Description: The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor). My colleague Dr. Carsten Bormann and I have implemented a GSM 06.10 RPE LTP coder and decoder in C. Its source code is freely available, and we encourage you to use it, play with it, and invent new real time media protocols and algorithms.
Our implementation consists of a C library and a stand alone program. Both are destined to be compiled and used on a Unix like environment with at least 32 bit integers, but others have ported it to VMS and a MS DOS 16 bit environment. GSM 06.10 is faster than code book lookup algorithms such as CELP, but by no means cheap to use it for real time communication, you will need at least a medium scale workstation. -The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor).

Description: G.729的全名Code Excited Linear Prediction Model (CELP) and Conjugate-Structure Algebraic CELP (CS-ACELP). 共轭结构-代数码激励线性预测编码.
G.729家族一共包括三个版本G.729, G.729A,G.729B,G.729AB:
G.729 是G.729的第一个版本,
G.729A 相对于G.729简化了算法.
G.729B 给G.729增加了静音压缩的算法.
G.729Ab 给G.729A增加了静音压缩的算法.
G.729属于合成分析(abs)的语音编码方法,这种方法在中低比特率的情况下可得到较好的语音质量.
编码工作于10ms的语音帧上,8K采样率,具有80个样点,,对每一帧提取CELP模型的有关参量(LP滤波器系数,自适应码书和固定码书的指针和增益),这些参量被编码和传送.在解码器中,这些参量被用来恢复激励信号和合成滤波器的参量.语音信号由激励信号通过LP合成滤波器重构得到.
注：8000Hz采样率，16位样本，压缩率为16:1，80个16位样本经过编码后为10个8位编码串；我用G.729a试过，语音还可以，音乐就不行了。另：商业应用G.729每个许可是10美元，一个许可就是一路通话；不知道现在还是不是。
