Description: iLBC 产生背景
在VoIP的应用中，大部分厂商采用CELP (Code Excited Linear Prediction) 算法的低速率语音编解码，如ITU G.729和G.723.1等。而VoIP应用主要在包交换的IP网络上进行传输，无法避免IP网络的丢包、延时、抖动等实时传输问题，而传统的这几个CELP算法对高丢包的处理不是很好，因而很大程度上会影响语音通话效果。
-iLBC background in the application of VoIP, Most manufacturers to use CELP (Code Excited Linear Prediction) Algorithm low-rate voice codecs, such as G.729 and ITU G.723.1, etc.. And the main application of VoIP in the IP packet-switched network for transmission, could not avoid IP network packet loss, delay, jitter and other real-time transmission, and a few traditional CELP algorithm to handle the high packet loss is not very good, which will largely affect voice calls effect.

编码器实现了G.723.1的多脉冲模式（在6.3 kb / s的运行）。解码器可以解码的5.3 kb / s的，在6.3 kb的多脉冲/秒，连续传输，数据包丢失隐藏）编码器（所有的ACELP方式。
该编码器和解码器之间的标准接口是位文件（同位文件由ITU - T参考代码产生兼容）。第二个选项之间传递的编码器和解码器使用Matlab的数据信息文件。此选项允许测试通过传递量化或unquantized之间的编码器和解码器的信息。
有报道[1]描述了G.723.1编码与Matlab实现与分布包括在内。 ITU - T建议G.723.1的[2]在线提供。该建议含-This program intended to simplify the playing basic of wave sound such as play, pause, stop and resume.
Since i notice in www.mathworks.com less people have the solution to how to stop wave sound from playing , so i try to do this and post it here.
Hope you guys enjoy the program :P

Description: Abstract - In this paper, proposed an efficient method of
converting speech codec formats between G.723.1 and
G.729А. The proposed method is composed of four steps:
LSP conversion, pitch conversion, adaptive codebook
search and fixed codebook search. Subjective results
shown that the proposed method has shorter delay than
classical tandem method.- Abstract- In this paper, proposed an efficient method of
