Parameterized Morphing as a Mapping Technique for Sound Synthesis

We present a novel mapping technique for sound synthesis. The technique extends the familiar concept of morphing to the domain of synthesis parameters. A morph between defined points in the parameter space representing desirable sounds is itself parameterized with high-level controls. The choice of end points of the morph and the extent of the morph are used as input handles to map arbitrary control signals to the synthesis parameters. Additional off-line methods control the interpolation functions and selection of parameter points. We discuss a tool to allow creation, manipulation and usage of such mappings.
