Dolby Digital

Dolby Digital is the audio compression technology, developed by Dolby Laborateries. The current version of Dolby Digital is "Dolby TrueHD". Before this, there were 5 other versions of Dolby Digital (Dolby Digital Surround EX, EX –, Live, Plus). Except on the HD version, all other versions are lossy (compressed Data Size/data that contains a voice not being heard teling will be discarded).

Originally called Dolby Stereo Digital until 1994. Except for Dolby TrueHD, lossy audio compression. The first use of Dolby Digital to give digital sound in theatres from 35 mm film prints.

Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in the summer of 1992.

Dolby Digital Optical soundtrack recorded on 35 mm release print using sequential data blocks placed between every perforation hole on the side of the sound track of the film. A constant bit rate 320kbit/s used. A CCD scanner projector take video images scanned from this area, and a processor correlates the image field and extract digital data as the AC-3 bitstream. This data is finally translated into a 5.1 channel audio source.

Dolby Atmos

Dolby Atmos here using the "compression" technology. The first to use Dolby Atmos is the "Dolby Theater" in California. They debuted with the premiere of the film entitled "Breave". Dolby sound system is the Atmos is widely used by right Cinema Theater now.

So because the information (frequency) and the type of sound (bass/treble) delivered with individual sound effects then agan thank indoors atmos will be more realistic compared to the 3d sound in General (surround).

For movies with dolby's own atmos is usually done in the studio that makes San Francisco the dolby technology dolby atmos. This technology started to be used on film box office in 2012, that a brave film using this technology first.

There is now a rival of Dolby atmos nih, namely Barco Auro 3D

Barco also cast long in theaters just a difference these 3d Auro Barco uses audio 11.1 but not individual so he just convert audio 5.1/7.1 to 11.1 with additional ceiling speakers that they called VOG voice of god are tophead speakers from the audience.
