GSM_PRINT(3) Library Functions Manual GSM_PRINT(3) 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 com- pressed 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 BUGS Please direct bug reports to jutta@pobox.com and cabo@tzi.org.
