Revision History:

Version 1.4
  • Release Date: Sep 23, 2007
  • 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).
