It checks an AC3-file for bad frames more>>
either skips it, cuts it down to correct size or repeats the last correct
frame.
This action is determined by the wrongness, i.e. the difference in file size
between the original file and the fixed one. ac3fix tries to make the wrongness
as small as possible.

eac3to 2.02
eac3to is able to convert E-AC3 and TrueHD audio tracks to AC3 or FLAC more>>
TrueHD conversion unfortunately doesnt work with demuxed TrueHD files at this point in time. The to-be-converted TrueHD track must the first (or better: only) audio track in an EVO file. Please use the EvoDemux tool to create one EVO file for a full movie with only the TrueHD audio track in it.
Usage: eac3to src.eac3|evo|wav dst.ac3|flac|raw|wav [-options]
This tool can convert a 2.0 or 5.1 E-AC3 or a 5.1 TrueHD track to AC3/FLAC.
Options:
-192 use 192 kbit/s for AC3 encoding
-448 use 448 kbit/s for AC3 encoding
-640 use 640 kbit/s for AC3 encoding

- Decrease dynamic range to watch movies at night
- Apply time shift to the audio track to synchronize audio with video.
- Adjust gain of every input/output channel independently to compensate loudness differences

AC3 ACM Decompressor 1.4
A very useful AC3 Decompressor for VirtualDub more>>
The core is based on liba52, and it works with most any ACM client (VirtualDub, TMPGEnc, Avisynth, CoolEdit, etc).
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, it is recommended that 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.)
