Analog Devices Enhances Audio Development On Blackfin Processors With VisualAudi

AES Convention, NEW YORK - Recognizing that more complex audio systems pose additional development challenges for audio engineers, Analog Devices, Inc. (NYSE: ADI), is extending award-winning development software to its Blackfin® family of embedded processors. The company is launching VisualAudio® Designer 2.0 and a precision audio module library at the 119th Audio Engineering Society (AES) Convention this week.

The new VisualAudio Designer 2.0 and its audio module library target the needs of a broad spectrum of audio developers looking to develop feature-rich products with fast time to market. These comprehensive tools, which will be available on Blackfin and SHARC® Processors, address every phase of developing embedded audio systems including design, code generation, tuning, and testing. Comparable support was previously available only for ADI’s SHARC line, which has been an audio industry favorite for more than a decade.

The audio-oriented development tools facilitate the use of Blackfin Processors for even broader adoption in this market, having already been designed into products from industry leaders such as Denon, EDIROL, Roku, and Yamaha. Blackfin Processors’ 16/32-bit architecture features control, signal, and multimedia processing in a single core with processing performance that matches or surpasses the competition’s DSP product range — while also providing lower power consumption, better memory efficiency, and lower cost.

The main elements of VisualAudio Designer are a PC-based graphical audio design tool with real-time tuning support, a code generation engine with optimized routing and memory allocation, and out-of-the-box support for Analog Devices’ EZ-KIT Lite® platforms. These capabilities are complemented by a large library of audio of modules (90+) such as mixers, filters, delays, compressors, limiters, and volume controls, plus source code, detailed documentation, and examples.

In addition to providing tools, Analog Devices is seeking audio developers and system integrators wishing to participate in a program created to enable third parties to use the complete VisualAudio application for commercial development. Interested audio developers are invited to visit ADI in Booth #936 at this week’s AES Convention.

More Features in Less Time
VisualAudio Designer provides simple dialogs that guide system setup and configuration. The user then designs a custom post-processing network by dragging and dropping audio modules from a palette onto a design, and wiring them together. Audio module parameters can be configured at a high level using intuitive graphical user interfaces called “inspectors,” and managed using a preset mechanism. The application also provides a well-documented, open API that allows the user to readily create and import custom audio modules in C or assembly language.

Working in conjunction with the separately available VisualDSP++® integrated design and development environment (IDDE), the VisualAudio Designer application generates product-ready code optimized for MIPS and memory usage.

The graphical environment, the predefined, optimized audio modules, and the opportunity for software reuse combine to help developers reduce time to market for high-quality audio products that have important differentiating features.

VisualAudio Designer will support both Blackfin and SHARC Processor architectures, and provides an easy means to perform cross-platform development and evaluation on the two processor families. The initial release is intended for Blackfin ADSP-53x and SHARC ADSP-2126x and 2136x families of processors, including the SHARC Processor ADSP-21369 with integrated SDRAM support.

Earlier this year, the VisualAudio design and development environment — on which VisualAudio Designer is based — was honored with a DesignVision Award from the International Engineering Consortium (IEC).
