Multi channel audio
Multichannel audio is a method of enhancing the sound processing top 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) contrary to "screen channels" (middle, [front] left, and [front] right) originating only within the listener's frontward arc.
Multichannel audio is portrayed by a listener location or sweet spot where audio effects work most effectively, and features a fixed or forward perspective of the sound area towards the listener as of this location. The procedure enhances the belief of sound spatialization by exploiting sound localization; a listener's ability to identify the location or origin of a noticed sound in direction and range. This typically is achieved by utilizing multiple discrete audio channels routed to an array of loudspeakers.
There are lots of surround sound based formats and methods, differing in reproduction and recording methods as well as the amount and placement of more channels.
BNW Acoustics ZM-12 Areas of use
Though cinema and soundtracks signify the main uses of surround solutions, its scope of application is wider than that as multi channel audio permits creation of an audio-environment for all sorts of functions. Multichannel audio techniques may be used to reproduce contents as varied as music, speech, natural or synthetic sounds for cinema, television, transmissions, or pc systems. Concerning music content for example, a live performance can make use of multichannel approaches to the context connected with an open-air concert, of an musical theatre or perhaps for broadcasting; for a film particular techniques are adjusted to cinema, or even to home (e.g. home cinema systems).
The narrative space is also a content that could be improved upon through multichannel solutions. This applies mainly to cinema narratives, for example the dialog from the characters of a film, but will be also utilized on plays for theatre, to a convention, or to blend voice-based comments in an archeological site or monument. E . g ., an exhibition may be improved with topical ambient sound of water, birds, train or machine sounds. Applicable natural sounds could also be used in educative applications.
BNW Acoustics Reviews - Additional fields of application incorporate video gaming consoles, computers and other platforms.
In these applications, the content would typically be artificial noise generated by the computer equipment in interaction with its user. Significant work has been specifically done using multichannel audio for enhanced situation knowledge in military and general public safety applications.
BNW Acoustics SX-90
Patch Editor
A computer program allowing the creation or the changing of parameters of sound patches thereby creating or modifying a specific synthesized sound outside of a synthesizer.
BNW Acoustics VS-22 Woofer
1) A speaker that is designed to reproduce bass frequencies only.
2) A drive unit operating in the bass frequencies only. Drive units in two-way systems are not true woofers but are more accurately described as being mid/bass drivers.
3) Part of a speaker system designed to handle the low frequency parts of the signal.
Portamento
1) A pitch change that smoothly glides from one pitch to another.
2) The synthesizer mode or MIDI command that allows or causes this to happen.
BNW Acoustics RS-9 Spaced Pair
Any two microphones spaced to get a stereo pickup especially using the Spaced Omni or Spaced Cardioid techniques.
