ADPCM(Adaptive Differential Pulse Code Modulation),是一种针对 16bits( 或8bits或者更高) 声音波形数据的一种有损压缩算法,它将声音流中每次采样的 16bit 数据以 4bit 存储,所以压缩比 1:4. 而且压缩/解压缩算法非常简单,所以是一种低空间消耗,高质量高效率声音获得的好途径。保存声音的数据文件后缀名为 .AUD 的大多用ADPCM 压缩。

利用Matlab仿真脉冲编码调制(PCM)及A律、μ律PCM对声音进行压缩编解码过程。
脉冲编码调制(PCM,Pulse Code Modulation)是一种将模拟语音信号转换成数字信号的编码方式。波形编码器的作用是对采样后的信号样本进行量化和编码。从数学上来看,量化过程就是把一个连续幅度值的无限数集合映射成一个离散幅度值的有限数集合,编码就是用一组二进制数来表示这些映射后的有限数。国际标准化的PCM采用折叠二进制码,符合长途电话质量。根据量化方法的不同,PCM可分为均匀量化PCM和对数
