Hi
Can someone guide me to the right algorithm to average magnitude in fft spectrum. Can this be done with n-point moving average filter without need to store last n frames of magnitude spectrum? Now I’m using exponential moving average algorithm – Xavr = alpha*Xavr + (1-alpha)*Xnew. Is there similar formula for n-point moving average?
Best regards
