\begin{synopsis}
\item [csm2lpc] [ --m $M$ ] [ --f $F$ ] [ {\em infile} ] 
\end{synopsis}

\begin{qsection}{DESCRIPTION}
{\em csm2lpc} calculates linear prediction coefficients (LPC) 
from $M$-th order composite sinusoidal modeling (CSM) parameters 
from {\em infile} (or standard input),
sending the result to standard output.

The CSM input format is
\begin{displaymath}
   \omega(1), \dots , \omega\biggl(\frac{M+1}{2}\biggr), m(1), \dots , m\biggl(\frac{M+1}{2}\biggr).
\end{displaymath}
The autocorrelation function $v(l)$ is obtained from the CSM parameters:
\begin{displaymath}
   v(l)=\sum_{i=1}^{\frac{M+1}{2}}m(i)\cos(l\cdot\omega(i)), \qquad l=0,1,\dots,M,
\end{displaymath}
By solving the autocorrelation matrix consists of $v(l)$ using the
Levinson-Durbin algorithm (see \hyperlink{levdur}{levdur}), the corresponding LPC are obtained as
\begin{displaymath}
   K , a(1), \dots , a(M).
\end{displaymath}

\end{qsection}

\begin{options}
	\argm{m}{M}{order of LPC}{25}
	\argm{f}{F}{minimum value of the determinant of the normal matrix}{0}
\end{options}

\begin{qsection}{EXAMPLE}
In the example below, 15-th order CSM coefficients in float format
are read from {\em data.csm}, and then the LPC are written to {\em data.lpc}:
\begin{quote}
\verb! csm2lpc -m 15 data.csm > data.lpc!
\end{quote}
\end{qsection}
