信号的hilbert变换,C＋＋代码,不用matlab的可试试(the c++ code for the hilbert transform)

melpe 编解码 程序 melpe 编解码 程序melpe 编解码 程序 melpe 编解码 程序(melpe decoder)

说明：  MeLPe Codec 1200 bps

说明：  源程序中包含PCMu率与PCM线形之间的编解码(source contains PCMu rate between the linear PCM codec)

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.)

MMSE语音降噪算法，使用维纳滤波器的方法，运算量适中，能实时处理(MMSE weiner noise reduction)

滤波器设计 　　　产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计低通，带通，高通滤波器对信号进行滤波处理，观察滤波前后信号的频谱。(The filter is designed to generate a continuous signal containing the low, mid, and high frequency components, to be sampled, for spectral analysis, respectively, to design a low-pass, band-pass filter processing is performed by a high-pass filter on the signal, the spectrum of the signal of the observation before and after filtering.)

说明：  用matlab实现压缩感知，基追踪（BP）算法，将最小L0问题转化为最小L1问题。(Use matlab to implement compressed sensing, base tracking (BP) algorithm, convert the minimum L0 problem into the minimum L1 problem.)

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,)

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)
