Introduction Are you designing a system that involves audio? Maybe an audio product or a product with an audio subsystem? Here are some tips and tricks that may help you. Designing audio systems and debugging audio presents some interesting challenges.  Sound is ruthlessly
It’s generally accepted that, for processing engines, there is a trade-off between efficiency and generality.  The more a chip is geared towards a specific application, the more efficient it’s likely to be (in terms of speed, energy consumption, and cost).  On one end of
While nearly all signal processing applications require some degree of software optimization, some applications require a sophisticated, multi-tiered optimization approach in order to meet their performance goals. To obtain the most efficient code, DSP software must be optimized at four
At the Consumer Electronics Show last month I was struck (not for the first time) by the number of consumer electronics products that rely on digital signal processing—at this point, nearly all of them. In fact, so many of today's products incorporate digital signal processing-based
