Description: G721-G723 源代码
G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate. The four bit rates associated with G.726 are often referred to by the bit size of a sample, which are 2-bits, 3-bits, 4-bits, and 5-bits respectively.

Description: G726局域网语音通话程序和源代码
这是使用G726语音压缩（16kbps）和RTP进行传输的程序，因为我没有带WIFI的PPC，所以每个程序都是单独测试的，PC端和PPC端分别都工作正常。
G726编解码算法来自OpenH323.传输使用的RTP可以在RTP程序中找到讲解，这个程序主要是G726的函数。将整个 G726封装为g726_Encode和g726_Decode两个函数，参数为压缩和解压数据存储的地址指针，可以将960字节压缩到120字节和将 120字节解压为960字节。这里G726使用的时候，音频设置为8kHz，16位量化，单声道。
使用方法很简单，只用两端各自输入对方的IP，然后按下“开始对话”，就可以进行语音通信了。
PPC端的运行比较稳定，已经进行了自收自发近一个小时连续工作的测试，非常稳定，话音清晰。-G726 LAN voice calls procedures and the source code is the use of voice compression G726 (16kbps ) and RTP for the transmission process, because I did not bring WIFI the PPC, there are separate procedures for each test, PC- and PPC-were all normal work. G726 codec algorithm from the OpenH323. RTP transmission can be used in the process to find RTP stresses Xie, this procedure is mainly a function of G726. Packaging whole G726 for g726_Encode and g726_Decode two functions, Parameters for the compression and decompression of data storage address pointer, 960 bytes can be compressed to 120 to 120 bytes and bytes to 960 bytes decompression. G726 used here, Audio set to 8kHz, 16 quantify mono. It is very simple to use, with only two ends of the respective input each other's IP, then press

这是使用G726语音压缩（16kbps）和RTP进行传输的程序，使用方法很简单，因为没多少时间，并且RTP不面向连接，所以我也没做连接确认的，只用两端各自输入对方的IP，然后按下“开始对话”，就可以进行语音通信了。-G726 LAN voice calls source code (vc 6) This the voice compression using G726 (- ns 16-kb ps) and RTP for transmission, the use of approach is very simple, because no amount of time, RTP and not connection-oriented, so I do not recognize the link, only two ends of the respective input each other's IP, then press the "start a dialogue", it can implement a voice communication.
