gsm_print  --  GSM 06.10 supplementary function for debug­
       ging


SYNOPSIS

       #include "gsm.h" #include <stdio.h>

       int gsm_print(f, g, frame);
       FILE * f;
       gsm    g;
       gsm_frame frame;


DESCRIPTION

       Gsm is an implementation of  the  final  draft  GSM  06.10
       standard  for full-rate speech transcoding, a lossy speech
       compression algorithm.  The compressed  form  involves  76
       variables  with  different  numbers  of  significant  bits
       packed into 33 bytes.

       If you are interested in investigating the details of this
       coding  scheme,  gsm_print()  can be used to dump the con­
       tents of individual gsm_frames to a file pointer  provided
       by the application.


RETURN VALUE

       gsm_print() returns -1 if the frame is invalid, else 0.


EXAMPLE

       A single frame looks like this:
       LARc:   29  32  20  11  08  05  06  07
       #1:     Nc 0040    bc 0    Mc 1    xmaxc 60
               06 04 00 03 03 06 04 02 02 04 05 04 01
       #2:     Nc 0045    bc 1    Mc 1    xmaxc 48
               03 07 01 03 04 04 07 01 03 02 04 05 03
       #3:     Nc 0091    bc 1    Mc 1    xmaxc 46
               00 03 03 07 01 06 02 04 05 03 03 02 04
       #4:     Nc 0120    bc 0    Mc 1    xmaxc 47
               07 03 06 00 03 03 06 05 00 03 02 07 04
