Yet Another Script - 2.0 to 5.1 Upmixer

Hi,
Where can I get my hands on the entire lastest version?

I tried every link in this thread and I keep getting CRC errors when trying to extract the files.

Thanks,
Chris

What does the trazode does ??

[chrishallowell]

Thanks Soopafresh! That one worked.

1 last question...

Can this handle AC3 or WAV input sound files or do they need to be mp3?
If they need to be mp3, then how do I convert wav(or AC3) to mp3?

Right now I have both a stereo AC3 and a stereo WAV. (I used audacity)
Thanks,
Chris

[Soopafresh]

Start with renaming your .WAV file to .MP3 . Dunno if it'll work, but give it a shot. If that doesn't work, load the WAV back into audacity and "export as mp3", 320kbs

The last batch file I posted will do *.wav 2.0 to AC3 5.1.

The BassAudio v1.6 library used in the upmix.avs script dosn't support AC3 2.0 input and always
outputs 5.1 which the script refuses(bug).
My way around this is to use a custom batch and script with nicaudio.dll inplace of bassaudio.dll.

DirectShowSource requires decoders to always be set to 2.0 output to work properly so I'm trying to avoid just having the 1 set of scripts using DirectShowSource.

I have made custom scripts with nicaudio.dll to only handle *.ac3 2.0 to 5.1.
I can modify them for the default directory structure and post them later.

j4gg3rr - make sure you've got the latest version of Nicaudio.dll

Done thanks!!
Anyone wanting to use these scripts for multiple *.ac3 2.0 to *.ac3 5.1 must also have nicaudio.dll located in the Upmixer folder.

Just like the main AVI scripts, this one will finish with the original *.ac3 and upmixed-*.ac3 files in the "completed" folder.

So here is a modified AC3 2.0 to AC3 5.1 Upmix.bat.
Put in the main folder.

@echo off

rem AC3 2.0 - AC3 5.1 Upmixer v0.6


for  %%a in ("*.ac3") do @echo "%%a">mlist.txt & call :process "%%a"
goto end

:process

type mlist.txt | lmod set cfile=[$1] >currfile.bat
call currfile.bat

if exist audio.ac3  del audio.ac3
if exist upmixer\audio.ac3 del upmixer\audio.ac3

for /f %%s in ('TIME /T') do set stime=%%s
@echo. >>upmix_log.txt
@echo %1 Processing Started at %stime% >>upmix_log.txt

copy "%cfile%" audio.ac3 /y
copy audio.ac3 upmixer /y
cd upmixer

cls
@echo.
@echo.
ctext.exe "{0x1B}		Encoding the 5.1 Audio Track...                      {\n}"
ctext.exe "{0x07}.{\n}"
@echo.
@echo.
wavi upmixac3.avs - | aften.exe -acmod 7 -pad 0 -readtoeof 1 -v 0 -b 448 - upmixed_audio.ac3 >nul

cls
@echo.
@echo.
ctext.exe "{0x1B}		Copy, Move and Delete Files...                       {\n}"
ctext.exe "{0x07}.{\n}"
@echo.
@echo.

cd..

copy upmixer\upmixed_audio.ac3
del audio.ac3
del upmixer\audio.ac3
del upmixer\upmixed_audio.ac3
del currfile.bat
del mlist.txt

mmove "%cfile%" completed
ren upmixed_audio.ac3 "upmixed-%cfile%" & mmove "upmixed-%cfile%" completed

for /f %%e in ('TIME /T') do set etime=%%e
@echo %1 Processing Ended at  %etime% >>upmix_log.txt
@echo. >>upmix_log.txt

:end

And the upmixac3.avs script it uses is the same as the one I posted for *.avi with AC3 file upmixing.
Put it in the Upmixer folder.

EDIT:
Just simplified batch to always use %cfile% and remove all %sfile% and slist.txt usage.

EDIT2:
Another small modification to batch file.
1. Delete a temporary audio.ac3 file left in Upmixer folder.
2. Added another message after encoding for Copy Move delete.
3. Put >nul back on end of wavi command line. Is this needed for anything Soopafresh? I can't see any difference with it there or not.

[Aaron187]

Hey Soopafresh can you show me how i can convert .mpg files into .mpg but with 5.1 sound.

the original mpg only has stereo.

Thanks if you can help

[Soopafresh]

What's the audio - Ac3 2.0, MP2, or PCM/WAV ? Post a Gspot screen cap

[Aaron187]

huh? i have no clue.

i have the video and audio in the same file and the file extension is .mpg

[redwudz]

How to post a screen shot: https://forum.videohelp.com/topic271697.html

[Aaron187]

oh thanks i didnt know i could just screenshot the current window with alt

heres an attached picture of Gspot with my .mpg

testing.bmp

[redwudz]

You can also post it directly: ( I converted to JPEG to make it smaller.)



That appears to have MPEG-1 Layer2 audio, fairly common for DVDs, especially in PAL countries. But you do have a NTSC (US, etc.) format.

[Aaron187]

oh cool thanks. but when i try converting it it doesnt work it only works like avi files.

[Soopafresh]

Okay, MP2 format. Check back in a bit...

[Soopafresh]

Here you go. This version will only work with mpa or mp2 audio in Mpeg files.

Same requirements - Avisynth 2.57 or later

See the first post in the thread for instructions. Instead of your output being in AVI format, it'll be Mpeg

[Delta2]

I wonder, doesn't a 2 channel audio sound a little crappy when upmixed to 5.1 channels ? does it worth it ?

[Aaron187]

Wow thanks!

[Soopafresh]

Delta2 - Listen to the examples on the first page.

[Aaron187]

Here you go. This version will only work with mpa or mp2 audio in Mpeg files.

Same requirements - Avisynth 2.57 or later

See the first post in the thread for instructions. Instead of your output being in AVI format, it'll be Mpeg

http://www.savefile.com/files/1033933

I tried it and the output was ac3, with only audio

[Soopafresh]

If you look in the "Completed" folder, there should be an AC3 file, plus there should be an MPG file that has the 5.1 AC3 already multiplexed inside. You can verify it by Gspot analysis.

[Aaron187]

in the completed folder there is only a ac3 file no mpg file

[Soopafresh]

Hmmm... Try shortening the name of your source MPG file. if it is called "My File.mpg", change it to "MyFile.mpg"

I'll check out the script later if that doesn't work. Not to worry, we'll get it working

[Aaron187]

its called Testing.mpg

il try doing it with the name test.mpg though

[Insomniak4700]

Avast is showing a trojan in the download... bug maybe??

[Soopafresh]

Indeed. No trojan that I'm aware of. Which file is it complaining about ?

[Insomniak4700]

wow that was a fast reply
It's complaining about bassaudio.dll
I downloaded an older version I found on doom9.

I was also wondering, I would mostly be using this for 2 channel WAV audio.
do I need to modify anything in the package??

[Aaron187]

its called Testing.mpg

il try doing it with the name test.mpg though

I tried it with test.mpg and it still didn't work.

[Soopafresh]

Aaron - In the main folder, is there a X.demuxed.m2v file ?
