Interpolator: a two-dimensional graphical interpolation system for the simultaneous control of digital signal processing parameters

摘要

The musical use of real-time digital audio tools implies the need for simultaneous control of a large number of parameters to achieve the desired sonic results. Often it is also necessary to be able to navigate between certain parameter configurations in an easy and intuitive way,rather than to precisely define the evolution of the values for each parameter. Graphical interpolation systems (GIS) provide this level of control by linking multiple parameters to cursor movements within a visual control space. This paper describes Interpolator, a two- dimensional interpolation system for controlling Digital Signal Processing (DSP) parametersin real time.
