很经典的MELP的MATLAB算法仿真。从一个外国网站上下载，很棒(MELP is the classic algorithm of the MATLAB simulation. From a foreign website, great)

说明：  MeLPe Codec 1200 bps

dtmf 拨号程序，Pocket PC ，vc 工程演示(dialDTMF a Pocket PC (Pocket Contact) plugin to dial telephone numbers using DTMF s (aka Dual Tone Multi-Frequency) (tested under PPC2000 MIPS, PPC2000 ARM, PPC2002 ARM, Xscale WMPPC2003 and WM2003SE, WM5- if you want your processor supported either build the exe s yourself from CVS or email me and I may look into it). There is a listed of known working hardware in the FAQ.)

语音压缩 自适应差分脉冲调制编码 即ADPCM 用matlab开发 (Adaptive differential pulse-modulated voice compression coding using matlab development that ADPCM)

假设一段语音信号，用其作为序列，编程实现LBG算法产生码书。(Assuming a speech signal, use it as a sequence, programming the LBG algorithm to generate the codebook.)

语音信号的矢量量化，其中vector_quantization.m为读取音频文件，转换成语音帧，求lpc及lsf参数以及进行矢量量化的主程序，a_lsf_conversion.m为主程序调用的lpc转lsf参数的子程序，INLS1.wav为音频文件。(Vector quantization of speech signals, wherein vector_quantization.m to read audio file, converted into speech frames, seeking lpc and lsf parameters and vector quantization of the main program, a_lsf_conversion.m main program calls a subroutine parameter lsf lpc turn, INLS1.wav as an audio file.)

说明：  这是一个从音频信号里提取特征参量的程序，从事此方面的同志，不妨参考(This a signal from the audio extract features parametric procedures, engaged in this regard, the comrades might reference! !)

基于麦克风阵列用盖尔圆法进行信源数目估计。输入数据位麦克风采集的信号，阵元数目为10.(Based on microphone array，the number of sources is estimated by Gerschgrid method. Input data is obtained by microphone array and the number of array elements is 10.)
