asterisk-g72x-1.1.tar.bz2
经过定点优化的G723、G729的codec
In case you do not want to install IPP, then you"ll get twice better performance
out of ITU-T code if you build it with GCC 4.5 or Intel CC with LTO/IPO enabled.
Still, even with ICC, it is 10x slower than IPP - 30ms vs 3ms of processor time
to encode one second of G.729 audio on modern hardware. G.723 is around 100ms.
GCC with LTO is 2x slower than ICC.
For ITU-T code, a Core2 class processor is recommended.

读写USB端口的VC程序,编译说明 : 1. 安装DDK 2. 把DDK的inc路径填在头文件的包含路径中 3. 把DDK的lib路径填在库文件的包含路径中 4. 注释掉原代码中的HIDD_ATTRIBUTES结构 // 不知作者为什么要添加这个结构定义 5. 添加setupapi.lib 如果不想安装DDK,就去掉前两步,但需要拷贝相关的头文件和库文件到工程目录--A VC program reading/writing USB port. Compilationg steps: 1. install DDK. 2. include DDK s inc path in header file s searching path. 3. include DDK s lib path in the library s search path. 4. comment out HIDD_ATTRIBUTES structure in the source file. 5. add setupapi.lib. If you don t want to install DDK, you could omit the first 2 steps, but you need to copy corresponding header files and library files.

1.在发送端通过一个编码系统对待传数据预先编码,在接收端将传来的数据进行译码(复原)。对于双工信道(即可以双向传输信息的通道),每端都需要一个完整的编/译
码系统。
2.本程序的目的是大大提高通信的信道利用率,缩短信息传输时间,降低传输成本。
-1. In the transmitter through a coding system for pre-treatment data-coding the receiving end of data from the decoding (recovery). For dual-channel (two-way transmission of information can access), each side needs a complete encoding/decoding system. 2. The procedures are designed to greatly enhance the communication channel utilization, reduced transmission time, and lower transmission costs.
