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)

可以对处理后的语音进行一个客观上的评判，提供客观评价因子。(It is possible to make an objective evaluation of the processed speech and provide an objective evaluation factor.)

A率13折线的编译码实现 1、了解PCM及13折线A率编码及译码的原理； 2、随机给出一个语音信号，并用A率13折线PCM对其编码； 3、将编码后的信号经过加性高斯白噪声信道，并在接收端对其进行译码； 4、分别画出原始语音信号、PCM编码信号以及译码后信号的波形。 (A rate of 13 polyline encoding and decoding implementation 1, to understand the principles of PCM and the broken line 13 A rate of encoding and decoding Two were given a voice signal, and PCM encode A rate of 13 polylines 3, the encoded signal through an additive white Gaussian noise channel, and the receiver decodes 4, respectively, to draw the waveform of the original speech signal, the PCM encoded signal and decoding signals.)

是FM调频立体声的调制解调的matlab仿真代码，实现了对双声道语音的调制和解调，非simulink方式，完完全全的matlab代码(This is for FM stereo radio signal modulation and de-modulation code. it is not for matlab simulink, it is completely matlab code, you can follow it and for understanding FM stereo signal generate very well.)

g729a音频编码库,编码pcm为g729a,可压缩16倍(G729a library audio coding, coding PCM for g729a, compressible 16 times)
