What is Dolby Digital AC-3 encoding?
Dolby Digital AC-3 is a technology developed by Dolby Laboratories that allows us to store much more CD-quality audio in much less space than traditional CD-audio. Dolby Digital also allows us to present soundtracks in the home that offer a complete surround sound experience, just like at the movie theatre, with left, centre, and right channels, stereo surround channels and a subwoofer. For the viewers without the most advanced surround systems in their homes, Dolby Digital offers the same soundtracks optimized for mono, stereo or Dolby Pro Logic reproduction.
