NAME
     voc8 - slow and simple 8 channel filterbank/vocoder

SYNOPSIS
     voc8 (-i item) file

DESCRIPTION
     voc8 is a straightforward  implementation  of  an  8-channel
     filterbank  analyser  using  two-pole  Butterworth  bandpass
     filters spaced roughly in critical band proportions.  Energy
     smoothing done at 25Hz to give default 50Hz framerate.

     voc8 has built in filters for signals at 10,  11,  12.8,  16
     and  20kHz.   There  is  no limit to the length of the input
     signal.

     Options and their meanings are:

     -I         Identify program and version number.

     -iitem     Select input item.

INPUT ITEMS
     SP   Any speech signal sampled at 10, 11, 12.8, 16 or 20kHz.

OUTPUT ITEMS
     CO         8 channel vocoder energies.
