NRG Acoustics SG-4: Surround sound

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

Multichannel audio is portrayed by a listener position or sweet spot where audio effects are the most effective, and offers a fixed or forward perspective of the sound area towards the listener as of this location. The technique enhances the notion of sound spatialization by manipulating sound localization; a listener's ability to get the location or origin of a detected sound in route and distance. This typically is achieved with the help of multiple discrete audio channels routed to an array of loudspeakers.

There are various multi channel audio based types and techniques, varying in reproduction and saving techniques along with the number and placing more channels.


NRG Acoustics HJ-17: Fields of use

Though cinema and soundtracks represent the major uses of surround approaches, its scope of application is larger than that as surround sound enables creation of an audio-environment for all variations of purposes. Multichannel surround sound techniques may be used to recreate contents as varied as music, conversation, natural or synthetic sounds for cinema, television, broadcasting, or pc systems. Relating to music content one example is, an active performance can make use of multichannel approaches to the context connected with an open-air concert, of an musical theatre or even for broadcasting; for a film specific techniques are tailored to movie theatre, or to residence (e.g. home cinema systems).

The narrative space is also a content which could be enhanced through multichannel techniques. This applies mainly to cinema narratives, for example, the dialog from the characters of a film, but might even be utilized on plays for theatre, to a conference, or to integrate voice-based comments in an archeological site or monument. Such as, an exhibit might well be improved with topical ambient sound of water, birds, train or equipment sound. Applicable natural sounds can also be used in educative programs.

NRG Acoustics A-70 - Several other fields of application include gaming controllers, computers along with other platforms.

In these applications, the content would typically be artificial noise maded by the computer device in interaction with its user. Substantial work has been specifically done using multichannel for enhanced situation awareness in government and public safety applications.

Multichannel audio is a method of enriching the sound processing high-quality of an audio source with additional audio channels from speakers that surround the audience (surround channels), providing sound from the 360 radius in the horizontal plane (2D) contrary to "screen channels" (centre, [front] left, and [front] right) originating only from the listener's frontward arc.

Multichannel audio is characterized by a listener spot or sweet spot in which the audio effects are the most effective, and presents a fixed or forward perspective of the sound field towards listener as of this location. The procedure improves the notion of sound spatialization by exploiting sound localization; a listener's capability to get the location or origin of a noticed sound in route and distance. Typically this is achieved with the use of multiple discrete audio channels routed to an array of loudspeakers.

There are lots of multichannel audio based formats and methods, differing in processing and saving tactics along with the number and placing more stations.


NRG Acoustics SG-4: Grounds of use

Though cinema and soundtracks characterize the main purposes of surround approaches, its scope of use is larger than that as surround sound enables creation of an audio-environment for all sorts of functions. Multi channel audio techniques are useful to reproduce contents as various as music, speech, natural or synthetic sounds for cinema, television, transmissions, or pc systems. With regards to music content to illustrate, a live performance may also use multichannel techniques in the context of an open-air show, of a musical theatre or perhaps for broadcasting; for a film specific techniques are adapted to movie theater, or even to home (e.g. home cinema systems).

The narrative space is also a content which could be improved through multichannel solutions. This is applicable mainly to cinema narratives, such as the speech from the characters of a film, but will also be utilized on plays for theatre, to a convention, or to incorporate voice-based comments in an archeological site or monument. By way of example, an exhibition might be enhanced with topical background sound of water, wild birds, train or machine noises. Applicable natural sounds could also be used in instructive programs.

In this applications, the material would typically be fabricated noise maded by the computer system in interaction with its user. Significant work has also been done using multichannel for enhanced situation knowledge in government and public safety applications.
