Not too long ago, we finished an Arduino FFT library, which added frequency spectrum analysis to the list of things you can do with an Arduino. Now you can do that same task in half the time and half the memory usage, thanks to the Fast Hartley Transform (FHT). It’s identical to the FFT, except [...]

Sorry, no cool picture to go along with this. But, we think its pretty cool anyways. We just finished a really fast FFT library for the Arduino platform. This means you can do frequency analysis of your audio data in real time. It can take input from the ADC or from the CodecShield, and output [...]
