surround sound


Multichannel auio denominates the techniques for enriching (expanding and deepening) the sound reproduction quality, of a recorded source, with additional, recorded sound channels reproduced via additional, discrete speakers. The three-dimensional (3D) sphere of human hearing can be virtually achieved with audio channels above and below the listener. To that end, the multichannel surround sound application encircles the audience (left-surround, right-surround, back-surround), as opposed to "screen channels" (center, [front] left, and [front] right), i.e. ca. 360° horizontal plane, 2D).
