User-Defined Mappings for Spatial Sound Synthesis

The presented sound synthesis system allows the individual spatialization of spectral components in real-time, using a sinusoidal modeling approach within 3-dimensional sound reproduction systems. A co-developed, dedicated haptic interface is used to jointly control spectral and spatial attributes of the sound. Within a user study, participants were asked to create an individual mapping between control parameters of the interface and rendering parameters of sound synthesis and spatialization, using a visual programming environment. Resulting mappings of all participants are evaluated, indicating the preference of single control parameters for specific tasks. In comparison with mappings intended by the development team, the results validate certain design decisions and indicate new directions.
