There are a number of Arduino FFT libraries out FFT (FFT. This is accomplished via the 'exchange' or 'reverse the list' method (ie: if FFT(r,i) is a forward FFT, then FFT(i,r) is an inverse – provided, of course, that the FFT is capable of handling complex inputs/outputs – in other words – no 'real only' routines, which usually presume that imaginary inputs are zero). 0 to do an FFT on the signal from the audio-in jack on a PC.
