NRG Acoustics A-70: Multichannel surround sound
Surround sound is a technique of enhancing the sound processing high-quality of an audio source with additional audio channels from audio speakers that surround the listener (surround channels), providing sound with a 360 radius within the horizontal plane (2D) compared with "screen channels" (center, [front] left, and [front] right) originating only on the listener's forward arc.
Multichannel surround sound is portrayed by a listener location or sweet spot where audio effects work best, and presents a limited or frontward perspective of the sound field with the listener as of this location. The procedure enhances the notion of sound spatialization by manipulating sound localization; a listener's capability to get the location or origin of a detected sound in path and range. Typically this is achieved with the help of multiple discrete audio channels routed to an array of loudspeakers.
There are lots of multichannel based types and methods, ranging in reproduction and recording techniques as well as the amount and the positioning of of additional stations.
NRG Acoustics HJ-17: Fields of application
Though cinema and soundtracks signify the foremost uses of surround techniques, its scope of application is expansive than that as surround sound enables creation of an audio-environment for all sorts of purposes. Multichannel techniques could be used to recreate contents as various as music, speech, synthetic or natural sounds for cinema, television, transmissions, or pc's. Regarding music content for example, an active performance may use multichannel approaches to the context of an open-air concert, of a musical theatre or for broadcasting; for a film specific techniques are tailored to movie theater, or even to home (e.g. home cinema systems).
The narrative place is also a content which may be enhanced through multichannel techniques. This is applicable mainly to cinema narratives, such as the dialog of the characters of a film, but will be also used on plays for theatre, to a meeting, or to blend voice-based comments in an archeological site or monument. Such as, an exhibition could possibly be improved with topical ambient sound of water, wild birds, train or equipment sound. Applicable natural sounds may also be used in informative programs.
NRG Acoustics SG-4 - Alternative fields of application include video gaming consoles, computers along with other platforms.
In these purposes, the material would typically be synthetic noise made by the computer system in interaction with its user. Substantial work has been specifically done using multichannel surround sound for enhanced situation awareness in armed service and general public safety applications.
