AC-3 ACM Codec
(formerly AC-3 ACM Decompressor) offers Dolby Digital AC-3 decoding for Windows ACM. Install this and you can convert/decompress AC3 audio directly to WAV / MP3 using VirtualDub
, allowing you to use AC3 encoded AVI files, not normally recognized.
How to install/uninstall AC-3 ACM Codec
If you've never installed the decompressor 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 program has not passed "Windows Logo testing" (which is quite true BTW), choose to "Continue Anyway."
To uninstall the decompressor, start Control Panel's "Add/Remove Programs" dialog, select "AC-3 ACM Decompressor", and press the "Add/Remove" button.
If you have installed a previous version of the decompressor, 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.)
