This directory contains the source code for the "fast" and "efficient" two versions
of F1016 standard CELP speech compression/decompression algorithm.
The code has been modified by Chengxiang Lu and Alex Hauptmann from the Speech Group,
Computer Science Department, Carnegie Mellon University to be fairly fast
and efficient, while retaining high fidelity.
Directory of "decoder" contains all the code to decompress an encoded file.
Usage: celp_decode <*.chan > *.spd
Directories of "efficient_encoder" and "fast_encoder" contain all the code to
compress a raw speech file. "efficient" version is slower than "fast" version, but
with relatively higher qulity.
Usage: celp_encode <*.spd >*.chan
If you have questions, please contact Alex Hauptmann (alex@cs.cmu.edu)
or Chengxiang Lu (lu+@cs.cmu.edu).
