Did you ever figure out how to do this? I saw where softencode says it should do it, but I haven't tried yet. You have any luck?

Thanks to a DSP guru tip pointing to a Eye of hours Post (http://forum.doom9.org/showthread.php?s=&threadid=60137&perpage=31&pagenumber=2), I just realized this is possible. Try Sftencdd.exe -help to get the options.

There's a great explanation in this thread http://www.dvdrhelp.com/forum/archive/t161413.html
which I transcript below:


Here's my semi automated solution:

Assumptions
Input file is 48khz wav file. The Program only accepts .wav file input, it's not very good at re-sampling the khz either, SSRC is better suited for that task.

I use three files for my batch setup:

-----------

svcd.ini - Stores settings for use by encoder.

Contents of file:
:

[Parameters]
DataRate=224
SampleRate=0
UseLFE=Off
CodeMode=2
BSMode=0
DlgNorm=-27 dB
DolbySurround=0
CopyRight=On
Original=On
CompressionType=1
Deemphasis=Off
DCFilter=On
BandWidthFilter=On
RFCmpInUse=On



-----------

svcd.bat - Batch file that accepts two paramters, the source wav file name (%1) and the target ac3 file name (%2). This batch file executes the encoder in a silent mode.

Contents of file:
:

Sftencdd.exe -A -P C:\program files\Sonic Foundry Soft Encode\svcd.ini -o %2 -L %1 -R %1 -N



Notes:
Notice that the path/file name value following the -P parameter doesn't have quotes around it. The application will not work properly if quotes surround this parameter.

-A: tells the application to run in a silent command line mode.
-P: and the value following the parameter tells the application to use the settings stored in the specified ini file for some of the encoder options.
-o: and the value following the parameter specifies the name of the output file.
-L: and the value following the parameter specifies the name of the input file for the left channel.
-R: and the value following the parameter specifies the name of the input file for the right channel.
-N: specifies to store the AC-3 file in non-Intel byte order

-----------

batchenc.bat - Batch file used to process several input files at once.
Contents of file:
:

call svcd.bat P:\DVDOut\VIDEO_TS\VTS_01_1.wav P:\DVDOut\VIDEO_TS\VTS_01_1.ac3
call svcd.bat P:\DVDOut\VIDEO_TS\VTS_02_1.wav P:\DVDOut\VIDEO_TS\VTS_02_1.ac3
call svcd.bat P:\DVDOut\VIDEO_TS\VTS_03_1.wav P:\DVDOut\VIDEO_TS\VTS_03_1.ac3
call svcd.bat P:\DVDOut\VIDEO_TS\VTS_04_1.wav P:\DVDOut\VIDEO_TS\VTS_04_1.ac3
call svcd.bat P:\DVDOut\VIDEO_TS\VTS_05_1.wav P:\DVDOut\VIDEO_TS\VTS_05_1.ac3
call svcd.bat P:\DVDOut\VIDEO_TS\VTS_06_1.wav P:\DVDOut\VIDEO_TS\VTS_06_1.ac3



Notes:
Notice that the path/file name for the two parameters don't have quotes around them. The application will not work properly if quotes surround the parameters.


And this is the standard -help output:

please help out a brother. I tried encoding using this exact comandline. My current path is c:\sonic

from here:

Help a brother out here please. I made an ini file with same information. Whenever softencode runs it deletes everything in the ini file and crashes almost immediately. (About 5 seconds or so) resulting in an 884K bunk ac3 file.

If I set the ini file to read only it does not delete the contents, but it still does not work.

here is my commandline

sftencdd.exe -A -P c:\sonic\softenc.ini -o c:\test.ac3 -L g:\tpb\1.wav -R g:\tpb\1.wav

And here is my ini file in c:\sonic

[Parameters]
DataRate=224
SampleRate=0
UseLFE=Off
CodeMode=2
BSMode=0
DlgNorm=-27 dB
DolbySurround=0
CopyRight=On
Original=On
CompressionType=1
Deemphasis=Off
DCFilter=On
BandWidthFilter=On
RFCmpInUse=On

What is wrong here? the encode fails just as soon as it estimates the time remaining.

1.wav is a stereo, 16-bit, 48 000 hz audio file

I process ALOT of wav files for dvd and would very much love to get the batch process working. I read the howto at doom9 here and dvdrhelp.com (the threads linked to each other with the same info) Also note the paths I have in my comand are all correct, this is wher the wav files are.

Maybe the order of the parameters? This one is fine for me...

[Parameters]
DataRate=224
CodeMode=2
BSMode=0
DlgNorm=26
SampleRate=0
UseLFE=Off
Cmix=0
SurMix=0
DolbySurround=0
CopyRight=On
Original=On
RoomType=2
MixLevel=26
Deemphasis=Off
DCFilter=On
BandWidthFilter=On
LFEFilter=Off
Phase90=Off
Cut3dB=Off
CompressiOnType=1
RFCmpInUse=On
NOnIntel=Off

I´m using SoftEncode 1.0 build 19.
My commandline is:
Sftencdd.exe -A -P G:\DVD.ini -o I:\test.ac3 -L I:\test.wav -R I:\test.wav

Source (test.wav) is stereo,16bit,48Khz

DVD.ini:
[Parameters]
DataRate=224
SampleRate=-1
CodeMode=2
BSMode=0
DlgNorm=27
NonIntel=On
UseLFE=Off
Cmix=0
SurMix=0
DolbySurround=0
CopyRight=Off
Original=Off
MixLevel=25
RoomType=2
CompressionType=1
RFCmpInUse=On
Deemphasis=Off
DCFilter=On
BandWidthFilter=On

I tried a lot of changes in .ini file, but I think that the problem is in command line (SoftEncode bug ?).
Then, I splitted this test.wave in 2 files, one file with only left channel and another file with only right channel.
This last test produces:
Sftencdd.exe -A -P G:\DVD.ini -o I:\test.ac3 -L I:\left.wav -R I:\left.wav
-> produces also a mono sound

Sftencdd.exe -A -P G:\DVD.ini -o I:\test.ac3 -L I:\right.wav -R I:\right.wav
-> produces silent

Thanks in advance,

Alexandre

PS. Using Soft Encode in normal way it works perfectly (stereo).

[gircobain]

Shouldn't you feed SoftEncode with 2 mono wav's, one for each stereo channel (i.e., Sftencdd.exe -A -P G:\DVD.ini -o I:\test.ac3 -L I:\left.wav -R I:\right.wav)?

[vmesquita]

SoftEncode has a annoying dying bug, that happens when you cancel a conversion, and it's exactly like you described. To fix it, remove the softencode keys in the registry. You can do that using this simple .reg:

---------------------- cut - start here -----------------------
REGEDIT4

[-HKEY_LOCAL_MACHINE\SOFTWARE\Sonic Foundry\Soft Encode]

[-HKEY_CURRENT_USER\Software\Sonic Foundry\Soft Encode]
------------------------ end here ---------------------------

@gircobain
I made your suggest and... sound only in left channel!
I don´t believe that is necessary to separate channels to produce a ac3 file. Thanks anyway.

@VMesquita
I used this .reg without sucess.
After run it, I needed reinstall Soft Encode and it continues to produce a MONO ac3.
Did I miss something ?

Thanks,

Alexandre
