AC3Filter is an open source AC3 decoding filter that allows you to watch videos with AC3-encoded surround audio. After you install the filter, all video players, including Microsoft's Windows Media Player, that use DirectShow, should be able to play AC3 audio correctly. Filter also supports ProLogicII audio as well.
AC3Filter is licensed as Shareware for the Windows operating system / platform from video codec packs and can be used as a free trial until the trial period ends (after an unspecified number of days). The AC3Filter 0.6b demo is available to all software users as a free download with potential restrictions and is not necessarily the download of the full version.
Compatibility with this software may vary, but will generally run fine under Microsoft Windows 10, 8, 8.1, 7, Vista and XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from AC3Filter.
We have tested AC3Filter 0.6b against malware with several different programs. We certify that this program is clean of viruses, malware and trojans. [Read more]
