The ACELP (Algebraic CELP) algorithm used in the TETRA system is studied,which is a typical speech coding algorithm based on the improved CELP algorithm.In order to test the practical effect of this algorithm,the VS2005 is used to carry out the compression and decompression of the data acquired by sound card and play it back after 10s in the Windows XP environment.The whole process uses lots of the core Windows development knowledge and gives out the key part of the source code.This could be useful for speech coding researchers and programmers.
