Is it possible to get a AC3 file with a bitrate of 448kbps if i change this in mp3_to_ac3.bat?
from:
bepipe.exe --script "import(^upmix1.avs^)" - | aften.exe -acmod 7 -dnorm !char! -v 0 -b 384 - audio.ac3

To:
bepipe.exe --script "import(^upmix1.avs^)" - | aften.exe -acmod 7 -dnorm !char! -v 0 -b 448 - audio.ac3

Or do i get issues on that, or sound distortion?

That should work fine. smile.gif

I'm not happy with the sound of the mp3_to_ac3 script yet. It is OK, but I need to remove the maximizing and limiting which was designed for movie audio and not really music. Better if Chopin isn't IN YO FACE ! laugh.gif

So, go ahead BUT make sure your MP3 files have NO spaces in the name -

Bad: My Music File.mp3

Good: My_Music_file.mp3


I'll fix that in the next version, but until then, that is a limitation.

lol that Chopin is classical music like The Beatles right? listen.gif

Guess that elevator type music would benefit from no normalization at all with perhaps
no/less frequency range cutting to atleast FL FR SL SR and generally a lower avg volume.
I mean you don't want a Triangle to sound like a Symbol due to frequency cuts to rear channels.
And 12th overture for example just has to be louder at the end without peaking 100 fullness dosn't it.

Update to v.06a -

- No More .NET requirements
- Spaces in File Name Support (I think...lemme know if there's a problem)
- Updated Aften encoder to v.07
- Mp3 audio to 5.1 AC3 encoding (and it's pretty fast, too!). File names can now have spaces.
- Upmixed file destination is the "Completed" folder. See instructions in first post.

Spaces, dots and dashes in filenames working fine here.

With a 93 second sample wavi runs at 99% CPU for 2x 5 mins+ using the default Farina script. mix mix mix mix mix mix smile.gif

And only 2x 35 seconds with jagger script.

Yes, but the Avisynth script would require some tweaking using the plugin MT().

http://www.avisynth.org/tsp/MT_07.zip

http://avisynth.org/mediawiki/MT_support_page

It'll take some testing. If you decide to try it, lemme know how it goes.



The Aften encoder can be immediately multithreaded.

Download http://prdownloads.sourceforge.net/win32builds/aften-0.07-win32-bin.zip?download

and replace the aften.exe file in the upmixer folder with the aften.exe found in the zip file above - this folder:





I wish that was the bottleneck. The slow part of this process is the automatic volume level analysis so the new 5.1 AC3 doesn't distort. It works so well, we need to keep it in, even at the expense of the batch processing taking a longer time.


--- Note -- A 1 Hr long AVI took 7 minutes to process on an 8 Core Mac pro, 40 minutes on a 2.4Ghz P4, both running XP

Done a bit more tweaking to allow AVI with AC3 2.0 to be upmixed
with this batch, script and nicaudio.dll AVISynth plugin.

I also knocked that LFE down to standard 120Hz @ Gain 1.5, 480Hz @ 2.0 was still too much.

i try to adjust the output volume LFE to 0.5 because 1.5 is to loud for me.
Its in the Jagger Script.
When i change it in upmix1 and save it with notepad its ok.
But the next day or so its back to its old settings and i have to change it back.

The file you need to modify is UPMIX.AVS


Upmix1 gets modified every time you run the program - that's why it changes. wink.gif


So make your changes to UPMIX.AVS and you'll be good to go

That works..
I did encode a moviefile .
When i play the movie file theres no audio after 3 min 25 ?

I play the original file and the audio sounds ok.

Could that be a problem in the original file and how can i fix that ?

Sorry for my bad english... i live in Belgium and speak normally Dutch.

1) Run your AVI through Avi_Gain_Regular.bat

http://forum.videohelp.com/topic314909.html

2) Play the new Norm-yourfile.avi and see if it plays properly.

3) If it works, use the Norm-yourfile.avi for the 2.0-5.1 Upmix program.

Good luck. If the original file is damaged, it might be difficult to make it work properly.

it did not work...
The extracted mp3 audio looks fine and sound good.
The ac3 file is only 10mb long and stops after 3 min 25

The avi with the new audio sounds good but after converting to 5.1 the audio stops at 3 min 25.

Thanks for the help ...

Those scripts also require the nicaudio.dll AVISynth plugin present in the upmixer folder.

I made a bat file and replaced the other run upmix (from the mp3 upmix) with it.
I placed an nicaudio.dll in the upmixer folder.

It works now ..

Are they scripts available for Action...Adventure movies...
Are there websides where i can find some scripts ?

I tryed your Jagger script... it sounds very good but i adjusted the LFE freq to 90...

It sounds a lot better than for me.....

Greetz to the people downunder......

I was interested in trying to upmix an mp3 music file to ac3 5.1 using your system. First off, it this possible? I am not quite sure what files I need and where to put them.
Thank You

Hi winifreid smile.gif

Look on the first page of this thread for instructions and download info. Change your .MPA extension to .MP3 and run it through Z_Run_mp3_to_ac3.bat . Lemme know if you run into problems. We'll get it working for you.
