Illustration of 5.1-channels. MP3 Surround is an extension of MP3 for multi-channel audio support including 5.1 surround sound. It was developed by Fraunhofer IIS in collaboration with Thomson and Agere Systems, and released in December 2004. [1] [2] [3] MP3 Surround is backward compatible with standard MP3.
In addition, some DVDs have DTS tracks, with most being 5.1 channel mixes (a few releases, however, have 6.1 "matrixed" or even discrete 6.1 tracks). Blu-ray and digital cinema both have eight-channel capability which can be used to provide either 5.1 or 7.1 surround sound . 7.1 is an extension of 5.1 that uses four surround zones: two at the ...
The Datasette is probably the most sophisticated tape-storage method of any microcomputer. [1] Typical compact cassette interfaces of the late 1970s use a small controller in the computer to convert digital data to and from analog audio tones. The interface connects to the cassette deck using normal audio cables like RCA jacks or 3.5mm phone jacks.
In IBM mainframe technology, a channel-to-channel adapter (CTCA) [1] [2] [3] is a device that connects two input/output channels on (usually) two separate computer systems. [4] The adapter allows one computer system to be treated as an input/output device by another. It is used "to link the processing units in a loosely coupled multiprocessing ...
Another type of cassette adapter is the Bluetooth cassette adapter. It has the shape of a standard cassette, but has a built-in audio Bluetooth receiver module, a simple power supply to allow charging and power and a small battery. Usually, they may power on when the cassette player is set on play, and power off when the cassette player is stopped.

DTS Headphone:X is a spatial audio technology, sometimes referred to as DTS Headphone:X "v2.0" or even "v2.0 7.1", [39] if the technology is to be licensed out to companies and not implemented by DTS themselves (through 1st party applications such as DTS Sound Unbound and others), where usually on non-PC devices such as video game consoles can ...
Dolby AC-4 is an audio compression standard supporting multiple audio channels and/or audio objects. Support for 5.1 channel audio is mandatory and additional channels up to 7.1.4 are optional. [38] AC-4 provides a 50% reduction in bit rate over AC-3/Dolby Digital Plus. [38]
