demuxed by xport can't be imported in Scenarist (Scenarist sees it as an AC3 track and refused it because the bitrate is above 448Kb).

However, the file demuxed by xport is seen as a dolby trueHD track by Sonic HD Demuxer in graphedit. So I tried a dump with the graph FileSource(async) -> Sonic HD Demuxer-> Dump. The resulting file is a couple of Kb smaller, and still can't be imported in Scenarist, but the error is different : "Maximum frame size of MLP Audio file exceeds HD DVD limit.", so Scenarist sees it as a TrueHD track, but the file header is certainly wrong...

Right. And since eac3to can now remove dialnorm information from AC3 tracks, too, there should be even more stable methods. E.g. ffdshow should now work, too, I think.

If you used eac3to v1.12 or v1.13, Nero is the default TrueHD decoder. DRC is not applied by Nero's current TrueHD decoder at all (as far as I can say). So there's nothing eac3to had to remove. You can assume that Nero was used and that all went fine.

If you want to do frame correct cutting, you can drop the track into delaycut. It will tell you how many bytes per frame that AC3 track is using. I'm not sure what I need. I'd suggest that you try copying the first 2MB into a new file. Then simply check whether eac3to fails on that. If yes, those 2MB will be plenty enough. Heck, even 500KB would be enough, as long as the little chunk makes eac3to fail.

Strange, I'm not getting this problem on my PC. Are you encoding with 768 or 1536? I'm always using 1536. Maybe that's the difference? Anyway, I think this is a job for Mosu to fix - unless the DTS file is really buggy.

The "wav" format can't really properly handle files > 2GB (or was it 4GB?). I guess that's the problem you're having. eac3to usually works around this problem. Some other software packages do that, too. But some do not. I recommend to directly recode the E-AC3 track to either AC3, DTS or FLAC with eac3to. This way you should get a proper result. If you want to use a different AC3 encoder, you'll have to find out how to make that AC3 encoder properly handle big "wav" files. Or maybe you can use 6 mono "wav" files instead of one big 5.1 file. That should help, too.

tebasuna51

15th August 2007, 13:28

The "wav" format can't really properly handle files > 2GB (or was it 4GB?).

The wav format can handle until 4 GB.

The limit is two fields with 4 bytes (to store filelength and datalength) only can support values until 2^32.

The 2 GB limit is a wrong soft than read/write these 4 bytes with signed int then the limit is 2^31 -> 2 GB, if the fields are read/write with unsigned int the soft can manage until 4 GB.

The workaround to support wav > 4 GB is ignore these two fields in wavheader and read until end of file. The only problem is if the wav file have extrachunks (some extra info) after the audio data, then are converted also to audio with final clicks.

The best way depend of final format/encoder, if you use ac3/Aften or aac/NeroAacEnc you need use a wav multichannel > 4 GB and inform the encoder with -readtoeof 1 (for Aften) or -ignorelength (for NeroAacEnc)

Other format/encoders must need separated channels in monowav's.

Thanks ACrowley for the reply. I had read the above threads. The method 1 is ok but in method 2 there is not an accurate way to measure the right Dialog Norm. value.

I wonter why you say "Dont set it to the same Value for the reencoded AC3", i suppose that the .eac3 file had the correct Dialog Norm value. Correct me if i am wrong.

Maybe you have mistaken something..
You, should not use the DialogNormValue from the AC3/EAC3 Source (if AC3 or EAC3), right.
Reencoding with -31db (dont care about Source Value) and "no" DynamicRange Profile will guarrante the Input Wave Volume Level with uncompresssed Dynamics.

But it has nothing to do with wrong EAC3 Input Values (by the Way,they are not wrong) :), its only a guideline for reencoding and nothing else :)

Ofcourse you can measure the RMS accurat enough. Just use the Center Wave with a Dialog Part . Use Adobe Audition and you will get a Value which is accurate enough to use it for DialogeNorm in your AC3 reencode .In this Case you have to use a DynamicRange Profile. Otherwise it makes no Sense.
As i say , its the full DolbyCompliant Method to encode AC3..

But i ,and most guys i know ( eac3to too) are using the -31db with no DRC Method. Its sounds best on my Receiver/Setup

@Madshi
I have a few eac3 Tracks ( FullMetalJacket HDDVD) with Problems when removing DialoNorm with eac3to. eac3 starts with removing DialNorm...and after a few seconds the whole Process stopps without Error Message. It works with DialNor enabled

Why ?

ACrowley

16th August 2007, 10:32

Why ?
http://forum.doom9.org/showthread.php?t=56020

The following point, however, cannot be stressed enough: In order for the Dynamic Range Compression to work as designed, the Dialogue Normalization parameter MUST be properly set first!

I should better say "makes more Sense" .
When you want a Dolby Compliant AC3 ,use DRC .
But DRC needs a proper DialogNormlization Value = RMS calculated

When you use no DRC ,-31db is the Best Value to keep Wave Source Dynamic/Volume ( lange Rede lurzer Sinn, thats all what counts for me)
So why should i touch the -31db Value , "without" a DRC Profile. -31db makes "more Sense" because i dont change anything
There are these 2 Methods to reencode to AC3. Taker the one "or" the other Method...thats what i mean :)

PS
you know, my English is very bad an i cant say everything i want in english

Yeah. So DRC needs DialNorm to be set correctly. But where is it written that DialNorm needs DRC to be set?

So why should i touch the -31db Value , "without" a DRC Profile. -31db makes "more Sense" because i dont change anything
Either you want DialNorm or you do not want it. If you want it, you tell the encoder to set it to the desired value. If you do not want it, you tell the encoder to set it to -31db. I don't see what DRC has to do with this.

There are these 2 Methods to reencode to AC3. Taker the one "or" the other Method...thats what i mean :)
Or take the third method which is to set a proper DialNorm value but not use any DRC. I don't see any reason why this shouldn't be used.

Well, personally I don't like neither DRC nor DialNorm. But I can understand if other people like DialNorm. So why forcing them to set DRC, if they only want DialNorm?

madshi

16th August 2007, 12:04

I PM'd you 2 examples of AC3 files that crash eac3to when removing DialNorm.
eac3to expects clean AC3 files. It aborts if there are errors in the AC3 file. The 2 examples you sent me were not clean. Please run them through besweet or delaycut to fix all the CRC errors etc. Afterwards eac3to will handle these files just fine.

Thanks madshi and ACrowley for the explanations.

@madshi when i set a value of Dialog Norm. -27 db without DRC then the decoder simply attenuate the whole stream by [31 + (-27)] = 4 db.

I made a test with the audio from the "RIO Bravo" movie (.eac3 mono, -27 db Dial. Norm). I convert to mono .wav with eac3to.

eac3to without any parameter:
peek value --> -1.1 db, RMS value --> -28.2 db

eac3to with -keepDialnorm:
peek value --> -5.1 db, RMS value --> -31.4 db

eac3to with -keepDialnorm and -allowDRC:
peek value --> -9.4 db, RMS value --> -32.4 db

The above values taken from whole stream, not from a part. I use Sound Forge with "ignore sound below -45 db" and "use equal loudness contour".

@ACrowley "Just use the Center Wave with a Dialog Part" it's not enough. We must use several parts from Center Wave with Dialog only and calculate the average RMS because there are high volume Dialog parts and low volume Dialog parts.

Correct. That's how DialNorm works... :)

16th August 2007, 14:56

Just my opinion:

- DialNorm: is a tool to equalize volume from different sources. If you only listen ac3 sources is a valid option to maintain the volume control at same position. If you listen also modern CDA music, commercial TV, mp3, ... use DialNorm -31 dB (and maximize peak to 0 dB).

- DRC: useful in bad listen environment (neighbors, night, bad audio equipment, ...). Recommended, if your audio equipment is bad you need them, if is good you can disable/enable at your choice. Remember, the audio is equal encoded, only attenuation/gain values are added and the decoder can use or not.

eac3to generates a wrong wav file

source is 16bit 48khz 7.1ch Blu-ray lpcm and tried converting to ac3.

command line and output is:
F:\eac3to>eac3to f:\Innocence.pcm f:\Innocence.ac3 -8 -16 -down6
RAW, 7.1 channels, 0:01:00, 16 bits, 48khz
Converting the raw file to wav. Please wait...
Converting the wav file to ac3. Please wait...

Aften: A/52 audio encoder
Version 0.07
(c) 2006-2007 Justin Ruggles, Prakash Punnoor, et al.

invalid RIFF id in wav header
invalid wav file: -b
"aften" reported error code "1". A valid *.wav file was created sucessfully, though.

this wav file eac3to created crashes mpc.

mediainfo says;
Codec : PCM
Codec/Family : PCM
Codec/Info : Microsoft PCM
Bit rate : 6144 Kbps (should be 4608 Kbps?)
Channel(s) : 6 channels
Sampling rate : 48 KHz

Thanks for the information. I've checked and the "-down6" option results in some fields being set incorrectly in the wav header. I'll fix that in the next build. In the meanwhile you could try using the Aften build that ships with eac3to instead of 0.07. I'm not sure if the older Aften build ignores the incorrect wav header but there have been cases before where the older Aften build worked fine where Aften 0.07 failed.

same thing happens with the Aften build in eac3to.zip.
rev.561 of Aften does create a file which is just stereo@640k and produces only noise.

@Nikos..i know :) When its a full lengt Track you cant use only a small Part.

However.. i dont use DRC and no DialNorm.. i encode with -31db ( -31db +31db = attenuate 0db) and no DRC Profile

One more question:
If one ac3 file has Dialog Norm. and DRC, the software ac3Filter bypass them or not?

No, it's not, it's precisely the answer to your question. ;)

The DRC option in AC3Filter allows for respecting or ignoring the DRC data in the AC3 stream.

If you set AC3Filter to passthrough AC3 to an external receiver of SPDIF then the receiver (or your hand at the remote control) decides whether DRC should be applied.

IOne more question:

I don't know DialNorm (is not a problem a fix attenuation), but, in accordance with my test, the DRC values in ac3 stream are bypassed and ac3filter apply a owner function to make the DRC.

This kind of function can be applied for any source, not only ac3, and is a better solution than ac3 DRC but require more resources, is not habitual in receivers or standalone players.

Of course anybody can do anything, but "DRC makes only Sense with proper Dialnorm" ???

The values of DRC are modified by DialNorm but the concept is absolutely different:

DialNorm try to normalize all the sources at same level (dialogs at -31 bB), ... but is a lose battle, the others formats go 10 dBs upper.

But DRC is a help for some situations. The ideal solution is, like I say in precedent post, the player make the function at player time, but waiting for this solution we can use ac3 DRC, not necessarily with DialNorm.

I used this command: eac3to bits0001.thd WoH.ac3

Has the "File size of the raw file doesn't fit" problem been solved yet? I get that problem on 3 different pcs and other than running on Windows XP they dont have anything in common. One has Nero 7.10 installed, the other 7.8.5 so i doubt they both suffer from a bad Nero install. And one doesnt have the mention dtsac3source filter installed so that cant be it either.

Have you tried GraphEdit? You need to rename it to Recode.exe. Then try "Nero File Source /Splitter -> Nero Audio Decoder 2 -> Default DirectSound Device". Does sound play for you that way?

I'm not sure, but probably you need the Blu-Ray/HD DVD plugin? Originally I thought you don't need it for E-AC3 decoding. But right now I guess you do.

@madshi

From what I know, TrueHD in Blu-ray contains DD 5.1 640K core. And, just like DTS-HD, you have to handle sync word emulation very carefully to avoid the incorrect length of extracted AC3. I wrote a tool to extract the DD 5.1 core from Blu-ray TrueHD, and tested on 3 BDs without any problem. I'll send the source code to you so you can merge into eac3to.

Thanks, the source code would be welcome and I'd love to integrate it into eac3to! :)

I think I was careful about the sync word stuff etc. I'm checking for the signature and I'm only accepting frames with a valid CRC. Every AC3 frame should have a valid CRC. Because of that valid AC3 frames should be easy to identify. I think it's more difficult with DTS. There CRC is optional and rarely used, as far as I know. Anyway, I'll compare your source code to mine and check if I can find significant differences... :)

Could you make your DDCore tool available as an exe file? That way "big-guy" could test whether it works better for him than eac3to's solution. I've checked your code and it looks alright to me. But if your code doesn't work better than mine I'd prefer to keep mine.

No, it's different. HD DVD is straight TrueHD with no AC3 in it. In Blu-Ray TrueHD consists of an AC3 track with added TrueHD blocks. The end result is more or less the same. HD DVD needs a bit less space.

eac3to v1.14 released

http://madshi.net/eac3to.zip

(1) DTS dialog normalization can be removed now
(2) DTS core can be extracted from DTS-HD track now

Usage:
eac3to source.dts dest.dts
eac3to can detect if a DTS-HD stream is clean or not. If it's clean, the DTS core extraction should be perfect with no audio sync issues and no crackling sound etc. If the DTS-HD stream is not clean, eac3to will complain, but it will still do the extraction. In this case you need to check if audio is in sync throughout the whole movie.

I've tested the new DTS core extraction on all my HD DVD and Blu-Ray movies with such tracks. The tracks were demuxed by EvoDemux (for HD DVDs) and xport (for Blu-Rays). eac3to reported all tracks to be clean - except the "Perfume" tracks. This problem has been reported before. For whatever reason the "Perfume" DTS-HD tracks demuxed by EvoDemux are corrupt. Well, eac3to detects that, which is good. So, if eac3to doesn't complain you can feel safe that everything is fine.

One important thing to note: The current version of the "DTS/AC3/DD+" filter plays all DTS(-HD) streams from Blu-Ray and HD DVD incorrectly. Basically as soon as you seek, audio sync is lost. I've fixed the problem in the filter and uploaded a new version here:

http://madshi.net/dtsac3source.zip

This is not a unicode build, though, so it might not work with DTS/AC3/DD+ files in folders with "strange" file names. I hope we'll get a unicode build from orbitlee or Casimir later.

Another way to work around the DTS/AC3/DD+ filter problem is to mux the HD DVD and Blu-Ray DTS (core) tracks into a container, e.g. MKV or TS. That way the sync problems with seeking should also disappear.

I think eac3to v1.14 should already do that just fine. It will complain that the track is not clean, but you can ignore that warning in this case. To be sure I'd suggest that you test run the same Surcode DTS track through both BeSliced and eac3to. The end result should be 100% bit identical.

Btw, when using eac3to to automate Surcode the DTS tracks are already padding free.

Thanks for this great software!

I have used it to convert E-AC3 track on Heroes HD-DVD to AC3, but for one of the episodes (Episode 5) eac3to reports that the E-AC3 is not clean and tells me to use delaycut to fix it. However delaycut doesn't seem to support E-AC3.. Or am I mistaken?

EVOs has been demuxed using EVOdemux 0.627 b7.
Ehm yes, you're right. delaycut (sadly) doesn't support E-AC3 yet. What I can offer to you is a switch to either ignore dirty E-AC3 tracks (the E-AC3 audio decoder might eventually stumble then - but probably not) or to remove any dirty audio frames (which may affect audio sync). What do you think?

What do you think?

That would be really cool. It would give the user 3 options with dirty E-AC3 tracks; plain old error like today, possibly a good AC3 track if the decoder is ok with errors or an AC3 track that is out of sync depending on the number of dirty audio frames. If eac3to could print out the number of frames (and possibly timecode) removed in the last case it would help as well, but the most important thing is to have the switch you talk about.

I take it you are talking about possible improvements in new versions of eac3to?

I don't think madshi added any new OPTIONS in the latest version of eac3to. Madshi's updates in v.1.14 are automatically invoked based upon the filename extension(s).
That's correct. It's just that now "dts", "dtshd" and "ac3" are accepted as input formats, if appropriate output formats are used. Also "eac3" etc is accepted as output format, if "eac3" (or similar) is also the input extension.

Once you've installed Nero you open Nero ProductSetup and select Licences panel. Click add and insert your serial to get the plugin to work.

Goodluck !

Question for anyone who knows. I've rebuilt an .EVO containing a single TrueHD track. When I use EAC3TO, the raw file it generates is 0kb. I can do conversions of eac3 -> ac3 all day long no problem. Anyone know the possible problem leading to the raw output failing?

EDIT: I've got the following in my system because I can see the last three in graphedit. The nero filter works because the standard EAC3 -> AC3 conversions work.

(1) Nero HD-DVD/Blu-Ray plugin
(2) "Nero Splitter"
(3) "Nero Audio Decoder 2"

You can set the output Extension to .raw when you want a .raw or to wav (5.1 wave) or .wavs (mono waves).

Or to ac3 /dts
So youve a lot of options :)

When you need 6 mono wave use .wavs output extension.
Then feed your prefered encoder to encode to whatever, for example to WMA10pro or WMA 9.2 lossless.
But note that WMA lossless wont play smooth with WVC1 VBR Peak Video on your Xbox360.

I tried both Eac3to versions 1.14 and 1.13.
I´m not at my home pc right now, but I´m pretty sure the error message looked exactly the same with the aften version that shipped with eac3to.

Hello to all,

First I want to send many thanks to madshi for this great program! :thanks:

I used eac3to with success but I still have a small problem that maybe some of you guys can give me a tip on?

What I am trying to do is import LPCM to Scenarist HDMV (Blu-Ray). What I do is this:

1) I take an eac3 source (DD+) and use eac3to to transform it into ac3 (DD).

2) eac3to goes into it's different stage of treatment and at some point, it generates a big .WAV file (from the .raw file) which contains the 5.1 channels. It is about 6GB.

3) I then open MUI Generator in Scenarist and import the 6GB WAV file into it. It auto detects the file as a LPCM with 6 channels L-R-SL-SR-C + Lfe. So all is super so far.

4) Then I click the "Create files" button so that the MUI Generator c reates the importation stats files but it gives an error saying that the "ChannelAssign" specified does not correspond to the data in the file?

So, in other words, the tool correctly auto-detects the content of the wav files but still gives me an error on the channels assignment. I tried all the other possibilities (8 channel, mono, 1 ch, 4ch, etc.) and it always says this?

What I can think of is maybe there are "names" for each channels embedded in a wav file and the names created by eac3to (probably more by Aften I think) are not compliant so the program does not know which channel is the LFE, which channel is the center, etc.?

Anyone had that problem or can give me a tip that I can try out? Are the channels in a WAV file "named" like I said and if so can I use a program like Audacity to change the names?

Basically, I am trying to make a blu-ray disc with a LPCM soundtrack coming from a DD+ source.

Thanks in advance for any help! :)

First of all Tanks for this application! (seems to be a cool tool)

I tried to use it to convert eac3 traks to ac3.
used v1.13 and v.1.14
I have Nero installed and the bluray pug registered i have also the sonic filters installed but i always get the same result - nothing :(

this is the commandline
The dump filter (from the graphedit pack) is installed (i've registered it again manualy to be sure)

It creates a 2. file named fdolby.ddp (dialognorm removed i guess) and then aborts.

This is a problem with the Dump filter. It is not correctly registered. I had the same problem before I registered it. I know it sounds weird because you said that you registered it but the problem is still that clearly from the log you just typed. Did you move the Dump.ax file after registering it. I think you need to not move it but I am not sure.

From what my friend told me, DRC is evil and pretty much destroy a surround soundtrack. I think he said it makes everything flat. You definitely want to avoid that.

Can someone tell me what dialog normalization is though? From what I could see so far, it seems to be the thing they use on DVDs and now HD-DVDs and Blu-Ray so that the sound is way lower than, for example, a video game sound. I did a test with dialNorm removed and the movie was playing loud on -50dB on my amp and I normally put any movie at -36dB or something like that to have the same volume level. I did a encode with "keepNorm" but I have yet have the time to compare both tracks but on the PC Speakers it seemed like the new encode is lower in volument like I suspected.

Am I right in my understanding of dialNorm? If so, I guess I will keepNorm always because I am used to put the volume high on movies and I may get "surprised" everytime if the volume is too loud on my BD-R projects.

Is there a negative in keeping dialog normalization on? I know DRC is bad but is dialNorm bad for the sound quality or is it just a volume thing?

Thanks for any help.

The WAV file eac3to creates doesn't have any channel assignment information in it. Maybe the MUI Generator doesn't like that. But it's difficult to create wav files that everybody likes, especially once the wav files get bigger than 2GB or even 4GB.

Can the MUI Generator accept raw PCM data instead of a wav file?

eac3to fdolby.eac3 fdolby.ac3 -640 -nero

Thank you for the reply.

I tried the .raw file also in the MUI generator and it did create the stats file but when I tried to import the .ves file in scenarist it said it could not read the file. I think it was "mixed up" and that it does not accept raw. In the doc it says it accepts ".lpcm" and ".wav". I don't think I can import 6 channels separately either from what I saw. It needs to be a single .wav file with correct channel assignment.

How does channel assigment works? Can I edit that in a WAV editor or in a HEX editor?

Thank you.

madshi

5th September 2007, 08:24

In the doc it says it accepts ".lpcm" and ".wav".
"lpcm" is raw data. However, it's usually big endian while eac3to's raw output is usually little endian, IIRC. You could try using sox to convert eac3to's raw output to little endian. Maybe that helps.

It needs a slightly different wav header than the one eac3to is writing. You could try rewriting the file with some wav compatible tools, e.g. wavwizard. Maybe those make eac3to's wav file acceptable for Scenarist.

Excellent tips. I will try the sox thing first and then the other one if it fails. Thanks!

I have another question for you. It seems like eac3to's default bits are 24 bits for the sound right? The first line that appears when eac3to starts, is it the stats of the source file? Because on my eac3 (DD+) it said 24 bits but I am wondering if it is the default value that was said there or if it really is that the source file is 24 bits? I think the source file is 24 bits because it describes the length of the file (2:00:34 for example), the format (DD+), etc.

Yes but it's Scenarist HDMV, not Scenarist SD DVD and when I loaded up my 24 bits WAV file it auto-detected as 24 bits and it seems to be acceptable to Scenarist since it is in the possible pop-up option for LPCM.

Do you know of a way to import all the 6 channels separately to create a 5.1 track in Scenarist HDMV? I will need to check that out then if it is a possibility.

There's no thing like a specific bitdepth for AC3 and E-AC3 tracks. The (E-)AC3 headers don't contain any such information. In the end it's the AC3 decoder which decides which bitdepth it outputs. The Nero audio decoder usually outputs 24bits. eac3to just takes what the E-AC3 decoder outputs.

BluRay LPCM is 16Bit or 32Bit
Wave can be from 8-32Bit

Its a huge difference in Filesize.
But, imho, when you convert LPCM 24bit to 16bit Flac its enough. Its not lossless anymore. You wont hear any big differrence

Ok, I am new at using the eac3to program. I have used evo demux to strip everything out of the first feature evo file for "A Perfect Storm" and now I am left with the video and the single DD+ audio track. I open up Eac3toGui and set up the source file, it automatically sets the output file, and I set the rate to 640kbits, Nero as force filter, and leave everything else at defualt. When I hit convert the black command prompt screen comes up and states the following:

I: Evodemux ARea>"C:\Documents and Settings\Ryan\Desktop\eac3to.exe" "I:\Evodemux ARea\Perfect Storm 1.EVO"
"I:\Evodemux ARea\Perfect Storm1.ac3"-640-nero-24
"C:\Documents and Settings\Ryan\Desktop\eac3to.exe"is not recognized as an internal or external command, iperable program or batch file.
I:\Evodemux ARea>

I have no idea what this means. Does it have something to do with certain filters not being installed? I have the newest version of nero, and have selected "Nero" as the force filter. I don't really understand what the following are, that are needed for the program to work:

Nero File Source/Splitter
Nero Audio Decoder 2
Dump Filter

I did a search of my c: drive and saw that these things are there as .ax extensions (whatever that means). I do not have the Nero HD-DVD/Blu Ray plugin-assumed I would never need it due to the fact that I never watch VC-1 on my PC. I put these VC-1 files on my Tvix 4100 and play them from there.

I guessed that since I own the newest version of Nero, that all the Nero stuff above was in there somewhere. Any help would be greatly appreciated.

For WAV yes. For LPCM no. LPCM contains nothing but the sound samples. There's no "header" or any other information in a LPCM file about how many channels there are or which bitdepth is being used. However, eac3to tries to find out the LPCM bitdepth by analyzing the audio data.

BluRay LPCM is 16Bit or 32Bit
It's 16bit or 24bit.

Eac3toGui is just a wrapper around eac3to. So you need to download eac3to, too, and put both eac3to and eac3toGui into one folder.

I'm not 100% sure but it seems that for E-AC3 decoding you do need the Nero HD-DVD/Blu-Ray plugin.

Please forgive me if this has been asked before.

What happens if the eac3, lpcm or dts has more than 5.1 channels?

Does surcode support dts es? In the surcode log file, at the start of an encode it reports "ES=NO".

Does aften and eac3 support more than 5.1?
LPCM with 7.1 is supported by eac3to. E.g. you can do LPCM -> FLAC with full 7.1. You need to tell eac3to that the LPCM track has 8 channels, though, by activating the "-8" option.

I've not seen any E-AC3 tracks with more than 5.1 yet. As a result I don't know what Nero's audio decoder does with such tracks. Maybe it puts out full 7.1, maybe it only puts out 5.1, maybe it doesn't put out anything. I've no idea. Let's revisit this topic when the first 7.1 E-AC3 track shows up.

Does surcode support dts es? In the surcode log file, at the start of an encode it reports "ES=NO".

No. Surcode can only encode to 16/48 dts 5.1.
DTS Pro Series or DTS HD Master Suite can encode 6.1 ( 24/96 too)

Tranzcode/Azidts/NiscDTSSource cant decode to 7 mono waves from DTS ES 6(+)1 They all decode to 5.1 only. In this Case the BC is blends into BL BR because 6.1 DTS ES is downwards Compatible. So you shouldnt loose any BC Sounds in theory.
Its the the same with DD EX

Possible Methods to decode/record all Channels from DTS ES and DD EX:

To get 7CH mono Waves from DTS ES 6.1 you can decode/record it via ASIO in Sony Vegas
Play the DTS ES 6.1 Discrete in PowerDVD (6.1 Output) and record it through ASIO with Sony Vegas.
It works via graphedit and CyberlinkAudioDecoder too with dts es 6.1 discrete

- Sony Vegas 6.1 Project ,recording all (already)mapped 7 Channels through Creative ASIO Input
http://img251.imageshack.us/img251/4187/sshot4as3.th.png (http://img251.imageshack.us/my.php?image=sshot4as3.png)

Now youve 7 mono Waves. Ofcourse you cant encode Discrete 6.1 AC3.
But you can encode the BC in the Matrix to Dolby Digital EX in Sony Vegas.

Other Method for me is my Audigy2ZS Card. It has a build in Decoder which is capable to decode DD EX and DTS ES 6.1.
Works fine with Nero Showtime (HDDVDPlugin) Playback and Output Setting to SPDIF.
Recording again with Vegas through ASIO like above. So i am able to get 7 mono Waves from 6.1 Sources (DD EX,DTS ES)
I succesfully made some DD EX 5(6).1 reencodes from DTS ES 6.1 and DD EX with this Methods.

Alternative to encode more than 5.1 Discrete Channels is FLAC. I made some 6.1 Discrete encodes with FLAC, works perfect
But these are only Experiments for me. I have 1 5.1 Setup and im still satisfied with 5.1.
6.1 (ore more) Formats are downwards compatible...so its no Problem
Does aften and eac3 support more than 5.1?
No 6.1 Discrete AC3 isnt possible. Only Dolby Digital EX delivers Matrix encoded BC Channel.

I: Evodemux ARea>"C:\Documents and Settings\Ryan\Desktop\eac3to.exe" "I:\Evodemux ARea\Perfect Storm 1.EVO"

"C:\Documents and Settings\Ryan\Desktop\eac3to.exe"is not recognized as an internal or external command, iperable program or batch file.

I did a search of my c: drive and saw that these things are there as .ax extensions (whatever that means). I do not have the Nero HD-DVD/Blu Ray plugin-assumed I would never need it due to the fact that I never watch VC-1 on my PC. I put these VC-1 files on my Tvix 4100 and play them from there.

The error is because the eac3toGUI program cannot find the eac3to.exe program on your system.

Like madshi said, eac3toGUI is only the user interface to facilitate the usage of eac3to. The real eac3to program is named eac3to.exe and needs to be downloaded separately. After you have downloaded eac3to.exe, you can start eac3toGUI and then go to the menu where you can specify where the eac3to.exe application is and point to it so that eac3toGUI knows where to find the application.

Also, you will need Nero HD-DVD/Blu-Ray plugin. eac3to didn't work for me until I got that. Even if you have the full NERO latest version installed, if you did not pay the extra 25$ for the HD-DVD/Blu-Ray plugin it is not "activated" and thus not functional. You need to go to NeroProductSetup on the start menu and then go to "licenses" or something like that and add a serial number to unlock the hd-dvd/blu-ray plugin.

For WAV yes. For LPCM no. LPCM contains nothing but the sound samples. There's no "header" or any other information in a LPCM file about how many channels there are or which bitdepth is being used. However, eac3to tries to find out the LPCM bitdepth by analyzing the audio data.

Ok that's pretty neat. I didn't have time to try the big endian versus little endian thing on the .raw file but I'll try it out when I can. I doubt it will work but who knows until I try. :thanks:

I thought I had everything working but now I have a new problem.

Running a 1.5mbps dts track via spdif to my processor and all is well.

But a 1.5mbps surcode track plays with stuttering, crackling popping sounds. But decoding this and spitting out analog to my processor and all is OK.

Does anyone know why this is?
Was that Surcode file created by eac3to or did you use Surcode yourself? When not being automated by eac3to, Surcode adds some padding to the DTS files. I've no idea if this may be responsible for the problems you're having or not. Maybe it's something else. Could be that your receiver isn't fully DTS compatible. The eac3to created Surcode files all play perfectly fine with my receiver at least.

Run it through Besclied 0.3
Simply start Besliced and Dra&Drop your dts into the Windows and select fix.
The fixed dts should be clean.
Its a "must be" to fix surcode dts !
eac3to should use a own internal fix to fix surcode dts

I never had any Problmes with Surcode dts

Yeah I was using ac3to. I can't understand it. I'm using a Denon 5803 (A1SR) amp/processor which should be fine. It could be my soundcard (RME), but it passes non surcode 1.5mbps dts fine.

I think eac3to does this, but I ran it through besliced just in case, and it didn't help.

Must just be my processor at fault if the computer can decode the surcode dts stream OK. These top of the range thx ultra 2 processors are not all they're cracked up to be.

More trouble for me, this time with FLAC. As soon as I mkvmerge some avc with FLAC, explorer.exe stops responding whenever I go anywhere near the mkv with FLAC.

Ok, I purchased the Nero HD DVD/Blu Ray Plugin and installed it. And under settings in the eac3togui I click on settings and point to where eac3to.exe is located and get the following message in the command prompt screen:

So, I don't know what to do now. It appears that the program started to do something, but immediately quit-I don't know if I have the "dump" filter installed-I don't even know what it is, let alone how to install it. Again, any help would be greatly appreciated. Thank you.

I think you need to download graphedit, and then register the dump.ax.

Maybe there is someone out there who can help me with that:

I have done some backups of my hd-dvds last week and found the following problem.

I converted the ddp-stream to ac3 (or wav) with eac3to. After that i converted the resulting ac3 or wav to aac 5.1 with besweet. All files are perfect as long as the movie is shorter than 124 minutes. If the length of the movie is longer than 124 minutes, besweet converts always only the first 124 minutes and stopped without any error. so i think this could be a problem of eac3to. so far i tried "van helsing", "troja", "riddick", "underworld" and "king kong" (all european versions).

Is there anyone having the same problem? I have read the whole thread here but didn't found any solution, so any help will be greatly appreciated!

p.s.: sorry for my bad german school english ;-)

Thank you very much, that was the final piece of the puzzle it appears. It produced the AC3 audio file. Now, my next quesion, and hopefully my last, how do I put that AC3 audio file back into my Perfect STorm .EVO file?

Does the AC3 file you get from eac3to play with the correct length? If so, it's very unprobable that eac3to is at guilt here. Maybe the aac 5.1 encoder generally doesn't like tracks longer than 124 minutes? I've no idea. Btw, what you're doing is not really optimal. You're decoding E-AC3 which is fine. Then you're reencoding to a lossy codec (AC3). Which is fine if AC3 is your final aim. But if you want to end up with another format you should skip the AC3 step to keep audio quality as high as possible. You should probably ask eac3to to give you a wav file and then convert that wav file to aac by using BeSweet.

Currently I don't know any way to put an external track into an EVO file. What you could do is to mux the EVO + AC3 into either MKV or TS. Muxing into MKV is rather easy, as long as the movie is not H264. Muxing into TS is a bit more complicated but also possible from what I've heard. Personally, I'm currently keeping all audio tracks in separate files. MPC can play these just fine together with the movie EVO file.

How do you do it and with what program? Also, could I use TSremux to put the video file into .ts or .m2ts and then merge the AC3 audio?

MPC (Media Player Classic) automatically loads the external audio files, if you name them just like the movie file. E.g. if the movie file is named "someMovie.evo", name the audio file "someMovie.ac3". You can also add something to the name, e.g. "someMovie - English.ac3". MPC will automatically load such audio files and play them.

What I want to do is play these on my Tvix 4100 media player-I doubt that it would recognize the audio and video (it plays .ts, .m2ts, .mkv, mpeg2, x264 containers). It will not play .evo files or DD+ or Truehd. I can use TSremux to convert the video, but somehow I need to get that audio to play along with the video. Any ideas?

The Dvico people are just now working on adding MKV support. So it might be the easiest way for you to mux your movie + AC3 into MKV. But as I said, remuxing h264 is a bit problematic. As long as your movie is VC-1 there's no problem.

All these files will be VC-1 since they are my HD DVD rips. But what tools do I need to get this to work, and how do I use them if not self-explanatory? I have no experience with command line prompts by the way, but if I knew what the prompts were supposed to be then I could certainly input them. Thanks in advance.
