ADPCM adaptive differential pulse code

ADPCM Adaptive differential pulse code modulation. 

ADPCM (adaptive differential pulse code modulation) is a very popular audio compression system, widely used in telephony, HDTV, and many other applications. It is also a common codec nsed for compressed Windows. wav files. Not all applications can read ADPCM encoded. wav files, but most can. While ADPCM files are nsnally significantly smaller than PCM files, they are still not usually compressed as much as other Internet targeted codecs.
