The Adaptive Digital Technologies G.722 Audio Coder is a real-time implementation of the ITU G.722 audio coder. It is used with many applications that require audio frequency bandwidth coding such as video conferencing, multimedia, and speaker/microphone digital telephony. The G.722 audio coder encodes 16 kHz sampled audio signals for transmission over 48, 56, and 64 kbps channels, and provides 7 kHz of audio bandwidth.

Functions are C-callable
Multi -Channel Implementation.
Can be integrated with echo cancellers, VOX and tone detection/regeneration.
Can be integrated with G.711/G.728 to provide the audio portion of the H.320 video standard.
The encoder and decoder meet all ITU G.722 compliance data files.
ADT G.722 is available on the TMS320™ DSP Family
