Software - > AC3ACM

This is version 1.2 of an AC-3 ACM Codec for Windows. Basically I've wrapped an Audio Compression Manager interface around the free liba52 library by Aaron Holtzman and Michel Lespinasse, and the ac3enc code by Fabrice Bellard from ffmpeg. This makes it possible to preview, decode, and encode AC-3 audio in VirtualDub (or almost any ACM client).

AC3ACM is released under the GNU General Public License, and you should have received this license as "GPL.txt" in the parent folder of the distribution. I recommend you read it before using the software. I make no guarantee that AC3ACM will work for you, and I won't be held responsible if your computer explodes, and so on...

If you've never installed the codec before, simply right-click on the "AC3ACM.inf" file, and choose "Install" from the popup menu. I don't think it's necessary to reboot, but it can't hurt. If you get a scary warning that the codec has not passed "Windows Logo testing" (which is quite true by the way), choose to "Continue Anyway."

To uninstall the codec, start Control Panel's "Add/Remove Programs" dialog, select "AC-3 ACM Codec", and press the "Add/Remove" button.

If you have installed a previous version of the codec, I recommend you uninstall the old version as described above, and reboot Windows before installing this version. (It's probably not necessary to do all that, but again, it can't hurt.)

AC3ACM was compiled with Visual C++ 6.0 SP5, and tested under Windows 98SE and Windows XP Pro SP1 and SP2. I haven't tested it on other Windows platforms. You can download the full source code at http://fcchandler.home.comcast.net. Future updates of the software will also be available at that site.
