RMS 

The function RMS returns the root mean square for all frequencies in the interval [FirstIx..LastIx ]. RMS is the square root of the sum of all lines of the power spectrum in the specified interval. The indices FirstIx and LastIx may assume values between 0 and SpectrumSize div 2. Accessing any value of the array below 0 and above SpectrumSize div 2 will result in a zero value.
