# CODECPRO G.722 CODEC  ITU-T STANDARD CODEC

Developed for use in ISDN videoconferencing, G.722 was the first wideband speech codec to be standardized by the ITU-T. By sampling the speech signal at 16 kHz, G.722 more than doubles the encoded speech information, providing richer sound and better clarity than narrowband speech codecs.
