Codebook Excited Linear Prediction (CELP) is one of the most widely used class of speech coders which is based on the concept of LPC. The enhancement is that a codebook of different excitation signals is maintained on the encoder and decoder. The encoder finds the most suitable excitation signal sends its index to the decoder which then uses it to reproduce the signal. Hence the name Codebook Excited is given to this coder. There are many variants of CELP that are in use in various applications. Low Delay CELP (LD-CELP) and Algebraic CELP (ACELP) are generally used in internet voice calls and cell phones.

MPEG-4 Audio Lossless Coding (ALS) is a new extension of the MPEG-4 audio coding family. The ALS core codec is based on forward-adaptive linear prediction, which oers remarkable compression together with low complexity. Additional features include long-term prediction, multichannel coding, and compression of floating-point audio material. In this paper authors who have actively contributed to the standard describe the basic
