Different hardware configurations and applications suggest different audio system design trade-offs. VisualAudio is focused on embedded processor applications, and currently works with Analog Devices, Inc. SHARC and Blackfin processors. VisualAudio is appropriate for a wide range of applications, including general purpose audio, pro audio, music “stomp” boxes, consumer electronics (such as audio-visual receiver (AVR) systems), and automotive audio systems. This article describes the decisions that were made in the design of VisualAudio and how they are tailored to the embedded processing environment. It contrasts VisualAudio with previous systems created by the authors, particularly Staccato Systems’ “SynthCore,” currently known as Analog Devices’ “SoundMAX.”
