Description: 已经验证过的ITU G.729B源码
1.使用定点运算, 纯c实现
2.已经附带了VC6的项目文件(原始的ITU源码只有makefile,没有VC项目文件), 方便初学者入门使用
3.用于测试G.729编码和解码
4.主要应用于VoIP项目-has tested the ITU G.729B a source. Operational use of sentinel, 2-c achieve. has been accompanied by VC6 project document (original source of the ITU only makefile. no VC project document), Introduction to facilitate the use of three beginner. G.729 test for coding and decoding 4. VoIP will be used in the project

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。
