Description AC3 is an audio file specifically developed by Dolby Digital to provide surround sound audio. The format is used for audio on many DVD and Blu-Ray media.

It became the de facto standard for surround sound, and has held that position since its inception in 1992, with it coming to home cinema in 1995.
