NRG Acoustics A-70: Surround sound
Multichannel audio is a way of enhancing the sound processing quality of any audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound with a 360 radius within the horizontal plane (2D) in contrast to "screen channels" (middle, [front] left, and [front] right) coming from only on the listener's frontward arc.
Surround sound is portrayed by a listener spot or sweet spot where the audio effects performs best, and offers a fixed or frontward perspective of the sound field to the listener around this location. The technique improves the conception of sound spatialization by manipulating sound localization; a listener's ability to identify the location or origin of a detected sound in path and distance. Typically this is achieved with the help of multiple discrete audio channels routed to an array of loudspeakers.
There are many multichannel surround sound based formats and methods, differing in processing and recording approaches in addition to the number and location of extra channels.
NRG Acoustics HJ-17: Grounds of use
Though cinema and soundtracks signify the foremost uses of surround techniques, its scope of application is more expansive than that as multichannel enables creation of an audio-environment for all variations of purposes. Multichannel techniques could be used to reproduce contents as various as music, speech, natural or synthetic sounds for cinema, television, transmissions, or pcs. With regards to music material to illustrate, an active performance may use multichannel approaches to the context associated with an open-air concert, of a musical theatre or even for transmissions; for a film particular techniques are adapted to cinema, or even to residence (e.g. home cinema systems).
The narrative space is also a content that could be enhanced through multichannel techniques. This is applicable mainly to cinema narratives, as an example the talk of the characters of a film, but may also be utilized on plays for theatre, to a meeting, or to blend voice-based comments in an archeological site or monument. E . g ., an exhibit could very well be enhanced with topical ambient sound of water, wild birds, train or machine sounds. Topical natural sounds could also be used in instructive applications.
NRG Acoustics SG-4 - Other sorts of fields of application include gaming systems, personal computers and other platforms.
In these purposes, the material would typically be synthetic noise made by the computer system in interaction with its user. Significant work has also been done using surround sound for enhanced situation knowledge in armed service and general public safety applications.
