NRG Acoustics A-70: Multi channel audio

Multi channel audio is a method of enriching the sound processing superior quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound with a 360 radius in the horizontal plane (2D) as opposed to "screen channels" (center, [front] left, and [front] right) coming from only within the listener's frontward arc.

Surround sound is characterized by a listener position or sweet spot where the audio effects work best, and presents a constant or forward perspective of the sound field to the listener at this location. The technique improves the belief 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 by utilizing multiple discrete audio channels routed to an array of loudspeakers.

There are numerous surround sound based formats and techniques, ranging in reproduction and saving options along with the number and placement of additional stations.


NRG Acoustics HJ-17: Domains of application

Though cinema and soundtracks characterize the foremost uses of surround techniques, its scope of application is more expansive than that as multichannel audio enables creation of an audio-environment for all sorts of functions. Multichannel surround sound techniques may be used to reproduce contents as various as music, speech, natural or synthetic sounds for cinema, television, transmissions, or pc systems. With regard to music material for example, an active performance is able to use multichannel approaches to the context associated with an open-air event, of an musical theatre or perhaps for broadcasting; for a film certain techniques are adapted to movie theater, or even to residence (e.g. home cinema systems).

The narrative area is also a content that could be enhanced through multichannel approaches. This applies mainly to cinema narratives, for example, the dialog from the characters of a film, but might be also utilized on plays for theatre, to a meeting, or to incorporate voice-based comments in an archeological site or monument. As an example ,, an exhibition may perhaps be enhanced with topical background sound of water, wild birds, train or equipment sound. Applicable natural sounds can also be used in educational applications.

NRG Acoustics SG-4 - Several other fields of application contain video game systems, personal computers along with other platforms.

In this purposes, the content would typically be fabricated noise generated by the computer gadget in interaction with its user. Substantial work has been specifically done using multichannel audio for enhanced situation knowledge in armed forces and general public safety applications.
