Which chain of command should I use in useac3to to extract and convert the core of a DTS-THDMA track?
I use
Code:
-core %_.ac3 -640 -2pass
, but give an error
Code:
Please specify the source and dest files first and then the options.
.

Please put the full log to know the input file (DTS-MA or TrueHD?, audio only or container source?. 5.1 input or 6.1-7.1?, ArcSoft decoder installed or not?).

First dest file (Track Input (if source is a container) and Output format):
%_.ac3

After the parameters, no matter the order:
-640 (not needed because is the default)
-2pass (not needed because is the default if eac3to detect a overflow in first pass)
-core (not recommended if source is lossless)

If source is lossless 6.1 or 7.1 DTS-HD (and you have the ArcSoft decoder, if not -core is the default) or TrueHD is better use:
-down6

the arcsoft decoders work fine in xp sp3...only for version two of total media theater though!!!

try:

If EAC3to says it cannot find Arcsoft Decoders, do the following (try in this order):


1. Add to the PATH envirnonment variable in XP C:\Program Files\Common Files\ArcSoft\Bin

2. Goto C:\Program Files\ArcSoft\TotalMedia Theatre\Codec and open DOS window and enter
regsvr32 ASAudioHD.ax

Or goto Start and then Run and copy:

regsvr32 C:\Program Files\ArcSoft\TotalMedia Theatre\Codec\ASAudioHD.ax hit enter!!!

#2 should work in MOST if not ALL cases.

3. do #2 above for arcdemux.ax, asaudio.ax, asudioeffecthd.ax, and asaudiohd.ax of #2 alone does
not work

4. DTS decoding may only work when you copy MagCore.dll, MagPCMac.dll, MagUIEngine.dll and
MagUIInter.dll from Program Files\Common Files\ArcSoft\Bin\ to eac3to\ (last item to try)



NOTE: In DOS window typing EAC3to -test (or see GUI for Test) will let you see available filters.
Choose "none" as decoder option in EAC3to to decode DTS with Arcsoft Decoders.


You can also unregister all the decoders if you want, then register just the DTS one:

after installing TMT, open up a command prompt, cd to the directory that contains the filters and run:

for /F %i in ('dir /B') do@regsvr32 /u /s %i

you then just regsvr32 the ax/dll's you need for DTS decoding.

The names of the dlls are pretty obvious.

If the file is already extracted like:

DTS, 5.1 channels, 2:00:24, 24 bits, 1510kbps, 48khz

you only need:
%_.ac3

I've found this working solution:
1. Copy the next files from an ArcSoft Total Media Theatre 3.0.1.170 Platinum Retail installation to eac3to folder:
ASAudioHD.ax
DtsDec.dll
dtsdecoderdll.dll
MagCore.dll
MagPCMac.dll
MagUIEngine.dll
MagUIInter.dll
2. Copy checkactivate.dll from a Total Media Theatre 2 trial version installation to eac3to folder
3. Register ASAudioHD.ax

I've notice that in this case eac3to encode in a single pass.

I've demuxed a pcm audio track from a blu-ray, using tsmuxer. This ended with 2 wav files (3.99 and 2.69 GB). What command line should I use in useac3to to encode to dts ? Or things is much more complicated ?
Thanks.

The WAVs extracted with tsmuxer are broken, use eac3to instead.

Drag & Drop the folder with BRip over UsEac3to, select feature (if more than 1), select track and ac3 output (with -down6 and/or -resampleTo48000 if necessary)

If you want encode to DTS (not recommended) you can select 'wavs' output to obtain 6 monowavs and encode to DTS with a external encoder.

The blu-ray has already an ac3 @640 kbps audio stream.
Your concern is about quality of pcm->dts encoding or about the size of the audio stream ? Already read that ac3 @640 kbps is almost good as dts @1536 kbps, but I'm not sure. What is your opinion ?

Less size, more compatible, and maybe more or at least equal quality.

To distinguish between PCM-source and the DTS-1536/AC3-640 encodes you need:
1) A room acoustic condioned.
2) A very good audio equipament (receiver and speakers).
3) Good ears.

I haven't that room, my audio equipment is not so good (~1000€) and my ears are very old.
Someone say than the AC3-640 is more close to PCM-source than DTS-1536.
I don't know for me is the same.

I've been meaning to ask...

Can your application be used to split the "core" and "HD" audio streams into separate streams?

1: h264/AVC, 1080i60 /1.001 (16:9)
2: DTS Master Audio, 7.1 channels, 24 bits, 96khz
   (core: DTS, 5.1 channels, 24 bits, 1509kbps, 48khz)
Select 'Track Input': 2: DTS, 'Output format': dts, 'Add'
Select 'Frequent parameters': core, 'Add'

Now the command line is:
2: %_2.dts -core
Press 'RUN Command line' and you have the dts core, with:
2: %_2.dtshd
you have the full DTSMA

If the Bluray source have a TrueHD track (3)
3: %_3.ac3 extract the included ac3 track
3: %_3.thd extract only the thd part
3: %_3.tdh+ac3 extract the full track

Thanks for that...

Is it possible to extract the DTS HD audio stream without the core?


Cheers

Yes, I understand that the "core" is mandatory for use with the Blu-ray disc format.

But does this also mean the inclusion of the core is mandatory for DTS-HD MA and DTS-HD HR streams as an audio format?

If this is the case, I guess I'll need a method of transcoding the DTS-HD element to say, PCM or FLAC

Yes, the HD part is a complement to core part.
You need the ArcSoft DTS-HD decoder http://forum.doom9.org/showthread.ph...77#post1398577
