For FFT, we need all samples (raw samples), so they are copied to a FFT buffer for later use. There is also no time to process the samples and run the audio receiver part at 16kHz, so I chose to split ...

Example of a working Arduino FFT For the competition RoboSub, an Arduino-Due needs to be able to sample and compute a Fast Fourier transform on an incoming ping.

Voice controlled hardware applications are ruling the modern era. Most of the home appliances are expected to be automated through voice. This project illustrates an alter method of voice processing ...
