Abstract

Real-time interactive software can be difficult to construct and debug. Aura is a software platform to facilitate highly interactive systems that combine audio signal processing, sophisticated control, sensors, computer animation, video processing, and graphical user interfaces. Moreover, Aura is open-ended, allowing diverse software components to be interconnected in a real-time framework. A recent assessment of Aura has motivated a redesign of the communication system to support remote procedure call. In addition, the audio signal processing framework has been altered to reduce programming errors. The motivation behind these changes is discussed, and measurements of run-time performance offer some general insights for system designers.
