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
