ABSTRACTAs part of the SOb European project several cartoon models of contact sounds of solid bodies, “hitting”, “bouncing”, “dropping”, “break-ing”, “rolling”, have been developed and implemented as modules (and sub-patches)for free real-timesound software pd 1 . The modelsare accessed through perceptually meaningful parameters and run with low computational load on standard PC hardware.Theunderlying idea of cartoonification, its motivation and background inpsychoacoustic research are sketched first. The main commonsound-coreof most models, a physics-basedalgorithm of impact-interactionwith interacting resonators in modal description, is shortlypresented. The impact module is embedded in patches of higher-level control to model more complex contact scenarios. The structure, useand potential of the resulting sound objects is described.While the results are a possible basis for reactive sonic interfaces in Human-Computer-Interaction,they can as well be exploited formusical purposes.1.
