AC-3 ACM Decompressor 1.5

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.)

Changes in AC-3 ACM Decompressor 1.5 :

- I've ported the code to Visual Studio 2005 and added a new (untested) 64-bit build. Installation instructions are in ReadMe.txt.

• AC-3 ACM Decompressor 1.4

- Fixed an A/V sync problem when encoding 44100 Hz AC-3. 

- If you insert AC3ACM into a DirectShow filter graph as an AC-3 encoder, it chooses a default bitrate based on the number of source channels. The default is (96 * nChannels) kBit/s. I've added an option in the driver configuration dialog which allows you to change the default to (64 * nChannels).
