CHAPTER 17
DSP Projects
Having seen how you can use the Arduino for signal processing, now you’ll see how you can use the much faster processor in the Due or the Zero in creating sounds and building projects. All these projects were done with the Due, but there is no reason why the Zero can’t be used. Both have enough memory and processing power, along with a built-in A/D and D/A, allowing production of much better audio quality than the Uno is capable of.
There are four projects in this final chapter—using MIDI with the Due, a modeling synthesized plucked string, an audio exciter using transfer functions, and a sound to light show.
