CataRT Standalone

An innovative approach to sound synthesis based on multi-criteria representations of sound sample databases.

The Standalone CataRT Application, a concatenative real-time sound synthesis system, plays grains from a large corpus of segmented and descriptor-analyzed sounds according to proximity to a target position in the descriptor space, controlled by a mouse or by external controllers. This can be seen as a content-based extension to granular synthesis providing direct access to specific sound characteristics. Interaction is made possible via a simple interface featuring a 2D representation descriptor parameter space using mouse navigation where the sound grains (samples) are selected and played as a function of geometrical proximity.

The standalone application has an easy-to-use interface, extensive documentation, complete MIDI and keyboard control, and a preset system allowing interpolation of presets via a MIDI controller.
