1.3 Dolby AC-2 and Dolby Digital (AC-3)

Dolby AC-2 combines spectrum-efficient data compression with professional-

quality audio performance. Two-channel modes excel at conveying different

material such as audio and time code or separate language programming.

Despite the low, spectrum-efficient data rate, Dolby Digital yields very high audio

quality and is suitable for the most demanding of professional and consumer

distribution applications. First demonstrated to the film industry in May of 1991,

Dolby Digital audio coding technology has evolved into a very sophisticated and

flexible system for the digital representation of high quality sound. Dual channel

implementations of the Dolby Digital algorithm can be user-configured to operate

in dual mono or joint stereo modes.

Both the Dolby AC-2 and Dolby Digital algorithms are compatible with Dolby

Matrix Surround decoding. A wide range of bit rates and audio coding modes are
