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.

The memory and CPU details are generic Standard specifications, for more detail and information about CodecPro's G.722.1 optimisation, please contact us at
