NAME

       gsm_print — GSM 06.10 supplementary function for debugging

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 contents 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
