DirectShow开发指南
- 本书以DirectX SDK 9.0版为蓝本，涉及的内容几乎涵盖了在Windows平台上使 用DirectShow进行C++编码的方方面面。全书共分4个部分。第1部分详细介绍了 DirectShow的基础知识。第2部分重点讨论了Filter的开发，以及DirectShow 应用程序的开发，包括目前非常流行的如音视频采集、数码摄像机的支持、非线性 编辑等应用。第3部深入分析了DirectShow SDK提供的部分典型源代码例子。第 4部分结合作者个人的一些开发实践，通过案例和开放源码分析
wiener filtering
- 实现了维纳滤波对语音信号的去噪，输入一段音频文件，取单声道，加噪声后进行滤波(Wiener filtering The Wiener filter is used to denoise the speech signal, input a segment of audio file, take the single channel, and filter the noise after adding the noise)
VoiceProcess
- 通过激励信号与合成滤波器，获得重建信号，生成语音变速滤波器与语音变调滤波器，得到变速变调音频。(Through the excitation signal and the synthetic filter, the reconstruction signal is obtained, the voice transmission filter and the voice modulation filter are generated, and the variable tone audio is
lvboqi
- 在matlab中设计不同阶数的FIR滤波器,并对音频文件进行读入，分别对左声道和右声道进行滤波，分别满足35阶FIR滤波器和315阶FIR滤波器，输出音频文件，并进行滤波效果的对比。(In the MATLAB, FIR filters with different orders are designed, and the audio files are read in. The left and right channels are filtered respectively, which s
matlab-dsp-语音信号处理
- 利用matlab将自己的录好的音频加入噪声后，在利用滤波器滤除噪声，回复原始音频(After using MATLAB to add its recorded audio to noise, the filter is used to filter the noise and restore the original audio.)
