U.S. Department of Defense LPC-10 2400 bps Voice Coder Release 1.0 October 1993 Contents: README - This file FAQ - Frequently Asked Questions items for LPC and CELP lpc55 - Fortran code for LPC-10 Version 55 lpc55-C - C code for LPC-10 data - Sample speech files, containing: dam9.spd - Sample input speech file dam9_lpc55.spd - Speech processed by LPC-10 abtool_1.2 - Sun GUI tool for playing listening comparisons between speech files (this is a beta version) The distribution file has been compressed with the GNU compression program gzip version 1.2.3, available from archives such as ftp.uu.net and wuarchive.wustl.edu. To unpack it, use the commands: gunzip lpc-1.0.tar (uncompress the archive file) tar xvf lpc-1.0.tar (extract the contents of the archive) (For distribution on pcfs floppy disks (IBM PC format), the file names may not appear exactly as shown above.) Documentation on using the above programs is included in README files in each directory. Documentation describing the internal operation of LPC-10 is currently available only in hardcopy format. We will include more extensive documentation with future releases of this package. All development of LPC-10 has been done in Fortran, so the Fortran code has been written for flexible and easy use in a research environment. The C version was translated from the Fortran to assist in porting LPC to Digital Signal Processors (DSPs), and does not have the debugging features or I/O flexiblility of the Fortran version. Both versions have been tested on a Sun SPARCstation-10 running Solaris 2.2 and SunOS 4.1.2. The speech files are in 16 bit linear format, sampled at 8000 Hz. There are no headers on these files, so some manipulation may be required to play them on your system. The following alias will play speech files on the Sun speakerbox: alias play 'audioconvert -i pcm16,mono,raw,r=8k -f sun \!* | audioplay' play dam9.spd
