This paper provides an overview of VisualAudio®, a graphical development environment from Analog Devices, Inc. (ADI) that is specifically aimed at audio development engineers. VisualAudio provides many of the software building blocks, together with an intuitive graphical interface, for designing, configuring, and tuning 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."
The sampling-rate conversion algorithm described in this paper provides a computationally efficient method of performing multi-channel asynchronous conversion in software on a modern digital signal processor. This algorithm is integrated into some of the VisualAudio reference frameworks or available stand-alone for both SHARC and Blackfin processors.
