The design and implementation of a PC-based graphic user interface and control engine for an audio processing system is presented. Design considerations are discussed, and a breakdown between PC-based control tasks and real-time signal processing tasks on a dedicated audio processor is provided. The PC controller provides an innovative means to control, memory manage, and download software modules on the audio processor through a real-time nonintrusive interface. There are several possible applications for this PC-based controller, such as in a stand-alone PC-based audio system, an audio processor development tool, and a design reference and documentation tool.:
