NAME
     Espect - interactive spectral display

SYNOPSIS
     Espect (-I) (-p) (-s starttime|-S startsamp) (-e  endtime|-E
     endsamp)  (-l  lefttime|-L leftsamp) (-r righttime|-R right-
     samp) (-t print_title) (-i item|-g item) (-n) (-12) sfsfile

DESCRIPTION
     Espect is a program to display  spectrum  cross-sections  of
     regions  of  speech  and lx waveforms.  The program displays
     the input waveform at the top of the screen, and a  spectrum
     at the bottom.  A single cursor or two cursors may be placed
     on the waveform, and the spectrum at the cursor  or  between
     the  two cursors is calculated and displayed.  When one cur-
     sor is used, a window of 2ms is calculated; a hamming window
     is always applied to the selected part of the signal.

OPTIONS
     -I         Identify program name and version number.

     -iitem     Specify  input  Speech  or  Lx   Waveform   item.
                Default: last speech item.

     -gitem     Specify input Speech  or  Lx  Waveform  item  for
                spectrographic display.

     -p         Direct output to printer.  The program  does  not
                enter  interactive  mode.   The  screen  image is
                recreated for the printer  using  other  command-
                line options.

     -sstarttime
                Specify  start  time  for  spectrum  in  seconds.
                Default 0.0;

     -Sstartsamp
                Specify start time for spectrum in samples.

     -eendtime  Specify  end  time  for  spectrum   in   seconds.
                Default: end.

     -Eendsamp  Specify end time for spectrum in samples.

     -llefttime Specify time for left cursor in seconds.  Default
                0.0;

     -Lleftsamp Specify time for left cursor in samples.

     -erighttime
                Specify  time  for  right  cursor   in   seconds.
                Default: end.

     -Erightsamp
                Specify time for right cursor in samples.

     -tprint_title
                Specify a title to appear on the printout.  If no
                title  is given then the date and time is printed
                instead.

     -12        Identify 'unmarked' waveforms as 12-bits.

     -n         Specify a narrow band spectrogram.

MAIN MENU
     zoom       Zoom into selected region of the signal.

     up         Zoom out back to previous region of the signal.

     left       Scroll to view the immediately previous time.

     right      Scroll to view the immediately later time.

     top        Display the whole waveform.

     print      Prints display.  Requests a  print  title  before
                printing in background.

     quit       Exits program.

MOUSE COMANDS
  ON WAVEFORM
     left       Positions left cursor.

     middle     Replays waveform between cursors.

     right      Positions right cursor.

  ON SPECTRUM
     any        Calculates  and  draws  spectrum  from   waveform
                between current cursors.
