for pcm yes tell eac3to to eac3to audiotruehd audio.pcm and make sure you use the pcm2tsmu if you plan on muxing it or you will get static noise.

for pcm2tsmu check tebasuna51 signature.

I have some seamless branching movies to do that have truehd, will the audio gaps get fixed and will it say in eac3to? I know that seamless branching movies with truehd with gaps can't be fixed so this is the only reason im doing pcm.

Can't i just run the pcm file back through eac3to as a .w64 and not get any static noise?

I have a bug report for eac3to when using seamless branching blurays and .w64 audio extension. eac3to creates a w64 file then it detects the gaps and re writes the w64 file. The first file is 4.5 gigs but after it re-writes the w64 file it is only 465 megs. It seems to only write the gap information up to the first gap then it stops. Using the same file with the dts or pcm file extension creates a file the correct size.

And using .wav output?

If work we can use:

eac3to input.thd output.wav
eac3to output.wav output.w64

With pcm:

eac3to input.thd output.pcm
eac3to output.pcm output.w64

but maybe the .pcm (raw audio data without header) need more parameters:

eac3to output.pcm output.w64 -override -big -6 -16 -48000

if is a 5.1, 16 bitdepth and 48KHz.

Yes it works using a 2 step method but it would be nicer if the w64 file could be created in 1 step.

Work with .wav?

Sorry, I haven't a seamless branching bluray to test

the problem is with .w64 files only now with any others as far as I can tell. But a temp fix is to to convert to pcm then to w64

If wav work is more easy convert wav to w64 beacuse only the header must be changed, the audio data is exact.
Convert pcm to w64 need change the channel mapping and the audio data from big endian to little endian.

Also wav support more channels config and can be traslated to w64 without lose info.

So are you saying movies with out the seamless branching will work just fine converting truehd to wav then wav to w64?

Converting truehd to either pcm, wav, or w64 there isn't any quality loss its bit for bit correct? there all doing the same thing?

So what your saying is converting truehd to wav then wav to w64 just takes less time to convert the file?

tebasuna51

10th June 2009, 17:54

Is better use wav than pcm like intermediate file to obtain a w64 accepted by TsMuxer.

I always convert TrueHD to wav with eac3to and haven't encountered any problems, seamless branching movie or otherwise. The only possible issue is the one that eac3to warns you about - oversized (>2GB) wav files. As you're converting the wav to w64 with eac3to that doesn't matter though as it handles large wavs.

Converting truehd to either pcm, wav, or w64 there isn't any quality loss its bit for bit correct? there all doing the same thing?

Yep. As tebasuna51 said wav is the best bet for an intermediate file in this case (it's just pcm data with a header describing it stuck at the front).

TSmuxer also accepts large .wavs. I tried 7GB wav and it was correctly muxed to .m2ts :) So in fact we don't have to use .w64 for now.

When eac3to outputs wavs all I used to get was sound for the first 15-30 minutes then white noise.

If is correct is a new and undocumented feature. But this is the eac3to thread.

The audio data in wav is ok, maybe your player can't play it.
There are many soft to manage wav files >4GB (encoders, AviSynth, ...)

Hello,

i have a problem with dts-es matrixed files.

If i try to create the waves from the source file with:
X:\temp>eac3to demo.dts c:\temp\demo.wavs

Creating file "c:\temp\demo.SR.wav"...

Everthing works fine.

But i want that 7th channel so i use the -7 cmd to force the extraction.

But i doesn't work:

Eac3to only creates a log file and interrups.

Is it possible to downmix a 2/2 recording (an old quadrophonics with L-R-SL-SR) to stereo?

The -down2 option leaves it as a 4-channel recording.

-7 don't force to extract 7 channel (-7 means the pcm input have 7 channels)

Like you see is a 5.1 and the BackCenter channel is an analog matrix mix in BackLeft and BackRight channels.

There are other kind of DTS-ES with a discrete BackCenter than can be extracted, eac3to inform with this message:
DTS-ES, 6.1 channels, 0:00:22, 16 bits, 1510kbps, 48khz

tebasuna51

14th June 2009, 10:27

Than it is not possible to extract the matrixed backcenter channel?
For what?
You can play the 5.1 and the phantom BackCenter is there.

BTW, you can try to make a stereo with BL,BR and use a dpl decoder to 5.0, the new FL' is the original BL, the new FC' the original BC, and the new FR' the original BR (the news BL', BR' must be empty).

To do this conversion you can use Foobar2000 and the foo_dsp_fsurround.dll (http://www.hydrogenaudio.org/forums/index.php?showtopic=52235) plugin.

Hello!

I'm using eac3to 3.16. I have 7.1 TrueHD audio track. I'm trying to recode it to flac or to wavs, but I get such error:

The track is .ac3 only because it was demuxed by tsmuxer. I have also tried eac3to in two ways: decoding from BD directly and demuxing from BD (thd+ac3) and decoding to flac or wavs. Just the same error.

why have you blanked out your name in 3 out of 4 C:\Users\XXXXX> ?

and yes, I saw it yesterday. With the 'March of the Pengiuns' German version, Kinowelt have added a 13 second trailer to the start of the film. There were 3 playlists all with 00026.mts (from memory). The chapter points are different.

1) 1:22:26 mins long one with the trailer.
2) can't remember
3) 1:22:15 mins long - was clearly the original film without the trailer

However on demuxing either 1) or 3) I always got the longest version.

From Page 1:

I do have Nero 7.0.8.2 and the Blu-ray/HD-DVD plug-in registered.

I can use Nero WaveEditor or Nero Burning ROM to convert a 5.1 AAC file to a 5.1 AC3 file but I can't seem to be able to get eac3to to use the Nero AAC decoder to do the same job. I wonder what I've done wrong. eac3to reports the following:

Of course I can use Sonic but I would love to use Nero inside eac3to. Can someone help? Many thanks.

I'd like to use the Nero decoder, but it doesn't seem to work. <ERROR>

The time difference is playlist 1 has "Columbia Pictures" intro, and 2) has "Sony Pictures Classics".

Also, one other thing I didn't notice last night in tsMuxeR... 00011.m2ts has a slightly different order to the tracks as the rest of the m2ts files in 1). Same goes for 2).

The movie in question is CJ7... I just wasn't sure I was allowed to post titles.

LOL... i posted my initial concern just before bed, I was pretty tired... now that you all know my true identity... I must kill you!!!... Just kidding.

I'm pretty sure I know why, the first m2ts in each playlist is different from the rest of the m2ts' in rest of the movie. I'm pretty sure manually demuxing the rest, excluding the first m2ts will work... I just haven't tried yet.

I get the same results as you using eac3to on CJ7. I'm trying to back it up using BD Rebuilder (movie only). The movie only result would play with PowerDvD but not my Sony standalone (audio, subtitles, but no video).

I am working with CJ7 too. I think the only way to get this going properly is to manually demux, excluding the first m2ts file. Then remux with tsMuxeR, then feed that structure into BD-rebuilder.

Thanks for the responses people.

I've searched through this thread and found conflicting opinions re Surcode as a DTS Encoder.
For example, the 2 below....

One poster states : "Also I wouldnt use Surcodode DTS Encoder. Its a low quality and outdated encoder. And you cant encode dts es 6.1 with Surcode"

While another states : A dts file created from surcode will most definitely sound better than a core ac3 file if the source is the same. Such as a lossless audio track, like true hd. Remember, there is no magic way the studios have to encode an ac3 file. The same could be said of dts. Surcode outputs the same dts file as a studio would(if not very, very, close)

Which of these opinions have most of you found to be the most accurate ?

My goal is to convert/recode a 1536 dts file to a 768 bitrate. I've been using eacto_more gui , Sonic to decode and Surcode to encode, so am curious if this is the best way or is their another simpler one I should be using ? Thanks

I'd listen to a 640 AC3 soundtrack, and compare it to a 768dts. I'd think they'd be about the same, and the 640 would probably be better (done by the dvd mixing company).

OS - Windows 7.
eac3to doesn't see Nero Audio Decoder (Nero 6 or older). But I have Nero 7.11.10.0 and the Blu-ray/HD-DVD plug-in registered.
It works fine on Vista.

Is there any decision for Windows 7?

I'm running Windows 7 x64 RC1 and everything work fine, nero BD/HDDVD plugin, arcsoft, nero aac, surcode...

Are there any known problems when demuxing a 7.1 source track such as a DTS-MA 7.1 into wav files with EAC3TO?

I was looking to decode the MP3 Surround (http://en.wikipedia.org/wiki/MP3_Surround) files from the diatonis web site (http://www.diatonis.com/downloads.html), but I don't know if the process I'm using is correct concerning the channel ordering.

Only the Fraunhofer decoder package can decode MP3 Surround files to actual 5.1-channel PCM Waves, but while the output files have WAVE_FORMAT_EXTENSIBLE headers, the channels aren't defined. Running these Waves through eac3to produces files with the channels defined, but I have no idea if the Fraunhofer decoder reorders the channels or not (I would assume it does, though, if that's needed; however, I'd rather ask and be certain than just assume things).

The wav output from the command line mp3sDecoder.exe have the WAVE_FORMAT_EXTENSIBLE header, but the MaskChannel field have a value of '0' and can be rejected by some audio soft.

I make a test with mp3sEncoder -> mp3sDecoder and the channel order is correct then you can use eac3to to obtain a wav with a correct MaskChannel value:
MaskChannels : 1551 (FL FR FC LF SL SR)

Other correct value for MaskChannel is:
MaskChannels : 63 (FL FR FC LF BL BR)

You need use ArcSoft decoder.

This:
"Using eac3to with ArcSoft decoder there are a problem, the Side and Back channels are interchanged" (http://forum.doom9.org/showthread.php?p=1265484#post1265484)

Was solved with a more recent version of dtsdecoderdll.dll (http://forum.doom9.org/showthread.php?p=1266679#post1266679)

Thanks. So the difference between the two is basically the difference between Dolby 5.1 and DTS 5.1 configurations?

TMT 3 has version 1.1.0.1 of "dtsdecoderdll.dll"
TMT 3.5 has version 1.1.0.10 of "dtsdecoderdll.dll"

have you tried this new versions?

the latest 1.1.0.10 doesn't work with eac3to though. anyway, it's interesting if they fixed the problem with DTS-HD MA tracks reported by eac3to as "7.1 (strange setup)". as you know such tracks are not bit-perfect decoded by old 1.1.0.0 versions of "dtsdecoderdll.dll"

What?
Don't exist difference between Dolby 5.1 and DTS 5.1 or any 5.1 config, is always 3 front channels, 2 surround channels and LFE.
The Surround channels must be at +-120º from Central channel (more or less)

With 7.1 config the order in wav files is: FL FR FC LF BL BR SL SR
and mean:
BL BR = Back Channels at 150º (more or less)
SL SR = Side Channels at 90º (more or less)

Like you can see don't exist (in wav specs) a exact correspondence with Surround channels in 5.1 (120º)
Before XP SP2 the FL FR FC LF BL BR maskchannels was used for 5.1, after the FL FR FC LF SL SR was recommended but the previous one is also accepted.

Nope, I'm not very interested in 7.1 DTS-MA, I only have 5.1 systems and the 'core' DTS (or AC3) is enough for my old ears.

Sorry.

Maybe the new version can decode titles like Black Hawk Down DTS-HD MA 7.1 without the static noise that is introduced when decoded now.
