There are a few technologies available in sound systems these days but one in particular seems to be remembered the most, Dolby Digital. When we go to the movies we are exposed to a pre movie advertisement for this technology with an impressive display of it’s capabilities. The “Dolby Digital Surround Sound” system can be found in nearly all new sound equipment which includes DVD’s and TV’s that are bought from electrical stores, so it is no wonder the average consumer is familiar with the Dolby logo.

Specifically, the term “Dolby Digital” refers to a digitally enhanced encoding system used by many audio devices for sending and receiving sound signals. Dolby is the name of the laboratory that perfected the technology and it is one of the forerunners in the competition for a bigger and better audio experience. There are competitors in the audio industry, but Dolby is the most prominent and widely-used currently.

Having the ability to support several channels the Dolby Digital technology enables the ability to disseminate in mono or stereo quality. Used primarily in digital equipment like CD players, Tv’s and DVD’s and of course the movie theaters there is a variation that is used in the video gaming industry to make that feeling even more realistic.

Dolby Digital was born 50 years ago by a man by the name of Ray Dolby, hence the Dolby Digital name. He wanted to eradicate or reduce the white noise and static that plagued the audio equipment at the time. Clarity of audio was degraded by this static noise so when the solution he found was released it quickly became the standard for record companies and movie theater production.


As a result the Dolby Digital technology was born. Originally it was in a very compressed formatting aimed at the movie theaters. The first time this technology was used en mass was in a movie by the name of “Batman Returns” in 1992. It merged a stereo sound using left and right channels to produce a much more sharp sound. As a result of the success of this initial movie it became the standard way to make movie sound systems.

The original Dolby Digital moves onward, having made it’s mark the technology has and will continue to improve over time. It’s legacy of changing the way moviegoers experience the theater continues with further immersion of sight and sound melding together to enhance the story and helping to create a pleasant and sometimes exciting memory. Having jumped from an elitist movie theater experience to the home was the next logical step. Home theaters have become the “in thing” where surround sound systems blast acoustic sounds in waves that vibrate the bones of the audience, it is no wonder that Dolby Digital is embraced and applauded for it’s contribution to entertainment.
