10.2 is the

sampling rates, which is a recent trend in digital recording, does not have a significant perceivable effect and that the next frontier in sound engineering is to increase the number of discrete channels to meet human spatial sound perception.[2] As of 2015, several decoding, UHD
, or virtual expansion processors have approached numbers as great or greater than 10.2.

Channel configurations

.0.5 surround sound would add four more channels to the front listening area and only one

Dolby Pro Logic IIz
simulate this with matrixed height channels, which are derived from ambient sounds from the left and right channels.

The ".2" in 10.2 refers to the fact that an additional

Low Frequency Effects
channel is added, not just a second subwoofer, to enhance the sense of envelopment. All bass from the left channels are directed to a left LFE channel while right channel bass is directed to the right LFE channel.

10.2

The 12 channels of 10.2:

10.2 may also augment the LS (left surround) and RS (right surround) channels by two point surround channels that can better manipulate sound—allowing the mixer to shift sounds in a distinct 360° circle around the movie watcher. This would actually make it 12.2

12.2

The only addition with 12.2 from 10.2 are the "point surround" or "diffuse surround" channels. These would be placed at the same angles as the standard surround speakers at +/-120 degrees, but would be diffuse radiators using

dipole speakers. They would emit sound to reflect off the walls before arriving at the listening area.[3]
The 14 discrete channels are:

Setup with point surround channels
  • Five front speakers: Left Wide, Left, Center, Right and Right Wide
  • Five surround channels: Left Surround Diffuse, Left Surround Direct, Back Surround, Right Surround Diffuse and Right Surround Direct
  • Two LFE channels: LFE Left, LFE Right
  • Two Height channels: Left Height, Right Height

The .2 of the 10.2 refers to the addition of a second subwoofer. The system is bass managed such that all the speakers on the left side use the left sub and all the speakers on the right use the right sub. The Center and Back Surround speaker are split among the two subs. The two subs also serve as two discrete LFE (Low Frequency Effects) channels.

Installations

A 10.2 surround sound system was demonstrated at

Audyssey in Los Angeles and at Bjorn's Audio Video in San Antonio, Texas.[5]

New York University claims to have two 10.2 surround sound systems set up in their new $6.5 million music technology complex at

Steinhardt School. One in a recording studio and one in a screening room.[6][7] Products are already being sold to accommodate 10.2 surround systems such as in-wall speaker jacks.[8]

Currently, there is only a standard for 5.1 surround setups. 6.1 and 7.1 have no real standard, and add channels to the rear instead of the front, which can only be conceived as a marketing tool as sonically the front needs more channels[citation needed]. Audyssey has stated that one fear of marketing 10.2 systems will be that ironically quality might be decreased instead of increased. This is because marketers will push to keep prices relatively the same and to do that with four additional speakers and two subwoofers will almost certainly cost quality.[9]

Media

There is currently only one film available which uses this format, a 30-minute short called Seven Swans.[10] The other 10.2 mixes were created by Holman and others at the demonstrations.

There are some receivers that claim to be "10.2 channels" such as the

Pioneer Elite SC-09TX but just have multiple 6, 7, or 8 channel decoders.[11]
