Codec ITU G.728,729

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