AUDIO CODER

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.

FEATURES

  1. Functions are C-callable

  2. Multi -Channel Implementation.

  3. Can be integrated with echo cancellers, VOX and tone detection/regeneration.

  4. Can be integrated with G.711/G.728 to provide the audio portion of the H.320 video standard.

  5. The encoder and decoder meet all ITU G.722 compliance data files.

AVAILABILITY

ADT G.722 is available on the TMS320™ DSP Family
