Real-time DSP basics using Arduino and the Analog Shield SAR codec board

The Arduino micro-controller development platform has received a lot of attention from hobbyist (makers) as well as university engineering programs. The ability to perform simple, yet effective, real-time DSP, is now easily achieved with Arduino and the Analog Shield. The ADC and DAC of the shield allow aliasing and reconstruction issues to be fully explored. Most other audio DSP platforms employ sigma-delta converters, which integrate the ADC...
