| Abstract: | Nowadays, ADPCM algorithm is one of the useful speech compression algorithm. We first introduce the concept of PCM. Then we discuss the principle of DPCM, DM, ADM, ADPCM compression algorithm and its implementation flowchart. Finally, we poiot out the character of every algorithm through experiments. The experiments results show that ADPCM algorithm can not only compression speech effectively, but also decode high quality of speech. |
