Movie showing the use of "Swirls for CataRT" with CataRT version 0.9.9.
"Swirls for CataRT" represents a corpus of sounds, imported, segmented, and analysed by CataRT in a 3D space as shapes of "swirls", a sort of spiralling grass that grows according to the analysed sound descriptors. The swirl space can be navigated interactively with the mouse to trigger playing of the units.
The corpus-based concatenative sound synthesis system CataRT plays grains from a large corpus of segmented and descriptor-analysed sounds according to proximity to a target position in the descriptor space. This can be seen as a content-based extension to granular synthesis providing direct access to specific sound characteristics.
