Peter Batchelor: composer, sound designer


Versatile, configurable spatialisation/re-spatialisation tool (multiple ins/outs)




Orbit is designed to allow the spatial reconfiguration of existing single or multi-channel sound sources to new multi-channel arrangements. It permits, for example, a two-channel signal to be positioned within an eight-channel array, or an eight-channel signal to be positioned within a 30-channel array (or indeed, conversely, to be ‘quick-collapsed’ to stereo).

The patch was originally designed so that source channels would be evenly distributed around, and orbit a fixed point in the centre of the destination configuration, creating a disk (or as much of a disk as permitted by the number of source channels used) around this ‘nucleus’. Later, functionality was added to allow manual movement of the nucleus (along with orbiting channels), control over the distance of the orbiting channels from the nucleus (i.e. disk amplitude), and the ability to reduce the distance between channels around the circumference of their orbit (e.g. reducing the disk to a semi-circular arc which rotates around the nucleus).

The Orbit interface includes controls for these functions, in addition to a graphical representation of the destination configuration (represented by white rings) and source channels/nucleus (coloured rings). This also acts as a control surface, allowing manual control of the positioning of the nucleus.
