AC3 Audio is commonly used in digital TV and for DVD, where it may be called "Dolby Digital."

AC3 Audio, also referred to as "Dolby Digital", is one of the audio formats used in DVDs and is commonly used in Digital Television (certain Digital Video Capture cards may capture Digital TV signals containing AC3 audio).

The AC3 Filter contains a lot more flexibility in the form of Remapping Channels, transcoding and other power-features which may help trouble-shoot troublesome setups. It can even be used to encode non-AC3 audio into AC3 so that it can be passed along to an external receiver over S/PDIF.
