g711.rme - Readme for the G.711 module U G S T Read me file for G711 module (01.Feb.2000) ============================================================= COPYRIGHT NOTE: This source code, and all of its derivations, is subject to the "ITU-T General Public License". Please have it read in the distribution disk, or in the ITU-T Recommendation G.191 on "SOFTWARE TOOLS FOR SPEECH AND AUDIO CODING STANDARDS". ============================================================= The UGST G711 module, version 3.01 (31.Jan.2000) needs the following files: g711.c .......... G711 module itself; needs the prototypes in G711.H. g711demo.c ...... Demonstration program for the G711 module; needs the files g711.c and ugstdemo.h in the current directory. ugstdemo.h ...... prototypes and definitions needed by UGST demo programs. g711.h .......... prototypes and definitions needed by the G711 module. As an auxiliary program, there is: shiftbit.c ...... program to shift (with sign extension) to left or right the input file, saving in the output file. You may need this if you speech data file has less than 16 bit resolution and not left-justified. Makefiles: ~~~~~~~~~~ Makefiles have been provided for automatic build-up of the executable program and to process the test files: makefile.unx .... makefile for compiling on an Unix environment makefile.tcc .... makefile for compiling with MSDOS Borland [bt]cc makefile.cl ..... makefile for compiling with MS Visual C compiler makefile.djc .... makefile for compiling with DJGPP MSDOS port of gcc make-vms.com .... DCL for compiling in the VAX/VMS environment Testing: ~~~~~~~~ The provided makefiles can run a portability test on the demo program. They need the archive tst-g711.zip ([pk]zip compatible archive) and [pk]unzip to extract the proper source and reference processed files. The contents of this archive file is: sweep.src ....... THE reference file sweep-r.a ....... reference file: sweep.src encoded by A-law (A lilo) sweep-r.a-a ..... reference file: sweep-r.a decoded by A-law (A loli) sweep-r.rea ..... reference file: sweep.src enc'd *and* decoded by A-law (lili) sweep-r.u ....... reference file: sweep.src enc'd by u-law (u lilo) sweep-r.u-u ..... reference file: sweep-r.u dec'd by u-law (u loli) sweep-r.reu ..... reference file: sweep.src enc'd *and* decoded by u-law (lili) NOTE! These files are in the big-endian (high-byte first) format. Therefore, before using under MSDOS or VAX/VMS, the files need to be byte-swapped. See unsupported program sb in the ../unsup directory. The CRC-32 (unsup utility crc) for each of the test files are given below: File name CRC32-BE CRC32-LE Size ------------------------------------------ sweep-r.a E714C343 74719FE4 131072 sweep-r.a-a 1595D5BA ABCEAA69 131072 sweep-r.rea 1595D5BA ABCEAA69 131072 sweep-r.reu D6812645 63641C01 131072 sweep-r.u E7513B35 CD170E15 131072 sweep-r.u-u D6812645 63641C01 131072 sweep.src 67B11DDE C8BA7682 131072 ------------------------------------------ Notes: - CRC32-BE: CRC-32 for the big endian format (i.e., most non-Intel Unix systems) - CRC32-LE: CRC-32 for the little endian format (Intel CPUs, etc) - Size: file size, in bytes -- <simao@ctd.comsat.com> - 31.Jan.2000
