ascii-bs.awk

Reference Implementation of G.711 standard and other voice codecs

#!/bin/awk
# --------------------------------------------------------
# AWK script to produce an ASCII printout of a "bogus"
# G.192-compliant encoded frame. It will take frame 
# sizes from the command line and print the sync header, 
# frame length, and softbits, alternating 1's and 0's.
#
# NOTE: the ascii output can be converted to bynary using 
# the unsupported demo program ascii2bin.c
