But "FFT" = "Fast digital Fourier Transform" only is "faster" if there is a great number of sample / frequencies to be handled. (Order n*log(n) instead of n^2.)

If wanting to detect the Power of just a few frequencies in rather short snippets (and hence low exactness), other means might be usable more effectively.
