Low Delay Code Excited Linear Prediction (LD-CELP)

Complete Definition

Low Delay Code Excited Linear Prediction (LD-CELP), Delay of the codec is   only 5 samples (0.625 ms). The linear prediction is calculated backwards with a   50th order LPC filter. The excitation is generated with gain scaled VQ. The   standard was finished in 1992 in the form of algorithm exact floating point   code.

LD-CELP is based on CELP
