Joining AC3 files

[bex]

I have "once upon a time in america" which is on a double sided single layer DVD I have extracted the m2v and the ac3 from each side. I can make the video one part using DVD2AVI > vfapi > CCE (its re-encodeing now). But what to I use to join the ac3 files or do I need to ?

I found this some where but the question I have is does ac3 not have header information so it will go tits up where they are joined

Joining the several AC3-files together:
Now you should have one Dolby Digital AC3-file for each VOB from the DVD. But we gotta join them together to form one!
To do this, open MS-DOS prompt if you’re using Windows 98, or cmd if you’re using Windows 2000.
In DOS prompt (or cmd), go to the folder where you have your AC3-files. If you’re not familiar with the basic MS-DOS commands, here are those you need:
cd\ (takes you to the root of the current disk)

x: (takes you to a disk, where “x” is the disk’s letter)

cd y (takes you into a folder, where “y” is the folder’s name)


When you’re in the folder where your AC3-files are, “fill in” and type in the below:
copy /b a.ac3+b.ac3+c.ac3+d.ac3+e.ac3 Whatever.ac3
In the above, “a” is the name of the AC3 from the first VOB, “b” is the name of the one from the second, “c” is the one from the third and so on and on! Notice that there is NO “+” between “e.ac3” and “Whatever.ac3”! “Whatever.ac3” is what you want to call the combined AC3-files.
Sooooo: if I had AC3s from 6 VOB files, and I had named them “1.ac3” through “6.ac3” in vStrip, I would type:
copy /b 1.ac3+2.ac3+3.ac3+4.ac3+5.ac3+6.ac3 Audio.ac3
