NAME
     fmtrack - track formant peaks and generate synthesizer  con-
     trol data

SYNOPSIS
     fmtrack (-i item) (-v) file

DESCRIPTION
     fmtrack converts a set of spectral peaks to synthesizer con-
     trol data in which the frequency, amplitude and bandwidth of
     the first four formants are specified every  10ms.   Formant
     tracking proceeds in three passes: Pass 1 does primary reas-
     signment of peaks, Pass 2 picks  up  basic  tracks,  Pass  3
     "creeps" along existing tracks adding to ends.  If a Fx con-
     tour is available in the file, it is used to create  the  Fx
     parameter  in  the SY item, otherwise a monotone of 100Hz is
     inserted.

     Options and their meanings are:

     -I         Identify program and exit.

     -iitem     Select input item.

     -v         Take voicing decision from FX data.  Default: use
                "flag" value in FM data.

INPUT ITEMS
     12.xx      Any raw formant estimates item.

     4.xx       Any Fundamental frequency contour.

OUTPUT ITEMS
     7          Formant tracked synthesizer control data.
