AVR Atmega audio input RMA using FFT Radix-4

audiogetradix4 is a simple library you can use to interface with a ac audio input. It reads data from an ADC pin and returns the RMS value of the input using DFT Radix-4 algorithm. The discrete Fourier transform (DFT) converts a finite list of equally-spaced samples of a function into the list of coefficients of […]
