说明：  ADPCM算法目前已成为很受用的语音压缩算法之一。给出PCM概念。讨论DPCM,DM,ADM与ADPCM的 压缩算法原理以及算法实现流程框图。通过实验,指出每个算法的特征。实验结果进一步证实ADPCM算法既能够有效的 压缩语音,又能还原出高质量的语音。
(ADPCM algorithm has become popular with one voice compression algorithm. PCM given concept. Discussion DPCM, DM, ADM and the ADPCM Compression algorithm principle and algorithm flow diagram. Through the experiment, characterized in that each algorithm. Experimental results confirm both the ADPCM algorithm can effectively Compressed voice, but also to restore the quality of the voice.)
