中文说明：应用背景当2个或更多的源正在讨论的麦克风，它变得很难找到的区别的来源。演讲的卷积来决定是否被分离。1。输入被记录并存储在工作文件夹中。2。 ；功能配套calcfft。M，calcifft。M和M multiply3；以及在同一个工作文件夹中的程序和音频文件。3。输入信号通过主程序作为参数传递。4。 ；程序必须运行在MATLAB 7.0.45。输出将被存储在工作文件夹后，该程序是执行。关键技术语音处理技术是用来确定什么可以做的，此外，对盲信号提取的地方只有一个主要的语音源是理想的，一个组合的计划组成的建议盲源分离和后处理，如噪声消除器，提供令人印象深刻的噪音抑制水平，同时保持低的目标信号失真水平。
English Description：
Application background When two or more sources are talking over the mic, it becomes difficult to find the difference between the sources. Convolution of the speeches are done to determine if they are separated. 1. Inputs are recorded and stored in the work folder. 2. The supporting functions calcfft.m, calcifft.m and multiply3.m has to be in the same work folder as the program and the audio files. 3. The input signals are passed on to the main program as parameters. 4. The program has to be run on MATLAB 7.0.4 5. The outputs will be stored in the work folder after the program is executed. Key Technology voice processing technology is used here to determine as to what can be do In addition, for blind signal extraction where only a main speech source is desired, a combined scheme consisting
