U.S. Department of Defense LPC-10 2400 bps Voice Coder Release 1.5 October 1997 (Note that this release 1.5 is not from any "official" source. It is from Andy Fingerhut. Contact information below.) This package is available from: http://www.arl.wustl.edu/~jaf/lpc/lpc10-1.5.tar.gz New in release 1.5: Just some minor fixes to sample applications "nuke" and "unnuke" that caused them not to work correctly on compilers with 16 bit int's. This was only a bug in the sample application code, not in the LPC-10 library itself. NEW IN RELEASE 1.4! You can now compress (or decompress) multiple audio streams "simultaneously", by alternating the compression (or decompression) of frames for each audio stream. Only the C version supports this feature, but who really cared whether the Fortran version supported this or not, eh? Contents: README - This file README-1.0 - The original README file from Release 1.0 FAQ - Frequently Asked Questions items for LPC and CELP lpc55 - modified Fortran code for LPC-10 Version 55 README - summary of modifications made README.f2c - hints on installing f2c on some machines, and notes on the f2c invocation options used README.jaf - hints on using the LPC-10 coder from a C application RCS - Revision Control System directory containing master files for all sources, showing the steps of changes that I made to the original 1.0 sources. lpc55-C - Hand-modified C version of code, most of which was created by running f2c on the Fortran code in directory lpc55 above. I'm fairly certain that the C code from the 1.0 release was out of date with respect to the Fortran code, so it was not included in this distribution. data - Sample speech files, containing: dam9.spd - Sample input speech file dam9-out.spd - Speech processed by modified Fortran code. This is identical to dam9_lpc55.spd from release 1.0, except for 180 0 samples at the beginning, and many samples here and there that are off by 1, probably due to different rounding of reals. abtool_1.2 - Sun GUI tool for playing listening comparisons between speech files (this is a beta version) misc bin - Several useful shell scripts for audio on Sun machines README - Description of audio file formats fortran-locals - Some files I made when determining whether local variables in Fortran subroutines and functions were like C "static" local variables or not. gcc-2.6.0-bug - A program that demonstrates a bug in GCC 2.6.0 on the Solaris 2.4 machine siesta.cs.wustl.edu. I don't know how widespread this problem is, but it does have an unpleasant side effect if GCC 2.6.0 is used to compile f2c. See also the file README-1.0 for some other useful details.
