Project and source code for ADPCM

The DVI Adaptive Differential Pulse Code Modulation (ADPCM) algorithm was first described in an IMA recommendation on audio formats and conversion practices [1]. ADPCM is a transformation that encodes 16-bit audio as 4 bits (a 4:1 compression ratio).

自适应差分脉码调制算法，源码很好，已经调试过，可以用-Adaptive differential pulse code modulation algorithm, very good source, has been debugged, you can use
