<BLOCKQUOTE>Produce a single set of coefficents from a waveform. The type of 
coefficient required is given in the argument &lt;parameter&gt;type&lt;/parameter&gt;. 
Possible types are:

<P>&lt;variablelist&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;lpc&lt;/term&gt;&lt;listitem&gt;linear predictive coding&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;cep&lt;/term&gt;&lt;listitem&gt;cepstrum coding from lpc coefficients&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;melcep&lt;/term&gt;&lt;listitem&gt;Mel scale cepstrum coding via fbank&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;fbank&lt;/term&gt;&lt;listitem&gt;Mel scale log filterbank analysis&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;lsf&lt;/term&gt;&lt;listitem&gt;line spectral frequencies&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;ref&lt;/term&gt;&lt;listitem&gt;Linear prediction reflection coefficients&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;power&lt;/term&gt;&lt;listitem&gt;&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;f0&lt;/term&gt;&lt;listitem&gt;srpd algorithm&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;varlistentry&gt;&lt;term&gt;energy&lt;/term&gt;&lt;listitem&gt;root mean square energy&lt;/listitem&gt;&lt;/varlistentry&gt;

<P>&lt;/variablelist&gt;

<P>The order of the analysis is calculated from the number of
channels in &lt;parameter&gt;fv&lt;/parameter&gt;.  The positions of the analysis
windows must be given by filling in the track's time array.

<P>This function windows the waveform at the intervals given by the track
time array. The length of each window is &lt;parameter&gt;factor&lt;parameter&gt;
the local time shift. The windowing function is giveb by
&lt;parameter&gt;wf&lt;/parameter&gt;.
