AC3 ACM Decompressor 1.31

AC3 ACM Decompressor for VirtualDub The core is based on liba52, and it works with most any ACM client (VirtualDub, TMPGEnc, Avisynth, CoolEdit, etc). The only downside Im aware of is that it tends to override DirectShow AC-3 filters, like Valexs If youve never installed the decompressor before, simply right-click on the AC3ACM.inf file, and choose Install from the popup menu.

I dont think its necessary to reboot, but it cant 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 Panels 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. (Its probably not necessary to do all that, but again, it cant hurt.)

Changes :
- 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).
