光谱预处理源程序2

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)

说明：  《VC视频音频编解码技术及实践》书的光盘代码(&quot VC video audio codec technology and the practice of&quot book on CD-ROM code)

说明：  MeLPe Codec 1200 bps

富迪FM2018语音净燥及消侧音的专用IC开发资料,pdf格式,找了好久才找到的东西,(Fudi FM2018 voice net dry and antisidetone dedicated IC development information, pdf, looking for a long time to find something,)

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.)

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! !)

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.)

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.)

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.)
