Dolby History 

Ever since The Clockwork Orange, the first ever movie directed by Stanley Kubrick came out with a Dolby soundtrack, Dolby Labs has been expanding without the slightest competition or rivalry . The Dolby Labs has achieved the pioneer status in the fields of Sound development, noise reduction, theater experience and what not and yet it is still aiming for something of a higher zenith.

The founder of the company Ray Dolby who earned a Ph.D. in physics started the his own company in 1965. It’s first product was A-type noise reduction for professional market , which diminished the background noise and disturbance form the soundtracks of a video tape without compromising it’s narrative , following that came the B-type noise reduction product for consumer use, then the C-type in course years. The most surreal innovation of the company was Dolby Surround which gave the audience an experience of a sound originating form 4 different sources and directions , the Dolby AC-3 also known as Dolby Digital were being considered for a conventional film’s soundtrack design, which later ungraded to 5.1 channel system( 5 channels and a woofer ) in 2002 and 7.1 channel system( 7 channels and a woofer ) in 2011 .

Dolby Atmos

The latest attraction of the Dolby lab was introduced in 2012 along a Pixar studio animated film ‘Brave‘, known as Dolby Atmos . It is just an upgraded expansion of 7.1 sound system , meaning it envelopes the auditorium at all points even hanging from the ceiling . At most 64 speakers can be used in a Dolby Atmos Cinema resulting mesmerizing sound effects which allows the audience to have  the closest take on a real time sound experience.

What Dolby Atmos system does is properly calibrate sound waves at the right position in the rooms matching the original experience programmed in the soundtrack, surrounding the audience with almost the exact sound experience identical to real environment.Each channels have their individual salient signal. Almost each variation of sound has a designated place in the room.Dolby Atmos features 128 audio tracks plus associated pan metadata for the theaters to dynamically project their feature film with an immense sound. Those 128 tracks signal encoded in a fixed number of channels during post production are transferred to the 64 speakers in the room.
This introduction of the new format has given space to change without bringing compatibility at stake. It monitors the crucial areas of sound production, device handling, sound dubbing for various theaters with significant theatrical format.Hence making the newly introduced format compatible, portable and highly efficient .
