\begin{funcdesc}{rms}{fragment, width}
Return the root-mean-square of the fragment, i.e.
-%begin{latexonly}
-\iftexi
-%end{latexonly}
the square root of the quotient of the sum of all squared sample value,
divided by the sumber of samples.
%begin{latexonly}
-\else
% in eqn: sqrt { sum S sub i sup 2 over n }
\begin{displaymath}
\catcode`_=8
\sqrt{\frac{\sum{{S_{i}}^{2}}}{n}}
\end{displaymath}
-\fi
%end{latexonly}
This is a measure of the power in an audio signal.
