     ing.   This program has the advantage that it copes with any
     length input signal.

     -I         Identify program and exit.

     -iitem     Select input item number.

     2.xx       Laryngograph waveform sampled  at  10000,  11025,
                12800,  16000,  20000,  22050,  32000,  44100  or
