CODECPRO G.722.1 CODEC
ITU-T STANDARD CODEC

The G.772.1 was developed to deliver wideband speech and music at lower bitrates than G.722. The G.722.1 standard is limited in scope to hands-free operation and low packet loss conditions. G722.1 operates in wideband at 7 kHz and provides two bitrates at 24 and 32 kbps. G.722.1 Annex C (G.722.1C) supports super-wideband at 14 kHz and adds a new bitrate at 48 kbps.
