AbstractIt has long been a dream of those involved in audio manipulation to interact directly with a visualization of the target audio. In recent times, the mouse has been giving way to multi-touch interfaces, allowing a more tactile, immediate and intuitive interaction with the audio, and importantly offering more than one point of parametric contact. New modes of manipulation and performance are increasingly possible through a number of systems. This paper will document the trajectory of recent developments in such multi-touch applications, and investigate workflow and its implications via a number of case studies. Further, using a hybrid of emergent software platforms, it will demonstrate a custom interface design that allows the operator to access a visualization of an audio waveform on one or more iPads, and using multi-touch gestural control applied to the waveform, manipulate the sound via processing on a host computer.
