That seems a little bit crazy, but each source themselves is a mono source. It makes no sense transmitting a mono source signal in 7.1 or more channels. We want to restore the spatial behavior of the sonic field by those way. But why transmitting the same signal more as one times, only because amplitude and phase differs a little.
Let my describe a more useful, object orientated way:
The spatial sound field in the recording room becomes initiated from direct wave, radiated by the sound source. That wave front will reflected by all surfaces in the recording room. We can imagine those reflections by mirror source model. Behind each reflecting surface such mirror sources occur. Its spatial position dependent from listener position, its signal become modified by the surface reflection factors.
Those mirror sources situated all around the listener, the reflections arrive from all directions. That’s decidedly for spatial impression. Reducing those spatial distribution of the mirror sources upon the horizontal level, moreover upon a few single channels inevitably caused a significantly loss of spatial impression!
More meaningful is the way, transmitting only the pure mono signal of the source in addition to the reflection properties of the recording room. By principle of wave field synthesis the spatial sound filed become synthesizing very accurate from that information’s. The procedure is described by Wikipedia or by the website
www.syntheticwave.de . Such wfs- rendition systems installed in some cinemas currently. I was able to listen sometimes, the spatial impression incomparably more precise as conventionally reproduction. The virtually source has the ability to whisper directly into your ear, in principle is possible go around the virtually source hence. And you are able to change your virtually listining position nearby the artist by your remote, if you want. Its a object and all is synthetic. But sounds more realistic as conventionally procedures, I know. Some plants are installed in cinemas still.
