VisualAudio Designer™ Release 2.5 for Blackfin® and SHARC® debuts

AES Convention, San Francisco, CA (10/06/2006) - At the Audio Engineering Society (AES) Convention this week, Analog Devices, Inc. (NYSE: ADI) is tuning into the needs of developers creating next-generation audio applications by introducing the Blackfin® Audio Starter Kit. The starter kit offers a complete package of development software and hardware to enable feature-rich products and fast time to market for embedded audio designs that use Blackfin -- in a spectrum of applications such as premium audio players, personal media players, and professional audio effects processors. The kit features the latest release of Analog Devices’ award-winning VisualAudio Designer™ graphical development tool, also available separately for both Blackfin and SHARC® Processors.

“The new Audio Starter Kit joins our Multimedia Starter Kit, introduced this summer, in an expanding suite of development tools for Blackfin,” said Jerry McGuire, general manager, Convergent Platforms and Services Group, Analog Devices, Inc. “The Blackfin Audio Starter Kit with VisualAudio Designer takes care of the fundamentals so engineers can focus on product differentiation. What’s more, it lets developers experience the advantages of Blackfin in the context of their own applications so they can make informed processor selection decisions early in the evaluation process.”

The 16/32-bit architecture of Blackfin combines control, signal, and multimedia processing in a single core with performance that meets or beats the competition’s DSP product range -- and provides better power, cost, and memory efficiency. As a result, Blackfin has gained adoption in audio-intensive applications including digital home entertainment, networked and streaming media, automotive telematics and infotainment, and digital radio and mobile TV.

Blackfin Audio Starter Kit
The Blackfin Audio Starter Kit software includes the Blackfin SDK (Software Development Kit), which is geared to get projects off to a rapid start by supplying audio algorithms, pre-built binary and source code, fully functional applications, and how-to documentation. Algorithms supported by the starter kit under the appropriate licensing conditions include MP3, WMA, AAC, Dolby Digital (AC3), Dolby Pro Logic IIx, Dolby Virtual Speaker, Dolby Headphone, DTS-ES, DTS Neo:6; Ogg Vorbis and Speex codecs; and high-speed Blackfin and PC communication drivers and utilities. Standard Blackfin development hardware is provided as well: EZ-KIT Lite® evaluation kits and EZ-Extender® daughter boards.

Notably, the Blackfin Audio Starter Kit also includes the company’s award-winning VisualDSP++® integrated development and debug environment (IDDE) and award-winning VisualAudio Designer, a graphical development tool that generates product-ready code optimized for MIPS and memory usage.

The Blackfin Audio Starter Kit will be available in December for the ADSP-BF537. Users that already have the ADSP-BF537 EZ-KIT Lite and the USB-LAN EZ-Extender and Audio EZ-Extender daughter boards may download the Blackfin SDK free of charge. Details are available at

VisualAudio Designer 2.5
VisualAudio Designer addresses every step in the typical audio product development cycle, from design through initial tuning, porting to target hardware, final tuning, and automated testing. 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 support for ADI’s EZ-KIT Lite evaluation kit. Source code, detailed documentation, and examples round out its capabilities.

With Release 2.5 of VisualAudio Designer -- also available independently of the starter kit for both ADI’s Blackfin and SHARC Processors -- comes an expanded library of 400+ time-saving audio modules. These range from basics such as mixers, filters, and delays, to specialized algorithms such as decoders, effects, and spectral processing. The audio blocks are highly optimized and make extensive use of processor features such as SIMD (Single Instruction Multiple Data).

Additional improvements introduced in VisualAudio Designer 2.5 include frequency domain and control rate signal types and modules; enhanced support for decoders, encoders, and matrix processors; and an expanded external COM interface.

VisualAudio Designer 2.5 will be available in December. To learn more, visit
