AC3 Normalizer GUI

How often did you had to turn up the volume of your television set / DVD player to hear the audio of your DVD discs, which were created with AC3 files?

This application addresses some of the volume issues with transcoded AC3 files. It is based on a Soopa toolkit, just in a GUI format. Soopa created some batch files, which use AviSynth, Aften and WAVI. The original batch files and article can be found here: http://forum.videohelp.com/topic317891.html

He gave me permission to use the batch files as a basis for this application, and this is the end product.

It is very easy to use. You can either process a group of AC3 files in a specified folder, or drag and drop AC3 files into the application folder for processing. You can select your own bitrate and level of dynamic range compression. If you have VideoLAN installed, then you can play the AC3 files in this application.

Requirements: AviSynth 2.57 or higher

nice thanks!!!

However, your initial warning on start-up about videolan not being installed is not needed, most have ac3filter installed, which will allow anything to play ac3 files. Perhaps a box to say "Do not show this warning again"

at start of script I see

"could not find C:\tmp\*.avs"

Also when using 2.0 ac3 files you loose the right channel upon conversion.

Also, perhaps you should add in a clean up as afen, dlls, etc are left in source folder

nice app

ok....I did some checking.

I can verify that the dlls and afen, etc. are deleted....but only when you exit your program (I had left it open...sorry)

Now as far as 2.0 AC3 is concered, this program will convert to 5.1....perhaps only 5.1 files can be used?

see:

http://forum.videohelp.com/topic317891.html

says only 5.1

if only 5.1 perhaps you should put this in help so people don't get confused (like me LOL).

If you can somehow make it do 2.0, that would be useful too

thanks again!!!!

some users may have some .avs files in their working folder...so perhaps a warning in the help section that they will be deleted may be useful as well.

cool proggy!!!!

Today I downloaded the AC3 Normalizer to level up the volume on an AC3 file I have.

But I'm having some problem on the setup, because apparently my file is 448Kbps, and the program accepts Bitrates only up to 384Kbps.

Also I don't know what Dynamic Range Compression to apply, as I don't know what ratio my file is.

Where can I get such info?
