Multi channel audio
Surround sound is a way of enriching the sound reproduction superior quality of an audio source with additional audio channels from speakers that surround the audience (surround channels), providing sound with a 360 radius in the horizontal plane (2D) not like "screen channels" (centre, [front] left, and [front] right) coming from only from the listener's frontward arc.
Multichannel surround sound is characterized by a listener spot or sweet spot in which the audio effects perform the best, and provides a constant or frontward perspective of the sound area with the listener as of this location. The procedure enhances the conception of sound spatialization by manipulating sound localization; a listener's capability to know the location or origin of a noticed sound in path and distance. This typically is achieved with the use of multiple discrete audio channels routed to an array of loudspeakers.
There are various multichannel based formats and methods, varying in processing and saving tactics along with the amount and location of additional stations.
BNW Acoustics RS-9 Fields of application
Though cinema and soundtracks characterize the major purposes of surround solutions, its scope of use is more expansive than that as multichannel surround sound enables creation of an audio-environment for all sorts of functions. Multichannel audio techniques could be used to recreate contents as various as music, conversation, natural or synthetic sounds for cinema, television, broadcasting, or portable computers. Relating to music content as an illustration, an active performance can make use of multichannel techniques in the context connected with an open-air concert, of a musical theatre or perhaps transmissions; for a film certain techniques are tailored to cinema, or to residence (e.g. home cinema systems).
The narrative place is also a content which may be enhanced through multichannel solutions. This applies mainly to cinema narratives, for example the dialog of the characters of a film, but might be also applied to plays for theatre, to a convention, or to integrate voice-based comments in an archeological site or monument. For instance, an exhibit might be enhanced with topical background sound of water, birds, train or machine sound. Applicable natural sounds can also be used in educational applications.
- Some other fields of application contain gaming consoles, personal computers and other platforms.
In this 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 audio for enhanced situation knowledge in military and general population safety applications.
