Microsoft ADPCM Format / G. Four 64 kbps channels (PCM octets) are compressed into four 32, 24 or 16 kbps ADPCM channels (ADPCM words), and four 32, 24 or 16 kbps ADPCM channels (ADPCM words) are expanded into four 64 kbps PCM channels (PCM octets). These two, folding ADPCM and QMF ADPCM, are intended to pave the way for smooth transition from conventional 4-kHz band telephone systems to 7-kHz wideband systems in private networks. The CCITT ADPCM standard is much more complicated, probably resulting in better quality sound but also in much more computational overhead. In Awave Audio you instead select this in the 'More options ' dialog. Secondly, a synchronous coding adjustment module is included at the output of the decoder. Instead of encoding the speech sample, ADPCM encodes the difference between a predicted sample and the speech sample. The chip can be programmed to compress (expand) 64kbps voice data down to (up from) either 32kbps, 24kbps, or 16kbps. It finds its origin in the non-reciprocity between linear PCM word (14 bits) and logarithmic PCM word (8 bits).
