G.728 implementation in C

This program implements the 16 kb/s Low-Delay CELP algorithm (ITU-T Recommendation G.728) using floating point. The input speech files should be 2-byte per sample and contain no header. The input can use the full 16 bit range. The bitstreams are written as 2-bytes per 10-bit codeword. This code was test on SUN and SGI platforms using the gcc and cc compilers.
