9.11 Barycentric

These rotational transformations will only work on a virtual source that consists of more than one emitter in a grouped channel based arrangement. They will also become active, when you shift-select mono sources together to form an ad-hoc group or shift-select mono-sources in combination with grouped channel based sources. The 3 dimensional group rotations are calculated using a ‘barycentric gravity’ method to transform a network of sound sources constrained in a group relationship.

Rotation XYZ

Rotate a group cluster around the XYZ axis of their common barycentric pivot point.


Scale the group cluster, maintaining their barycentre and relative relationships.

Relative Direction

The barycentric transformations will continue to orient their on-axis energy towards the listener position, if the relative direction algorithm is enabled (see section 9.6)
