When a Virtual Source in a Room has more than one channel in its format, it will be represented as a single source with ONE unique index. It will be visualised as a group in its assigned channel based speaker arrangement.
In the above screenshot, the red source consists of 5 channels arranged as a DTU 5.0 surround sound configuration. A multichannel cluster can be conveniently positioned and manipulated as a single group which maintains its correct internal spatial positioning relationships but moves in relation to the absolute listener position in the Room (the Dummy Head). The dot at the centre of each cluster, where each virtual ‘channel emitter’ is attached is called the ‘BaryCentric’ focus - In other words, a relative listener position that the virtual source configuration remains focussed on.
These complex spatial positioning algorithms are computed and controlled in realtime using Spat Revolution’s advanced Barycentric and relative direction source parameters. A group that may contain many elements can be transformed, scaled, moved and manipulated in complex ways, through only one set of controls. See section 8 for a breakdown of the Source Parameters
