NRG Acoustics SG-4: Surround sound

Multichannel audio is a method of enriching the sound processing top quality of any audio source with additional audio channels from audio speakers that surround the audience (surround channels), providing sound from a 360 radius in the horizontal plane (2D) compared with "screen channels" (middle, [front] left, and [front] right) originating only within the listener's forward arc.

Multichannel audio is characterized by a listener position or sweet spot where audio effects are the most effective, and presents a fixed or forward perspective of the sound area towards the listener as of this location. The technique improves the perception of sound spatialization by manipulating sound localization; a listener's capability to identify the location or origin of a noticed sound in route and range. Typically this is achieved with the use of multiple discrete audio channels routed to an array of loudspeakers.

There are many multichannel surround sound based models and techniques, differing in reproduction and saving techniques together with the amount and placing of additional channels.


NRG Acoustics HJ-17: Grounds of use

Though cinema and soundtracks signify the major purposes of surround solutions, its scope of use is expansive than that as multichannel permits creation of an audio-environment for all sorts of purposes. Multichannel audio techniques is known to recreate contents as various as music, conversation, natural or synthetic sounds for cinema, television, transmissions, or pc systems. With regard to music material as an example, a live performance can make use of multichannel techniques in the context associated with an open-air concert, of an musical theatre or perhaps broadcasting; for a film specific techniques are adapted to cinema, or to residence (e.g. home cinema systems).

The narrative place is also a content that could be enhanced through multichannel techniques. This is applicable mainly to cinema narratives, such as the talk of the characters of a film, but may be also used on plays for theatre, to a meeting, or to integrate voice-based comments in an archeological site or monument. For instance, an exhibition may perhaps be improved with topical ambient sound of water, birds, train or equipment sound. Applicable natural sounds could also be used in instructive programs.

NRG Acoustics A-70 - Additional fields of application incorporate gaming systems, personal computers along with other platforms.

In this purposes, the material would typically be fabricated noise produced by the computer system in interaction with its user. Substantial work has been specifically done using multichannel surround sound for enhanced situation knowledge in army and general population safety purposes.
