The latest version of AC3Filter has been released. Version 1.45b seems to have fixed an occasional sound sync/skip issue I had and also the following in the release notes...
- ACM codec is now included into the package
- Tab labels are now translatable
- All languages available so far integrated
- Avoid poEdit '\r' warning when creating a translation file
- Warning messages about dangerous options
- Loud noise was possible after output format switch or SPDIF state change
- Audio skips problem fixed once more
