BNW Acoustics SX-90 Surround sound

Multichannel audio is a technique of enriching the sound processing high quality of any audio source with additional audio channels from audio speakers that surround the listener (surround channels), providing sound from a 360 radius in the horizontal plane (2D) not like "screen channels" (centre, [front] left, and [front] right) originating only from the listener's frontward arc.

Multichannel surround sound is characterized by a listener spot or sweet spot where audio effects perform best, and features a limited or forward perspective of the sound area with the listener at this location. The procedure enhances the notion of sound spatialization by taking advantage of sound localization; a listener's capability to identify the location or origin of a detected sound in path and range. This typically is achieved with the help of multiple discrete audio channels routed to an array of loudspeakers.

There are various multichannel surround sound based models and techniques, ranging in reproduction and recording techniques combined with number and positioning of additional channels.

BNW Acoustics SR-44 Domains of use

Though cinema and soundtracks signify the major purposes of surround solutions, its scope of use is wider than that as multichannel permits creation of an audio-environment for all variations of purposes. Multichannel audio techniques are useful to reproduce contents as varied as music, speech, synthetic or natural sounds for cinema, television, transmissions, or computing devices. With regard to music content for instance, an active performance could use multichannel techniques in the context connected with an open-air event, of an musical theatre or for transmissions; for a film particular techniques are adapted to movie theater, or to residence (e.g. home cinema systems).

The narrative space is also a content that could be improved through multichannel solutions. This applies mainly to cinema narratives, such as the dialog of the characters of a film, but will also be applied to plays for theatre, to a convention, or to blend voice-based comments in an archeological site or monument. As an example ,, an exhibit may very well be improved with topical background sound of water, wild birds, train or machine noises. Applicable natural sounds may also be used in educational applications.

- Several other fields of application contain gaming controllers, computers and other platforms.

In these purposes, the content would typically be fabricated noise generated by the computer equipment in interaction with its user. Significant work has been specifically done using multichannel for enhanced situation knowledge in military services and general public safety purposes.
