NAME
     anspect -- calculate and  display  spectra  from  speech  at
     selected times

SYNOPSIS
     anspect (-i item) (-w window) (-a anlabel|-t  time|-T  time-
     file) (-n) (-m) (-p) (-P) file

DESCRIPTION
     anspect is a program to display a cross-section spectrum  of
     a  speech  signal  of a given analysis window size at a give
     time in the signal.  anspect can also plot a number of spec-
     tra  from a file containing a list of times, normalise spec-
     tra and calculate the mean spectrum.

     Options and their meanings are:

     -I         Identify program and exit.

     -iitem     Select input item.

     -wwindow   Specify the  analysis  window  size  in  seconds.
                Default: 0.020s.

     -c         Perform cepstral smoothing on the resulting spec-
                trum.

     -P         Do  not  pre-emphasise  the   signal   prior   to
                analysis.

     -aanlabel  Specify an annotation label that specifies a time
                at which to calculate the spectrum.

     -ttime     Specify the time at which to calculate the  spec-
                trum.

     -Ttimefile Specify a file containing times (one per line) at
                which  to  calculate  a  number  of  spectra.  If
                filename is given as '-', then the times are read
                from the standard input.

     -n         Normalise the spectrum by subtracting the mean dB
                value from each frequency.

     -m         Calculate the mean spectrum when  more  than  one
                spectrum is calculated.

     -p         Send the resulting graph directly to the printer.

     -fmaxfreq  Set maximum frequency for displayed graph.
