NRG Acoustics SG-4: Surround sound

NRG Acoustics SG-4: Surround sound Multi channel audio is a technique for enriching the sound processing top quality of an 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) in contrast to "screen channels" (center, [front] left, and [front] right) coming from only within the listener's frontward arc. Multichannel audio is portrayed by a listener position or sweet spot in which the audio effects are the most effective, and features a constant or forward perspective of the sound area to the listener around this location. The technique improves the perception of sound spatialization by taking advantage of sound localization; a listener's capability to identify the location or origin of a noticed sound in path and range. This typically is achieved through the use of multiple discrete audio channels routed to an array of loudspeakers. There are numerous multichannel audio based formats and techniques, differing in processing and recording methods together with the number and location of additional stations. NRG Acoustics SG-4: Fields of application Though cinema and soundtracks characterize the primary purposes of surround solutions, its scope of use is larger than that as multi channel audio permits creation of an audio-environment for all sorts 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. When it comes to music material for instance, a live performance may use multichannel approaches to the context of an open-air show, of a musical theatre or perhaps transmissions; for a film specific techniques are tailored to cinema, or even to home (e.g. home cinema systems). The narrative space is also a content that can be improved upon through multichannel solutions. This applies mainly to cinema narratives, much like the talk of the characters of a film, but will also be used on plays for theatre, to a meeting, or to integrate voice-based comments in an archeological site or monument. Here is an example, an exhibit could possibly be enhanced with topical ambient sound of water, birds, train or equipment noises. Topical natural sounds may also be used in instructive applications. NRG Acoustics SG-4 - Other sorts of fields of application include gaming units, personal computers along with other platforms. In this applications, the material would typically be synthetic noise generated by the computer system in interaction with its user. Substantial work has also been done using multichannel surround sound for enhanced situation knowledge in military services and public safety applications.
