ITU G.728

ITU-T recommendation G.728 Annex G is the fixed-point version of the recommendation G.728: coding of speech at 16kbps using Low Delay Code Excited Linear Prediction (LD-CELP). It uses backward adaption of predictors and gain to achieve an algorithmic delay of 0.625 ms. Under error-free transmission conditions, the perceived quality of a 16kbit/s LD-CELP codec is equivalent to that of a codec conforming to 32 kbit/s ADPCM.

The ESPICO implementations are highly optimised, realising low memory and MHz requirements. Contact ESPICO for specific resource requirements.
