Pls give some docs or links for it !
 

search using mc3418.
 

ADPCM is coding standard for digital transmission . The ITU-T G.726 standard could be related to this . It provides 2 times less data flow compared with PCM standard
G703 (if I am not wrong) at speed 32 kB/s.
But there could be implementations that give better compression ratio
