G.723.1

An ITU standard for speech codecs optimized for modems. It uses the LD-CELP method and provides toll quality audio at 5.3 or 6.4 Kbps. The higher rate requires less processing power. It also provides a mode where one person speaks at a time and uses the extra bandwidth for the talking party. See G. standards.
