Danville Signal - Your Partner for SHARC-based DSP Boards, Hardware and Systems

Audio Weaver is a software tool created by DSP Concepts that speeds up product development. It provides a large library of optimized software modules that are easily combined to create production quality applications on Sharc and Blackfin based hardware platforms.

Danville Signal is partnering with DSP Concepts to provide Audio Weaver support for many of our boards and systems. This includes complete turnkey systems that allow you to quickly customize your product without the need for VisualDSP++, emulators and specific DSP software and hardware expertise.

For example, a speaker manufacturer can implement a digital crossover with bandsplitting, time alignment, equalization and limiting without writing a single line of code. Parameters are adjustable in real time. When everything is ready, the program is written to flash.

Here's an example of the controls of a simple automatic gain control. You can adjust all the parameters dynamically. It's not a simulation, the actual code executes on the target hardware and the PC interacts with the DSP over a communications link.

Turnkey solutions are just one way that Audio Weaver allows our customers to take advantage of quick time-to-market solutions. You can create your own custom system solutions using Audio Weaver Designer or Audio Weaver Developer.

Audio Weaver Designer allows you to combine Audio Weavers' prebuilt software modules using Matlab. Audio Weaver includes a large library of audio specific processing functions. The audio functions include compressors, limiters, volume controls, tone controls, reverb algorithms, mixers, etc. and are sufficient to construct most audio products. The audio functions have associated control functions enabling them to be manipulated in the final product.

Here's a graphical representation of the same simple automatic gain control illustrated above. The actual code that constructed the system is a short Matlab script.

Audio Weaver Designer runs on any of our supported platforms. Want to give it a try? Our Audio Weaver Demo Package includes Audio Weaver Designer and a companion PCB with 2 audio input channels, 4 audio output channels and a S/PDIF digital audio interface, powered by an Analog Devices ADSP-21371 SHARC. All you need is a PC running Windows XP or Vista and a USB port. 

If you want to create your own target platform or custom modules, check out Audio Weaver Developer, DSP Concepts full featured environment.
