Description
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
